Read Gmail Messages on Microsoft Outlook

Login with Google Apps

The following instructions are for those who wish to access their TMU Gmail through their Microsoft Outlook Client. By using the Google Workspace Sync for Microsoft Outlook, you will be able to access all of your emails, calendar events, and contacts.


  • Sending large file attachments from outlook can take longer than with Google Workspace Sync.
  • IMAP only allows to send/receive emails. You will not have calendar or contacts synced with your Gmail account.
  • Google Workspace Sync allows you to use outlook to manage delegated accounts.
  • It’s very easy to set up. No ports or server addresses are needed.

You must already have Microsoft Outlook installed on your computer to proceed with the set up.

  • You can start sending and receiving emails from Microsoft Outlook right away, however we do not recommend changing your folder structure until the initial sync is completed. (Gmail status would indicate: ‘Initial download in progress’).
  • We also suggest not attempting to change your folder structure until your TMU migration is complete as this may interfere with the migration.
  • Also, some problems have been reported with deleting mail and finding sent mail. Check the folder mappings in Outlook and make sure that Outlook's "Deleted Items" is mapped to Gmail's "Trash" folder. The same goes for Outlook's "Sent Items". They must be mapped to Gmail's "Sent Mail" folder.
  • In case Google Workspace Sync results in a corruption of the stored passwords which forces Outlook offline, and halts synchronization, the following steps will correct the issue:
    • Close Outlook.
    • Navigate to the Google Apps Sync programme folder; usually found in either C:\Program Files (x86)\Google\Google Apps Sync or C:\Program Files\Google\Google Apps Sync
    • Run the application profilepassworddelete.exe that you will find there, select the appropriate account, then click on delete stored password.
    • Relaunch Outlook and put it back online (found in the send/receive tab on Outlook 2010/2013).
    • When prompted, sign into CAS. Remember to click on the Accept button that will appear at the bottom of the next page.
