If you can view them with another program (mac mail, OWA) and they are in the inbox in the other program then they are still there. It is most likely a view filter issue. Pre-Flight Check. Outlook 2016/2019 cannot connect to the mailbox When using the automatic configuration option to configure an Outlook profile, you may face the following error. We are having trouble connecting to your account. Verify the settings below and make changes if necessary.

Symptoms

Consider the following scenario:

• You're using Microsoft Outlook 2019, Outlook 2016, Outlook 2013 or Outlook for Office 365.

• You're connected to an Exchange Server mailbox.

  Notes

  • If you're running Outlook 2019, Outlook 2016, or Outlook for Office 365, this account might be your primary mailbox or another mailbox to which you have delegate access or another permission. This might be an additional, shared, or automapped mailbox, or public folders.

    For more information about this issue in Outlook 2019, Outlook 2016, or Outlook for Office 365 related to shared mailboxes or public folders, see the following article in the Microsoft database:

    3140747 Only a subset of items is synchronized in shared mailboxes or public folders in Outlook 2016

    • If you're running Outlook 2013, the account must be your primary account.

• Your Exchange email account is configured to use Cached Exchange Mode.

In this scenario, the email folders for these mailboxes may show item counts that are lower than expected. Additionally, older items may seem to be missing, and you might receive the following message and hyperlink at the bottom of the list of items:

There are more items in this folder on the server

Click here to view more on Microsoft Exchange

This message is shown in the following screenshot.

Additionally, if you search for email items in your mailbox, the search results may display the following text at the bottom of the results:

Showing recent results..

More

If you click the More link, additional items that meet your search criteria are displayed in the search results. This occurs because Outlook retrieves the additional items from your mailbox on the server that's running Exchange Server.

Note

This behavior can also occur in the RSS Feeds folder in your Exchange mailbox. Also, only a subset of items may be synchronized in groups in Outlook 2016 or Outlook for Office 365.

Cause

This behavior occurs because the Cached Exchange mode Mail to keep offline setting is configured to a value other than All. For example, the following screenshot shows a profile that's configured to use Cached Exchange Mode and the Mail to keep offline setting is set to a default value of 12 months.

Note

Outlook 2019, Outlook 2016, Outlook 2013 and Outlook for Office 365 provide the options of 1, 3, 6, 12, or 24 months, or All. Outlook 2019, Outlook 2016, and Outlook for Office 365 provide the additional options of 3 days, 1 week, and 2 weeks.

In the default configuration, depending on the size of your hard disk, Outlook synchronizes only 1, 3, or 12 months of email to your Offline Outlook Data (.ost) file from the Exchange server.

If your Mail to keep offline setting is set to 12 months and you have email items in your Exchange mailbox that are older than 12 months, those items reside only in your mailbox on the server. Therefore, if you can't connect to the Exchange server, you may be unable to retrieve items outside the range that's specified by the Cached Exchange Mode synchronization setting until you reconnect with the server.

Note Free adobe downloads for mac pro.

This setting does not affect the number of items that are synchronized with folders of the following types:

• Calendar
• Contacts
• Tasks
• Journal
• Notes
• Outbox
• Shared or delegated (only for Outlook 2013)

Note

Groups folders only synchronize a maximum of 1 year. Mail to keep offline settings that are lower than 1 year are honored.

More Information

To reduce the effect of the Outlook offline data file (.ost), the default number of months that are configured for your profile varies by the size of your hard disk. The following table provides the different default values for different hard disk sizes.

If you have to change the number of selected months of email to synchronize with your cached mode '.ost' file, follow these steps:

1. Start Outlook.

2. On the File tab, click Account Settings, and then click Account Settings.

3. On the E-mail tab, double-click your Microsoft Exchange account.

4. In the Change Account dialog box, drag the Mail to keep offline slider to the desired number of months or to All to synchronize all email messages.

5. Click Next.

6. Click OK when you're prompted to restart Outlook to complete the configuration change.

7. Click Finish.

8. Restart Outlook.

Working Offline

If you don't have connectivity with the Exchange server, the following message is displayed in a folder if there are older items on the server that were not synchronized with your .ost file:
There are more items in this folder on the server

Connect to the server to view them

This message is shown in the following screenshot.

Under similar conditions, if you search for items in your mailbox and you don't have connectivity with the Exchange server, the following message is displayed below the search results:

Server unavailable. <x> months of results shown.

In this message, <x> represents the value that's configured for the cached mode Mail to keep offline setting.

An example of this message is shown in the following screenshot.

Feature Administration through Group Policy

The cached mode Mail to keep offline setting is maintained in the Outlook profile settings in the Windows registry. If you want to administer this setting by using Group Policy, you can use the Group Policy templates. These are available from the following Microsoft websites, depending on your version of Office:

Office 2016, Office 2019, or Outlook for Office 365: https://www.microsoft.com/en-us/download/details.aspx?id=49030

Office 2013: https://www.microsoft.com/download/details.aspx?id=35554

The Group Policy template files for Outlook 2016, Outlook 2019, and Outlook for Office 365 are Outlook16.admxand Outllk16.adml. The files for Outlook 2013 are Outlk15.admx and Outlk15.adml. If you use Group Policy to manage this setting, the following registry data is used by Outlook:

Key: HKEY_CURRENT_USERSoftwarePoliciesMicrosoftOffice*x.0*OutlookCached Mode

DWORD: SyncWindowSetting

Value: integer value (Decimal) specifying the number of months (use only the following values)
0 = All (whole mailbox)

1 = 1 month of email items

3 = 3 months of email items

6 = 6 months of email items

12 = 12 months of email items

24 = 24 months of email items

Notes:

• The x.0 placeholder represents your version of Office (16.0 = Office 2016, Office 2019 or Outlook for Office 365, Office 2019 or Outlook for Office 365, 15.0 = Office 2013).

• The Outlook 2016, Outlook 2019 or Outlook for Office 365 user interface (UI) lets you set the Mail to keep offline setting to the additional values of three days, 1 week, and 2 weeks. The May 3, 2016, update for Outlook 2016 allows you to set these additional values by using the SyncWindowSettingDays registry data. For more information about how to configure Outlook 2016 with these additional values, see the following article in the Microsoft Knowledge Base:

  3115009 Update allows administrators to set additional default mail and calendar synchronization windows for new Exchange accounts in Outlook 2016.

• Administrators who change the existing GPO values should be aware of the potential to impact network traffic when raising the value of the SyncWindowSetting. When GPO changes SyncWindowSetting to any higher value, Outlook will do a full OST resynchronization when the new value applies. For a single client, this is not problematic. Applying a higher value to hundreds or more clients at the same time could adversely affect available network bandwidth. Decreasing the value will have no such impact because Outlook will do a local-only deletion of excess data that's cached in the OST files of all clients to receive the lower SyncWindowSetting value.

• Since Outlook only synchronizes a maximum of one year for groups, you are unable to search for older messages. To work around this Outlook limitation, use Outlook on the Web to view and search for older messages in groups.

Note

These steps are provided in a specific order based on commonality and complexity. Follow these steps in the given order.

Step 1 - Install the latest updates

Outlook 2016 For Mac Not Showing Full Inbox Email

The Office installation on your computer might not be up to date. This might be because Windows Update is not configured on your computer to automatically download and install recommended updates. By installing important, recommended, and optional updates, you can often correct problems by replacing out-of-date files and fixing vulnerabilities. To install the latest Office updates, click the link for your version of Windows, and then follow the steps in the article:

Make sure that the latest updates for Outlook are installed. For more information, see How to install the latest applicable updates for Microsoft Outlook (US English only).

Step 2 - Make sure that Outlook is not in use by another process

Performance may be decreased if you use the Outlook AutoArchive feature or sync to Outlook with a mobile device. This is because these processes can use a large number of resources.

If Outlook is in use by another process, this information is displayed in the status bar at the bottom of the screen. If you try to perform other actions while Outlook is in use, Outlook may not respond. Let the task in process finish its job before you try another action.

Step 3 - Check the problem that caused by external contents

To resolve this issue, use one of the following methods:

• Prevent Outlook to download external contents. To do this, go to File > Options > Trust Center > Automatic Download, select the following two options:
  • Don't download pictures or other content automatically in HTML e-mail option.
  • Warn me before downloading content when editing, forwarding, or replying e-mail.
• Avoid sending such an email with external source.

Step 4 - Investigate possible add-in issues

Although add-ins can enhance your user experience, they can occasionally interfere or conflict with Outlook. Try to start Outlook without any add-ins running.

How to start Outlook without add-ins

1. Do the following, as appropriate for your operating system:
   • If you are running Windows 8, swipe in from the right edge of the screen, and then tap Search. (If you are using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, and then select Search.) Type Run in the search box, and then tap or select Run.
   • If you are running Windows 10, Windows 7 or Windows Vista, select Start.
   • If you are running Windows XP, select Start, and then select Run.
2. Type Outlook.exe /safe, and then select OK.
3. If the problem is resolved, select Options on the File menu, and then select Add-Ins.
4. Select COM Add-ins, and then select Go.
5. Clear all the check boxes in the list, and then select OK.
6. Restart Outlook.

If the problem does not occur after you restart Outlook, one of the add-ins is likely the cause of the problem. Restore the add-ins one at a time until the problem does occur to determine which add-in is causing the problem.

Outlook Mac Error Not That Many Messages

Step 5 - Check whether your mailbox is too large

As your mailbox size increases, more resources are required to open each folder. If you have a large number of items in any single folder, you may experience performance issues during certain operations. For more information, see Outlook performance issues when there are too many items or folders in a cached mode .ost or .pst file.

We recommend that you move several items in your larger folders to separate folders, or that you archive those items by using the AutoArchive feature.

How to create a folder

1. On the Folder tab, select New Folder in the New group.

2. In the Name box, enter a name for the folder.

3. In the Select where to place the folder list, select the location for the new folder.

   Note

   The new folder will become a subfolder of the folder you select.

4. Select OK.

To manage your mailbox by reducing the size of the Outlook data file, see Reduce the size of Outlook Data Files (.pst and .ost).

To manage your mailbox by using the AutoArchive feature, see AutoArchive settings explained.

Step 6 - Check whether your AppData folder is being redirected to a network location

Outlook stores certain data, such as email signatures and the spelling checker dictionary, in the AppData folder. If the network is performing slowly, Outlook must wait for read and write operations to the AppData directory to finish.

How to disable redirection of the AppData directory

1. Exit Outlook.

2. Start Registry Editor. To do this, use one of the following procedures, as appropriate for your version of Windows:

   • Windows 10 or Windows 8: Press Windows Key+R to open a Run dialog box. Type regedit.exe and then press OK.
   • Windows 7: Select Start, type regedit.exe in the search box, and then press Enter.

3. In Registry Editor, locate and then select the following subkey:

   HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders

4. Locate and then double-click the AppData value.

5. In the Value data box, type the following path, and then select OK:
   %USERPROFILE%AppDataRoaming

6. Exit Registry Editor.

Step 7 - Repair Office programs

You can automatically repair your Office program files to resolve such problems as Outlook freezing or not responding.

How to automatically repair Office

1. Exit any Microsoft Office programs that are running.
2. Open Control Panel, and then open the Add or Remove Programs item (if you are running Windows XP) or Programs and Features (if you are running Windows 10, Windows 8, Windows 7, or Windows Vista).
3. In the list of installed programs, right-click Microsoft Office 2016, Microsoft Office 2013 or Microsoft Office 2010, and then select Repair.

Step 8 - Repair Outlook data files

When you install Outlook, an Inbox repair tool (scanpst.exe) is also installed on your PC. The Inbox repair tool can resolve problems by scanning your Outlook data files, and repairing errors. To use the Inbox repair tool, exit Outlook, and then follow the steps in Repair Outlook Data Files (.pst and .ost).

Step 9 - Check whether antivirus software is up-to-date or conflicts with Outlook

If your antivirus software is not up-to-date, Outlook may not function correctly.

How to check whether antivirus software is up to date

To keep up with new viruses as they are created, antivirus software vendors periodically provide updates that you can download from the Internet. Download the latest updates by visiting your antivirus software vendor's website.

For a list of antivirus software vendors, see Consumer antivirus software providers for Windows.

How to check whether antivirus software conflicts with Outlook

If your antivirus software includes integration with Outlook, you may experience performance issues. You can disable all Outlook integration within the antivirus software. Or, you can disable any antivirus software add-ins that are installed in Outlook.

Important

When you change your antivirus settings, this may make your PC vulnerable to viral, fraudulent, or malicious attacks. We do not recommend that you try to change your antivirus settings. Use this workaround at your own risk.

You may have to contact your antivirus software vendor to determine how to configure the software to exclude any integration with Outlook or to exclude scanning in Outlook.

Note

If you also plan to perform file-level virus scanning of .pst, .ost, Offline Address Book (.oab), or other Outlook files while Outlook is in use, see Plan antivirus scanning for Outlook 2010 or Planning considerations for deploying Outlook 2016 for Windows.

Step 10 - Create a user profile in Outlook

To create a user profile, follow these steps:

1. In Control Panel, select Programs, select User Accounts, and then select Mail to open Mail items.

2. Select Show Profiles.

3. Select the profile that you want to remove, and then select Remove.

4. Select Add.

5. In the Profile Name dialog box, type a name for the profile.

6. Specify the user name, the primary SMTP address, and the password. Then, select Next.

7. You may receive the following prompt:
   Allow this website to configure <[email protected] server> settings?

   In this prompt, select the Don't ask me about this again checkbox, and then select Allow.

Step 11 - Perform a Selective Startup (advanced users)

When you start Windows normally, several applications and services start automatically and then run in the background. These applications and services can interfere with Outlook. A Selective Startup or 'clean boot' process can help you identify problems that are caused by application conflicts.

If you use the Selective Startup option in System Configuration, you can turn services and startup programs on or off individually to check whether the problem occurs the next time that you start your computer. In System Configuration, if you select a check box, the related service or startup program runs when you restart the computer. If the check box is cleared, the service or startup program does not run when you restart the computer.

Follow this procedure to use the process of elimination to identify the problem in Windows 10, Windows 8, Windows 7, or Windows Vista.

Note

For more information about performing a clean boot, see How to perform a clean boot in Windows.

How to do a Selective startup

      Note

      If the problem doesn't reoccur, then you can eliminate the first service as the cause of the problem.

   2. With the first service selected, select the second service check box, and then restart the computer.

   3. Repeat this process until you reproduce the problem.

      Note

      If you can't reproduce the problem, you can eliminate system services as the cause of the problem.

   To determine which startup item is causing the problem

   1. In System Configuration, select the General tab, and then select the Load startup items check box.

   2. Select the Startup tab, select Disable all, select the check box for the first startup item that is listed, and then restart the computer.

   3. While the first startup item is selected, select the second startup item check box, and then restart the computer. Repeat this process until you reproduce the problem.

Step 12 - Create a Windows user profile (advanced users)

Your user profile is a collection of settings that let you customize the computer appearance and performance. It contains settings for desktop backgrounds, screen savers, sound settings, and other features. User profiles help make sure that your personal preferences are used when you log on to Windows.

To determine whether this problem is caused by a corrupted user profile, create a user profile to see whether the problem still occurs when you use the new profile.
