Preconfigure Exchange account on Gmail

From your admin console, go to the Policies tab and edit the policy you want to work on (or create a new one). Make sure the Gmail app is approved company-wide. Click on the  icon in the top right corner of the Gmail app and select Configuration.

From here, follow the configuration template below:

  • Put the token $emailaddress$ in the field email address
  • Put outlook.office365.com in the field exchange server url (if this is an Office 365 Exchange server account)
  • Put the token $emailaddress$ in the field username (only if the Exchange user name is the same as the email address. If not, you can put the token $directoryname$ after making sure the directory name set for each user corresponds to their Exchange user name)
  • Make sure that SSL Required is activated
  • Set the Sync time window (0 = synchronize all items; 1 = 1 day; 2 = 3 days; 3 = 1 week; 4 = 2 weeks; 5 = 1 month)
  • Click on SAVE
