Installing Outlook Update KB2878264
As some affected users have pointed out, this problem can also be caused in scenarios where the Outlook update KB2878264 is not installed on the Outlook machine. This only applies to users who encounter the error “Your mailbox has been temporarily moved to the Microsoft Exchange server” with Outlook 2010.
It turns out that Microsoft has already released a patch for this problem (KB2878264, pushed by Windows Update).
The WU component should have automatically installed it on your machine in case you did not take steps to prevent the installation of new updates for your operating system.
Rename the Outlook folder
It turns out that the error “Your mailbox has been temporarily moved to the Microsoft Exchange server” may also occur due to corrupted data in the main AppData folder of the Outlook application.
Some users facing the same problem have managed to solve it by accessing the AppData folder and renaming the existing Outlook folder to force the application to create a new folder. This operation will also avoid having to deal with a loss of data if the operation fails.
