Historical Email Migration from Webmail to MUNmail

Nov 5th, 2026

Information for users who have transitioned from the Webmail platform to MUNmail (Google Workspace)

OCIO has begun migrating historical email for users who previously used the Webmail platform and have since transitioned to MUNmail (Google Workspace).

Please note that historical email may take several days to appear in MUNmail after migration begins. During this time, messages may gradually populate as they are processed and imported into Google Workspace.

As historical messages are imported, you may notice some differences in how email is organized or displayed. These changes are expected and result from how Google Workspace and email applications process migrated email.

You may notice the following:

  • Folders become labels. Email folders from Webmail are converted to Gmail labels during the migration process.

  • Some unread messages may appear as read. In some cases, read/unread status may not transfer exactly as it appeared in Webmail.

  • Message dates and times may appear differently. Depending on the email application you use, some messages may display the date and time they were received by Google Workspace during migration rather than the original date and time they were received in Webmail.

  • Display may vary by email application. Gmail, Outlook, Apple Mail, and mobile mail applications may present migrated messages differently based on their own design and settings.

Please note: These behaviours are expected when historical email is migrated from Webmail to MUNmail. They do not indicate a problem with your migration and are the result of how Google Workspace and email applications handle migrated email. As such, these behaviours generally do not require corrective action by OCIO.

If you experience issues beyond those described above, please contact the OCIO Service Desk.
