It may take some time for the transfer to complete depending on the amount of emails are being transferred. You can view your inbox in the Outlook app to confirm the emails were transferred, however please do not close Outlook until you have verified online that the transfer was successfully completed and sync'd to the online server by visiting microsoft365.com. Failure to follow this step may result in a loss of emails.

Sign in using the email account you would like the emails to end up in.

 

Transferring the entire inbox

Drag the inbox that you would like transferred to the inbox you would like to move it to. For example, drag the inbox of your second account to the first account inbox. It will become a folder under your new inbox.

You can rename this folder based on your preference. If you do not see the subfolder, try clicking on the arrow beside the inbox.

 Note: The drag and drop feature is available to the previous Outlook version. To switch to the previous Outlook version click on “new Outlook” switch located on the upper right corner:

Once you are finished transferring your files over to your new inbox, you can click on the ‘New Outlook’ switch located on the upper right corner to switch back to the newer version.
