How to Fix Mailbox Temporarily Moved Error on Microsoft Exchange Server in Windows 11

Encountering the “Mailbox Temporarily Moved” error on Microsoft Exchange Server can be frustrating, especially when working on Windows 11. This error usually indicates that your mailbox has been relocated to another database or server within the Exchange environment. Understanding how to resolve this issue promptly is crucial for maintaining smooth email operations.

In this article, we will guide you through simple and effective steps to fix this error. Each step is explained clearly, with the aim of helping even users with minimal technical experience.

By following these instructions, you can quickly restore access to your mailbox without requiring complex administrative tasks. Let’s begin with some quick notes before diving into the troubleshooting steps.

Remember, patience and careful execution of each step will lead to the best results.

Quick Note: Prerequisites and Initial Checks

  • Check your network connection: A stable internet or intranet connection is essential for Exchange Server communication.
  • Confirm Exchange Server status: Verify that the Exchange Server is online and accessible.
  • Ensure correct user credentials: Double-check your username and password to avoid simple authentication issues.
  • Check mailbox availability: Confirm whether your mailbox has recently been moved or migrated by your Exchange administrator.

Step 1: Restart Outlook and Reconnect

Sometimes, the error is temporary and caused by a brief communication glitch. Restarting Outlook and attempting to reconnect can often resolve the issue.

  1. Close Microsoft Outlook completely.
  2. Wait for about 30 seconds to allow all background processes to end.
  3. Reopen Outlook and see if the mailbox connects properly.

Why this helps: Restarting clears temporary cache and refreshes the connection to the Exchange Server, which may fix minor synchronization problems.

Step 2: Verify Outlook Profile Settings

Incorrect or outdated Outlook profile settings can cause mailbox connection errors. Checking and updating these settings ensures Outlook is pointing to the correct mailbox location.

  1. Open Control Panel on your Windows 11 PC.
  2. Search for and select Mail (Microsoft Outlook).
  3. Click on Show Profiles.
  4. Select your Outlook profile and click Properties.
  5. Click Email Accounts and verify the account settings.
  6. Ensure the server names, mailbox names, and connection types are correct.
  7. If unsure, remove and recreate the profile by clicking Add and configuring your email account again.

Why this matters: If the mailbox has been moved, your profile might still be pointing to the old server location, causing the error.

Step 3: Clear Outlook Cached Mode

Outlook’s Cached Exchange Mode stores a local copy of your mailbox. Sometimes, this cache becomes corrupted, triggering errors. Disabling and re-enabling Cached Mode can refresh your mailbox data.

  1. Open Outlook and go to File > Account Settings > Account Settings.
  2. Select your Exchange account and click Change.
  3. Uncheck the box that says Use Cached Exchange Mode.
  4. Click Next, then Finish, and restart Outlook.
  5. After Outlook restarts, repeat the steps and re-enable Cached Exchange Mode by checking the box again.

Why this works: Refreshing the cache forces Outlook to download a fresh copy of mailbox data aligned with the current Exchange Server location.

Step 4: Use Exchange Management Shell to Verify Mailbox Location

If you have administrative access, you can check the exact mailbox location using Exchange Management Shell commands. This helps confirm if the mailbox has moved and where it currently resides.

  1. Open Exchange Management Shell on the server.
  2. Run the following command, replacing user@example.com with the actual email address:
    3. Get-MailboxStatistics -Identity user@example.com | Format-List Database
  3. The output will show the database name where the mailbox is located.
  4. Compare this with the settings in Outlook or your Exchange Admin Center.

Why this step is important: It confirms the mailbox’s current location, which helps in troubleshooting and updating client settings accurately.

Step 5: Update Mailbox Database or Move Mailbox Back (Advanced)

If the mailbox was moved unintentionally or requires relocating back, an Exchange administrator can move the mailbox to the appropriate database.

  1. Open Exchange Admin Center or use the Exchange Management Shell.
  2. To move a mailbox using PowerShell, run:
    3. New-MoveRequest -Identity user@example.com -TargetDatabase "CorrectDatabase"
  3. Monitor the move request status:
    4. Get-MoveRequestStatistics -Identity user@example.com
  4. Once completed, verify mailbox accessibility in Outlook.

Note: This step requires Exchange admin privileges and should be done carefully to avoid data loss.

Alternative Method: Recreate Outlook OST File

If mailbox errors persist, deleting and recreating the Offline Storage Table (.ost) file can fix corrupted local data.

  1. Close Outlook.
  2. Navigate to the OST file location, usually at:
    3. C:UsersYourUserNameAppDataLocalMicrosoftOutlook
  3. Find the .ost file associated with your mailbox and delete it.
  4. Restart Outlook; it will recreate the OST file and synchronize mailbox data fresh from the server.
