Office 365 Activity Alerts don’t seem to be working too well these days. At least, that’s what we found when we tried to create an alert for Teams creation events. Never mind, PowerShell will do the job as we can quickly whip up a PowerShell script to find audit records for team creations and put them into an email.
Exchange Online writes audit records into the Office 365 audit log when messages are deleted by delegates and administrative action. We can analyze the audit records to find out who deleted a specific message. Some challenges exist to interpret the audit records for admin-generated deletions (for example, when you run Search-Mailbox), but it’s easy enough to code the necessary checks in PowerShell.
On May 7, Microsoft eventually fixed a truncation bug that affected group events (creation, add member, etc.) ingested into the Office 365 audit log. The fix took far too long coming and the overall response is certainly not Microsoft’s finest hour. Audit events, after all, are pretty important in compliance scenarios and it’s not good when those events are incomplete.
The modern SharePoint Admin Center introduces the ability to rename the URLs for SharePoint site names. This responds to a longstanding customer request and makes it possible for site names to reflect what users see elsewhere in Office 365 groups or Teams. It’s a small but welcome change in the fit and finish category.
In one of those interesting (but possibly worthless) facts discovered about Office 365, we find that audit records are captured for Teams compliance records written into Exchange Online group mailboxes. The Search-UnifiedAuditLog cmdlet reveals details that we can interpret using some techniques explained in Chapter 21 of the Office 365 for IT Pros eBook.
