Using Office 365 retention policies with Office 365 Groups
TonyRedmond Hello Can I have a question related to this topic? I was searching information about what exactly is covered by retention policy targeted to Office 365 groups. And how it interacts with Sharepoint retention policy and Teams chat retention policies. But I didn`t find something useful. I understood, that Chats and team conversations can be retained only by Temas retention policy. But I`m not sure what is retained if we have additional Office 365 Groups retention policy retaining content for 1 year. I read an MSFT article where was mentioned that O365 groups retention police retain groups mailbox, files and conversations. But, The conversation should be part of Teams retention policy and this is where I`m quite confused.
I know that my question is quite complex, but I will appreciate even some forward to related sites.
Thanks a lot,
Miroslav
1. The only data covered by retention policies assigned to Office 365 Groups are the conversations in the group mailbox and the documents in the site belonging to the groups.
2. You need separate policies to cover other SharePoint sites (not connected to groups). Likewise, you need separate policies to deal with Teams chat and channel conversations.
3. The same policy can cover Office 365 Groups (Microsoft 365 Groups) and SharePoint. It can't cover Teams.

TonyRedmond Apologies for resurrecting this from so long ago - but I'm seeing behaviour in multiple tenants that leads me to question whether that is still the case.
Namely - that a retention policy applied only to a single Microsoft 365 group (and not applied to any SharePoint sites)...
...appears to block deletion of the group connected SharePoint site:
The behaviour when trying to delete non-empty folders from the SharePoint site also indicates a retention policy is in effect:
I will raise through the normal support channels, but if you are able to impart any wisdom, I would be grateful!
- The simple answer is that the retention policy applied to Microsoft 365 Groups covers the group mailbox and the SharePoint Online site (see https://docs.microsoft.com/en-us/microsoft-365/solutions/groups-teams-compliance-governance?view=o365-worldwide#information-retention). What you're seeing is as expected. The retention policies applied to SharePoint sites are for non-group connected sites.
