Office 365 groups going CRAZY

[synaesthesia]

I may be going crazy, it may be 365, I don't know.

We have groups in AD for our year of entries - Entry 2020 is year 7 up to Entry 2014 for Year 13. Each has an email address, [email protected], [email protected] etc etc. This all syncs, usually, hunky-dory with Office 365 via AzureAD Connect when we bump them up a year.

But not this year. It's gone a little big special.

No, seriously... Search our groups in 365 for "year 7" and it shows up just exactly as it should:

But wait, there's more!

The very moment you click it to inspect contents.... BANG! It changes to this gobbledegook!

And to top it off, year 8 is actually year 9, year 9 is actually year 10 etc as if they haven't or won't update.

Sync status says everything is perfectly fine! No duplicates or cockups in AD!

I have never seen anything like it. If I search for that random looking group name, it doesn't show, either in 365 or local AD.

 

Any clues?

Sounds like you have group writeback turned on, as Group_ is when AADC uses by default, guessing maybe it's getting out of sync between AD->Cloud->AD? Have you tried disabling writeback temporary?

Writeback isn't enabled. Also oddly, AzureAD seems fine!
