Troubleshooting outlook
This article will help you fix errors related to the Outlook service.
Re-granting permissions for the mailbox.
Re-granting is possible only if there is a problem with the mailbox; if there is no problem, this item will not be displayed in the dropdown menu. When re-granting permissions, messages that were not processed due to errors will be processed. If you delete and re-add the mailbox, the messages will not be processed.
Open the settings page and find the mailbox with the problem.
Open the dropdown menu and select the “Grant access” option.
Log in with an account that has the necessary permissions for this mailbox.
Wait for the mailbox setup to complete.
Ensure that the error is resolved.
