Hi @Glenn Maxwell ,
Welcome to the Microsoft Q&A platform!
Let me answer your questions one by one:
- When you enable the IsGroupFoldersAndRulesEnabled setting using the command Set-OrganizationConfig -IsGroupFoldersAndRulesEnabled $true, it specifically allows users to create folders and rules in the unified group mailbox. This setting does not affect other features of the unified group. It is focused only on enabling folder and rule management in the group mailbox.
- Yes, retention tags and policies can be created for unified group mailboxes. You can manage these through the Exchange Admin Center (EAC) or by using PowerShell commands. Retention policies help manage emails and other items in a mailbox by automatically archiving or deleting them through their lifecycle based on defined policies.
- Users can create folders in the unified group mailbox and move emails just like in a regular mailbox. Once the IsGroupFoldersAndRulesEnabled setting is enabled, group owners (and members if permissions are granted) can create, rename, and move messages between folders.
Please feel free to contact me for any updates. And if this helps, don't forget to mark it as an answer.
Best,
Jake Zhang
