Moodle is integrated with M365. The Teams sync process creates Class Teams for some of our courses with Teachers as owners and students as members.

Recently our Moodle logins were changed from user's UserPrincipalName (numerical IDs) to their shortname. Two accounts now exist for instructors: accounts with shortname as the primary ID and the old accounts with numerical IDs. After this change took place, the first new users with a shortname in the system did not correctly sync into their Teams course as an owner. I am unable to switch the integration to use the new accounts to sync owners. We have attempted to delete the old accounts to use the new ones to no avail.To clarify further, the 2 accounts exist after we switched our Moodle Logins to SAML (plugin: auth_saml2).
We also had an issue of a user syncing into the wrong course after this change.
