Manually Migrate UW Deskmail email messages to UW Exchange Online (UW Office 365) (Mac)

Note: Manual email migration is a fairly complex technical process. UW-IT does not offer support for manual migration. If you are moving from one UW email service to an alternative UW email service, UW-IT strongly encourages the use of our Comparex supported migration service. Engaging Comparex results in a seamless email migration experience for users and local IT support staff. At $25 per email account, the charge for this service is far less than the cost of user personal time and/or local IT support staff time required for a more manual method of email migration. A UW budget is required for Comparex supported migration. See the UW-IT Comparex webpage for more details.

Complete all of the steps below to manually copy all of the emails from a UW Deskmail account directly into a corresponding UW Exchange Online (UW Office 365) email account. You can use this guide to copy all of the emails from a personal UW Deskmail account into a corresponding personal UW Exchange Online (UW Office 365), or from a Shared UW NetID UW Deskmail account into a corresponding Shared UW NetID UW Exchange Online (UW Office 365) account.

  11. On the left side of the Mail app, in the Mailboxes pane, under the name Uw, you will see the UW Deskmail account. The Mail app is now downloading all of the mail in the UW Deskmail account to your Mac, which may take up to several hours, depending on the amount of mail in your account. If you are a long-time user of UW Deskmail and have several years of email, you may want to let the Mail app sit for several hours. At the bottom of the Mailboxes pane, you may see a Downloading Messages message with the current status. When this message is no longer present, proceed to the next step.
  12. Once the Mail app appears to be finished downloading your UW Deskmail email messages, at the top of the screen in the Apple menu bar, click Mailbox, then click Synchronize All Accounts to confirm that all email messages have been downloaded.
  13. Now, you will see a “mail” folder in the Uw account. Expand that folder by clicking the arrow next to mail and you will see the UW Deskmail email folder structure and email messages you are familiar with.  However, you will not see the Uw Deskmail Inbox folder.
  14. The Uw Deskmail Inbox is actually nested under the Inbox folder at the top of the Mailboxes pane. To expand the Mailboxes Inbox folder, click the arrow directly next to Inbox and then you will see an Exchange (UW Exchange Online/UW Office 365) Inbox folder and a Uw (UW Deskmail) Inbox folder listed.

  2. You’ve just created a new email folder in the Exchange (UW Exchange Online/UW Office 365) account. Next you will copy email folders from the Uw (UW Deskmail) account to the new folder in the Exchange (UW Exchange Online/UW Office 365) account.
  3. PLEASE NOTE: Read this step all the way through before following the directions. Now, click and hold the “mail” folder in the Uw Deskmail account and, while continuing to hold the mouse button down, drag the folder into the UW Deskmail Migration folder in the Exchange (UW Exchange Online/UW Office 365) account. You can tell the UW Deskmail Migration folder is the destination folder when the text is white and the background is blue. You will also see a green + (plus) symbol appear to indicate that the Uw Deskmail “mail” folder is being copied into the Exchange (UW Exchange Online/UW Office 365) UW Deskmail Migration folder.
  4. Repeat this process with any other folders you’d like to copy from the Uw Deskmail account to the UW Exchange Online (UW Office 365) account, particularly any Sent, Sent Items, Deleted Items, and/or Trash, etc. folders that may exist outside of the “mail” folder.
  5. Next, click the Inbox folder at the top of the Mailboxes pane and click the Uw (Deskmail) Inbox.

At the top of the screen, in the Apple menu bar, click the Edit option, click Select All, then right-click any of the selected messages in the Uw (Deskmail) Inbox and select Copy to then select the UW Deskmail Migration folder, if you’d like to copy the entirety of the Uw Deskmail inbox to the UW Deskmail Migration folder.

  7. Depending on the amount of email messages being copied, this may take several hours to complete. We recommend you leave the Mail app open for several hours to ensure this process completes.
  8. At the top of the screen, in the Apple menu bar, click Mailbox, then click Synchronize All Accounts to confirm that all email messages have been copied.
