Organizations often disable Azure AD accounts when users leave or for other reasons. What you might not know is that Teams then removes the account from membership of individual teams. A background process looks for disabled users and removes these accounts from team memberships. That doesn’t sound too bad, but what’s horrible is when you unblock an account. Teams takes a long time (at least 24 hours) to restore standard teams, it might not ever restore membership of org-wide teams, and private channel membership is removed too. It’s not a good situation.
The audit events generated for license assignments to user accounts available in the Azure AD audit log and Office 365 audit log are inconsistent and incomplete. This is certainly true for licenses assigned to accounts through auto-claim policies and group-based licensing, but known gaps exist in the audit records generated in other areas of Office 365 and Microsoft 365 functionality. We think Microsoft needs to pay attention to ensure that auditing works consistently and predictably across all workloads. Once they improve the fit and finish of audit record generation, they can move into other areas, like charging for access to high-value audit events.
