UWin Gmail to Office 365 Outlook Transition

IT Services is upgrading student e-mail accounts (UWinID@uwindsor.ca) from UWin Gmail to Outlook starting January 2020. 

 The University of Windsor is investing in this upgrade to provide students with:   

  • the same e-mail platform as faculty and staff, facilitating easier collaboration within the campus community   
  • an integrated system with communication, creation and collaboration tools in one place  
  • more secure e-mail  

IT Services will pilot the Outlook upgrade with incoming Winter 2020 undergraduate students who have no previous student relationship with UWindsor. In addition, starting mid-January, students who accept offers of admission for future semesters will also use Outlook for their student e-mail accounts instead of UWin Gmail. 

All other students will continue to use their student e-mail accounts in UWin Gmail until summer 2020 when the upgrade of all student email accounts is scheduled to occur. Alumni accounts will be migrated after Sept 2020.
Students will be able to access both Outlook and UWin Gmail at www.uwindsor.ca/studentemail

Please note: there will be no change to UWinID@uwindsor.ca email addresses. It is only the tool students use for their email that is changing. 

What Will Be Migrated

As part of the UWin Gmail to Office 365 Outlook Migration, the following items in your UWin Gmail account will be migrated to Outlook and OneDrive:

  • Mail Messages
  • Calendar Entries
  • Contacts (maximum of three addresses per contact)
  • Files stored in your Google Drive

What Will Not Be Migrated

Due to the technical limitations, the following will not be migrated:


  • Vacation Settings or Automatic reply settings as well as Filters or Rules


  • Shared calendars, cloud attachments, Google Hangout links and event colors


  • A maximum of three e-mail addresses per contact are migrated over
  • Gmail tags, contact URLs and custom tags are not migrated over


  • Sharing Links will not be migrated.  You will need to reshare any files from OneDrive after migration.
  • File versions will not be migrated - only the most recent version of the file will be migrated to OneDrive
  • Google does not allow us to export Drawings, Forms, Sites, and Maps from Drive. These will not be transferred.
  • Google Docs, Slides and Sheets:  Google's proprietary formats are not compatible with anything other than G Suite Drive. When migrating from G Suite, Docs, Slides and Sheets will convert to the Microsoft Office format
  • Any Google Doc, Slide or Sheet larger than 10MB will not migrate.  You will need to download and move any of these files over manually.
  • Any files marked as restricted will not migrate over

Gmail Labels vs. Outlook Mail Folders

Mail on Office 365 doesn't support labels. How is mail translated to folders? In order to provide the best mail experience in Outlook as well as account for the Focused/Other view, we translate most labels to folders. 

  • Mail with the 'Starred' label will become flagged.
  • Mail with the 'Important' label will influence its Focused/Other designation.
  • Mail with other labels will be copied into a folder with the corresponding label name.
  • Mail with no other labels will be moved to the Archive folder.

This means that some items that had multiple flags in GMail will appear in multiple folders in Office 365.
