Temporary Outlook Email

The Outlook application saves files on your hard drive when you open attachment files from an email. In order to do this, it looks in the registry to see if Outlook has already created a temporary folder (known as Outlook OLK). The file will be saved by Outlook and opened for you if it finds a registry entry for the OLK folder. A copy of the attachment is saved to the folder if the registry entry does not exist.

Following the troubleshooting steps below should resolve this error. Make sure that your Outlook profile is working properly after each step in order to resolve this issue.

Your Mailbox Has Been Temporarily Moved On Microsoft Exchange Server

The temporary mailbox for your mailbox has been moved to the Microsoft Exchange server. This mailbox will not have all the information that you used to have. However, you can still access it.”

You may also experience this error after migrating your mailbox to a new platform. In that case, you would need to rebuild your profile (step 3).

If you make any changes to your Outlook data, we strongly recommend backing it up first.

MS Outlook displays an error when trying to access an email account that says “Your mailbox has been temporarily moved to Microsoft Exchange server”. In addition, it explains how to restore mailbox items from Outlook data files (.OST) that are inaccessible or orphaned if manual workarounds cannot be applied.

If your primary mailbox has become disconnected from Outlook, Microsoft has provided some workaround methods.

Because of a corrupt Outlook profile, some messages may not be synchronized with the server and only live on the local computer.

Disable unnecessary add-ons

Outlook may not open due to unnecessary add-ons. If this is the case, users should disable them one by one and see if the account is able to be opened.
