Why can’t I display this folder in Outlook?

Cannot display the folder error in Outlook is likely to occur when your Outlook data file is corrupted. The lack of necessary folder permissions can be another reason you get this error.

Fix Cannot display the folder error in Outlook

Here are the solutions you can use to fix the Cannot display the folder error in Outlook:

1. Repair or delete the OST file.
2. Check folder permissions.
3. Delete old items, if applicable.
4. Change the default public folder mailbox (Hotfix).

1] Repair or delete the OST file

This error is likely to occur due to a corrupted Outlook data file. So, you can try repairing the OST file or deleting it to fix the error. Some affected users have reported resolving the error using this method.

To repair the OST file, you can use the below steps:

• First, exit the Outlook app completely using Task Manager.
• Now, move to one of the following locations:

  C:\Program Files (x86)\Microsoft Office\root\Office16
  C:\Program Files\Microsoft Office\root\Office16
  C:\Program Files\Microsoft Office\Office

  Note: The above location will differ as per your computer architecture and the version of Office installed on your system.

• Next, locate the SCANPST.EXE file and double-click on it to open it.
• After that, browse and select the input Outlook data file.
• Lastly, click on the Start button to repair the file.

Once done, restart Outlook and see if the error is gone.

If repairing the file doesn’t work, you can delete or rename the Outlook OST file and force Outlook to recreate it. Here are the steps to do that:

• First, close Outlook and open the Run command box using Win+R.
• Now, enter the following command in the Open box:

  %LOCALAPPDATA%\Microsoft\Outlook

• Next, locate the OST file and create a backup in another location.
• Once the backup is created, delete the OST file or rename it.
• After that, reboot your computer and open Outlook.

Outlook will create a new OST file. You can try accessing the folder and see if the error is fixed.

2] Check folder permissions

It could be a restricted permission, which is why you are getting the “Cannot display the folder” error message. Change the folder permission for a shared Outlook account that is getting this error.

Note: You have to be an administrator to change Outlook folder permissions for an account. If you keep getting this error, contact your IT admin to get the folder permission changed.

Here’s how to do that:

• First, move to the Folder pane in the left-hand side panel.
• Now, right-click on the problematic public folder under the Public Folders section and choose Properties from the context menu.
  Note: In case the Public Folders are not visible, press Ctrl+6.
• Next, go to the Permissions tab and choose the user you want to edit permission.
• If you can’t see a specific user or group on the list, click on the Add button and then add users or groups from the Global Address List.
• After that, set Permission Level to Custom and tick the permissions you want to assign to the selected users. Make sure to tick the Folder Visible box.
• Finally, press the OK button to save changes.

This should fix the error for affected users now.

A few affected users have also reported that removing and then re-adding the permissions to public folders resolved the issue for them. You can try doing the same and see if the error is fixed.

3] Delete old items, if applicable

If you are getting one of the below error messages, consider deleting old or unnecessary items first to make some space in your mailbox and fix the error:

Cannot display the folder. The message store has reached its maximum size. To reduce the amount of data in the message store, select some items that you no longer need, and permanently (Shift + delete) delete them.

You can use Outlook’s built-in Mailbox Cleanup tool to make some space in your mailbox.

There are several other ways to clear up space on Outlook. See if this helps.

4] Change the default public folder mailbox (Hotfix)

Some admins have reported that changing the default public folder mailbox for their users fixed the issue. You can do the same and see if the error is fixed. Here’s how:

First, open Exchange PowerShell and then enter a command in below syntax:

Set-Mailbox -Identity <username> -DefaultPublicFolderMailbox "PublicFolderMailboxName"

Once the default folder is set for the specified user, check if the error is fixed.

Why can’t I display the folder in Outlook search?

If Outlook search is not fetching results and displaying folders, the indexing options might not be set up correctly, or there are some indexing issues. To fix the issue, verify the Outlook indexing status, ensure the Windows Search service is enabled, rebuild the Windows Search catalog, or modify indexing options.
