Move personal emails to a new account in Outlook

Note: Microsoft is updating their Microsoft 365 Outlook for Mac. As a result, some import/export functionality may not be available. Please see Microsoft's Import and export Outlook email, contacts, and calendar article for the latest on supported features.

To migrate personal emails from an address to an address (or any other email address) using Outlook, first make sure your email is added to Outlook. Please note that this cannot be done using the web version of Outlook, this can only be done in the desktop client.

Before exporting your emails, make sure that Outlook has downloaded the entire message history from the server by following these steps:


  1. In the upper left of the window, click on “File”, right above the “New Email” button.
    • If you do not see "File" in the top left Window, you may be in the newer version of the Outlook app, which does not currently support the option to export emails.
    • You may be able to revert Outlook to "classic Outlook", which does still have the correct functionality. Do this by selecting "Help" in the upper left, then "Go to Classic Outlook". 
    • Once in "Classic Outlook", follow the steps below. 
  2. Click on “Account Settings” and then “Account Settings” again.
  3. Select your account, if you have multiple accounts added to Outlook.
  4. Once the account is selected, click on the “Change…” button above the list of email accounts.
  5. Ensure that “Use Cached Exchange Mode” is checked, then drag the slider to the right until it says “all”
  6. Click “Next” and then “Finish”
  7. Close and restart Outlook
  8. You will then need to view each folder for Outlook to start downloading older messages. After your mailbox loads, you should verify all your emails are present when you view each respective folder.


  1. Click “Tools” in the top menu of the Outlook client.
  2. Click “Export” and then select the item types to export.
    • Note: If you do not see the Export button, make sure you have the latest version of Outlook. On the Outlook Help menu, click Check for Updates. If all Outlook updates are applied and you still don't see the Export button, look for Export on the Outlook File menu. If that still does not work, under the Help menu, select "Revert to Legacy" and then try again.
  3. Select the items you wish to export and then select a location (e.g. Desktop) to Export to.
  4. Click “Save”.


Once you have ensured that all messages have been downloaded, you may proceed to the next steps.
