How to Fix ‘Your Mailbox Has Been Temporarily Moved’ Error?

Some Office 365 users are reporting that they always see the ‘Your mailbox has been temporarily moved on Microsoft Exchange server‘ error whenever they try to use Microsoft Outlook to manage their email addresses. Affected users are reporting that the error message returns the next time they attempt to start Microsoft Outlook regardless of what they choose at the prompt (Use Temporary Mailbox or Use Old Data).

Your Mailbox has been temporarily moved error

If you’re encountering this issue, the first thing you should do is remove any complementary Outlook profile that is stored alongside your active one in order to avoid any conflicts. If that doesn’t work, you should proceed by removing every Outlook profile that’s stored locally and create a new one from scratch that uses the same email account.

If you’re using an MS Exchange account, you should be able to fix the error prompt by accessing your email settings and enabling the Use Cached Exchange Mode option from Offline Settings. Renaming the current Outlook profile in order to force the program to create a new instance can also fix the issue if the problem occurs due to some corrupted temporary files.

In case you’re encountering the issue with Outlook 2010, you might see this error due to the fact that the KB2878264 update is not installed on your computer (Method 3 will show you how to install it manually).

However, if you’re seeing the ‘Your mailbox has been temporarily moved on Microsoft Exchange server‘ error with Outlook 2013 on Windows 10, you might need to do some registry tweaks in order to accommodate Mod auth.

Method 1: Remove any other Outlook profile

As it turns out, one of the most common causes that will trigger the ‘Your mailbox has been temporarily moved on Microsoft Exchange server‘ error is a conflict with one of the other Outlook profiles that are being stored locally.

Some affected users have managed to resolve the issue by removing every Outlook profile except for the user’s primary profile. But before you go through with this, keep in mind that when you remove a profile in Outlook, every bit of data for that associated account will also be removed.

To ensure that you’re not losing any important data, make sure to back up any information that you need (unless the data is also stored on the server or you are sure that you have no use for the data).

Note: If you want to backup your data, go to File (ribbon-bar at the top) > Open & Export > Import / Export > Export to a file, choose Outlook Data File (.pst) and hit Next to complete the operation.

After you’ve made sure that you backed up you. PST file or you are certain that you don’t need it, follow the instructions below to remove any other Outlook profile that’s not the primary one:

  1. Close Outlook and any associated instances.
  2. Press Windows key + R to open up a Run dialog box. Next, type ‘control’ inside the text box and press Enter to open up the classic Control Panel interface.

  8. Once every Outlook profile has been removed (except the primary profile), click Ok in the Mail dialog box to close the window.

    Show Profiles in Mail Setup

    Enabling Cached Exchange Mode

    Note: If the option is already enabled, disable it, save the change, enable it again and restart Outlook.

  7. Restart Outlook and see if the issue is resolved at the application startup.

Method 5: Renaming the Outlook folder

As it turns out, the ‘Your mailbox has been temporarily moved on Microsoft Exchange server‘ error can also occur due to some corrupted data present in the main AppData folder of the Outlook application.

Some users facing the same issue have managed to get the problem fixed by accessing the AppData folder and renaming the existing Outlook folder in order to force the application to create a fresh folder. This operation will also ensure that you don’t have to deal with any data loss in case the operation is not successful.

  1. Press Windows key + R to open up a Run dialog box. Next, type ‘%appdata%’ and press Enter to open up the AppData folder on your computer.

    Note: Keep in mind that this folder is hidden by default.
