When configured with Office 365 account, sometimes you may face the following message while opening the Outlook:
Your mailbox has been temporarily moved to Microsoft Exchange server.
A temporary mailbox exists but might not have all of your previous data.
You can connect to the temporary mailbox or work offline with all of your old data.
If you choose to work with your old data, you cannot send or receive e-mail messages.
We advise you not to connect to the temporary mailbox as it may cause data loss.
A common reason behind the error is that your Outlook profile is corrupt, and Outlook has automatically connected with Microsoft Exchange Server. Now, you need to run some troubleshooting and check whether the Profile gets open or not.
Note: If it’s already enabled, you can disable it and enable it again after restarting Outlook.
‘Careful, if you remove this profile, offline cached contents for its accounts will be deleted.’
Click the Yes button.
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 (to find Scanpst.exe location, click here) and run it 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.
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.
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 data of the OST file, use OST to PST conversion methods, such as, Kernel for OST to PST which converts OST files to the PST and recovers the data in them. It is the best method to recover an OST file to PST format and get the entire data in full health.
Kernel for OST to PST converter tool needs only a minimum number of steps to convert the OST file, and it retains the whole data in the file without damage. The time of the conversion depends on the size of the OST file, and there is no limitation in recovering the file items. After retrieving the items, you can save them in a new PST file. This PST file can be imported to any new Outlook profile.
