SharePoint Online Auth Failures - Modern Auth Backups Likely Impacted


Userlevel 7
Badge +8

Hi, Microsoft have a service alert for SharePoint Online.

 

If you’re doing everything right, odds are you’re using modern auth for your Microsoft 365 backups, in which case, you’re using the Graph API.

 

In this scenario, you may find you’re getting “Access Denied” errors in your backups, or even in your BAU processes.

 

If so you want to check out SP381039.

 

The latest information is some authentication components are missing for certain environments causing the failure. Microsoft are redeploying these components, no ETA as yet.

If I get any further service notifications on this I’ll post back here. Microsoft haven’t provided any details on if this impacts any specific regions either, so the spread of impact is still unknown.
