No. The Office 365 licenses are for your personal use on up to 5 of your personal computers and devices. University-owned computers have their own separate licenses which are installed and managed by your IT support staff. The on-line version of Office 365 can be used in addition to your 5 downloadable licenses and can be used from any personal or work computer.

 Office 365 is being introduced to provide more options, including free Office software.

If you have locked yourself out of your O365 account you can use your recovery options to regain access.  Step one will be to use the recovery option "I forgot my password" to set a new password.  After you set a new password, perform the recovery options for a second time, this time using the option "I know my password, but still can't sign in".  Recovery options can be found on the portal.office.com site by entering your SDSUid and then clicking "Can't access your account?".

SDSU does not share your recovery options with anyone and they are not visible to others. Recovery options are used by the Office 365/SDSUid system to help you gain access to your account in the event you should forget your password.

Impact of changing a username

Source: https://support.google.com/a/answer/2622985?hl=en


When you change a user's primary email address, G Suite retains the old address as an email alias for the user, to ensure continuous email delivery. Messages the user sends to their old address do not appear in the Inbox.

  •  Users retain access to all email received under the previous name.
  •  Users need to create new Gmail signatures for their new primary email address.
  •  Users don't receive any returned read receipts for messages sent from the old address.
  •  Users need to update their Gmail filters to use the new primary email address.


  • Events created before the rename show the old address while new events display the new address.
  • All secondary calendars (any additional calendars created by a user) will continue to display the original primary domain name.
  • If the original primary domain (which becomes a secondary domain following the rename) is deleted, all secondary calendars and associated events are also deleted and can't be recovered.
  • All video call links to existing events (including recurring events) will include the old domain name. You cannot attend by clicking on the link. This is also true with email reminders and change notification emails. Events created after the change will display the new domain in the video call link.


  • The renamed user's domain profile gains the new username but displays the old username with a custom tag appended to it: Obsolete
  • For other users, the contact entry for the renamed user displays both the new email address and the old one. The old one will be marked with the same custom tag: Obsolete
  • The old email address will still show up in autocomplete results, as it is now an alias of the changed account. Emails sent to the old address will be delivered to the new one.


  • All documents become owned by the new username.
  • Mobile devices, sync tools, and IMAP connections
  • The effects depend upon the behavior of the client. If the client lets you update the login for the account, your access to G Suite should continue. If the client doesn't let you change your login, you'll need to delete the old account and add a new one with the new name.

G Suite Sync for Microsoft® Outlook®

  • If you change a user's username, the user must create a new profile. G Suite Sync is not supported by the ETCS Help Desk.  For support creating a new profile, see your local technical support  within your college or department.  Google/G Suite Help's support article details how to create a new profile here:  https://support.google.com/a/users/answer/160659?hl=en

G Suite Classic Sites

  • Classic sites will not display in the browse all sites area.  Navigate to https://sites.google.com/a/mail.sdsu.edu to see these sites.  Once there, the site owner can copy the site so that it will display when browsed.  Please follow the Google support article for changing your web address here: https://support.google.com/sites/answer/98081?hl=en

Faculty, staff, and volunteers use G Suite for collaboration.  Employees of Aztec Shops, Student Health Services and  Interwork use other services for collaboration.  For questions related to other email services, please contact your local technical support representative.
