Convert existing O365 groups from one domain to another without issues / problems
Hi nostalgic
Considering your AAD Connect, are your Office 365 groups synced to local AD or are they cloud only? I find most Office 365 groups are cloud only even though the users are synced with AAD
If Cloud only, and assuming that the second domain is validated within the 365 tenant then the following article should work for you.

As always would recommend testing on a test group to ensure that it works before doing it on live groups.
Let me know how you get on - or if the groups are synced from local AD.

- Hi nostalgic,
Just want to double check - the Office 365 groups are synced back to Local AD using the writeback feature and your organisation is in Hybrid. See article
https://docs.microsoft.com/en-us/exchange/hybrid-deployment/set-up-office-365-groups
Just want to be 100% sure before making the recommendation!

Hi Chris,
I have checked the AAD Connect configuration and all the " write back " features are disabled.
The AAD Connect client does have the attribute " groups " selected when running a sync my understanding is that because of this - the groups are synced to O365.
To my understand I would need to modify the attributes of the groups on local AD but I'm not sure if I can change the domain in the group properties and if that would have bad side effect on Teams.
The domain we want to change it to is verified in O365.
Looking forward to your reply.
- Hi nostalgic
It is difficult to say without looking at this in your tenant and as Adam says there are several different types of groups - could be distribution lists syncing to your Office 365 tenant not actual Office 365 groups
A good way to check is this - can you go into the Microsoft 365 Admin Centre (https://admin.microsoft.com) and go to Admin > Groups > Groups. Are the groups which are Office 365 groups also groups on your local AD and in an OU which is syncing via Azure AD Connect? If they are not present in any of the OU's which are syncing then this means that they were created in the 365 Tenant.
Let us know how you get on.
Best, Chris
