Like Exchange accounts, Office 365 accounts also can be configured in Outlook. It helps Office 365 users to manage emails and other mailbox data more efficiently. Though convenient, it can create issues too. For example, when configured with Office 365 account, sometimes you may face the following message while opening Outlook:
Your mailbox has been temporarily moved to Microsoft Exchange server.

Method – 4. Use ScanPST

ScanPST is an inbuilt repair tool which scans the PST file and repairs it for minor errors. You can run the ScanPST application from its location and scan quickly. But it is essential to take a backup of the PST file before using the ScanPST because the tool can delete some data from the mailbox and restore the remaining data. It will allow you to use the account, but the deleted data will not come back.

Method – 5. Disable unnecessary add-ons

There may be some unnecessary add-ons which may be stopping the opening of Outlook. The user should disable these add-ons one by one and check if the account gets opened.

Method – 6. Disable anti-malware

There are some anti-malware software(s) which checks the incoming messages to your account and stops them if they are fishy. It also checks the mailbox content and deletes the harmful messages. You can disable this anti-malware software or prevent them from blocking the messages.
After using these troubleshooting methods, you will be able to operate Outlook again. But there are many chances that you have to either lose the mailbox data or delete the account. To save the OST file data, use OST to PST conversion methods, such as, Kernel for OST to PST, which converts OST files to the PST and recovers the data. It is the best method to recover an OST file to PST format and get the entire data in full health. Another advantage of this tool is that you can save OST data directly to Office 365, Exchange Server, Gmail, or other popular destinations. So, this is the best tool for OST to PST conversion.

Final Words

With an Office 365 account configured in Outlook, users may sometimes get an error:– ‘Your mailbox has been temporarily moved to Microsoft Exchange Server.’ It is a simple error that can be fixed by changing the Outlook profile or recreating it. But if Outlook users face an issue due to OST file inaccessibility, they can convert the OST file to PST.
