Move Microsoft 365 Email on Windows Mail app
This guide instructs users on how to transfer emails from one Microsoft 365 email inbox to another Microsoft 365 email inbox.
This guide starts with both email inboxes already set up in the Windows Mail App.
Please check the Windows Mail setup guide for steps on setting this up first.
Update: Newer versions of Windows Mail no longer support the drag & drop functionality. We recommend downloading and using the Outlook app if your Windows Mail app has been recently updated and drag & drop no longer works.
You can read our guide on how to migrate your mail in the Windows Outlook app instead.
We recommend making a backup file of your emails before starting the migration. This can not be done on Windows Mail, so we recommend installing the Windows Outlook app, and then please follow the steps on how to backup your emails from Microsoft.
With the Windows Mail app open, select the emails from the inbox that you would like transferred
To select multiple emails, hold the control key and click on the emails you would like, selected emails will be highlighted in light blue
You may want to transfer emails in batches if you have a large inbox.
Click on the first email you want, then holding <shift>, select the last email you would like. This selects all of the emails in-between the first and last so that you can transfer in a batch.
2. You can now drag and drop the emails into the inbox you would like.
3. Do not close Windows Mail yet. You MUST verify online that the transfer was successful by visiting office.com. Failure to follow this step may result in a loss of emails.
a. Sign in with the email account you want the emails to end up in with username@uwaterloo.ca to check for the email
