When setting up in Office 365, Outlook keeps asking for a temporary mailbox issue. Many users encounter the “Your mailbox has been temporarily moved to Microsoft Exchange Server” issue. This “outlook use temporary mailbox” error occurs when the Outlook profile is corrupted or automatically configured in Microsoft Exchange Server.
If you have set up an Office 365 account, you may get the following message when you open Outlook:
Your mailbox has been temporarily moved to Microsoft Exchange Server.
The temporary mailbox exists, but it may not contain all of your previous data.
You can connect to the temporary mailbox or work offline with all your old data.
If you choose to work with the old data, you will not be able to send or receive emails.
In this article, we will describe some manual methods to help you solve the “Your mailbox has been temporarily moved to Exchange” problem.
What causes the ‘Your mailbox has been temporarily moved’ problem?
This error usually indicates that the Outlook profile is corrupt. To resolve this issue, follow the troubleshooting steps below and make sure that the Outlook profile is working properly after each step.
The error can also occur after you have migrated your mailbox. If your mailbox was recently moved to a new platform, go to step 3 (Rebuild Profile).
We strongly recommend that you back up your Outlook data before making any changes.
It is possible that some messages are only stored on the local computer and are not synchronized with the server due to a corrupt Outlook profile.

However, it is important to back up your PST file before using ScanPST because the tool may delete some data from your mailbox and restore the remaining data. This way, you can continue to use the account, but the deleted data will not come back.
Disable unnecessary add-ons
It is possible that some unnecessary add-ons are preventing Outlook from opening. The user should disable these add-ons one at a time and see if the account can be opened.
Disable anti-malware protection
There are one or more antivirus programs that check incoming messages to your account and stop them if they are suspicious. It also checks the contents of your mailbox and deletes malicious messages. You can disable this antivirus software or prevent messages from being blocked.
After applying these diagnostic methods, you can use Outlook again. However, there is a chance that you will lose mailbox data or delete the account. To recover data from the OST file, use conversion methods like Kernel for OST to PST, which converts OST files to PST and recovers data from it. This is the best way to recover the OST file to PST format and get all the data in full.
