One of the most awesome preview features today for Office 365 is the ability to set an expiration policy for the Office 365 Groups. Cleaning up old and unused content is something all organizations want, but people are inherently afraid of deleting content and thus become document hoarders. I truly believe this feature might help organizations finally rid themselves of old crap cluttering up all the good stuff.
Note: Groups expiration policy is a premium feature requiring all users in affected groups to have an Azure AD Premium license, and in my opinion this might be a good reason to invest AAD premium.
Currently each tenant support one expiration policy, and you have to decide if this policy should apply to all Office 365 Groups or only to a select number. I expect more policies to be possible in the long run, but one step at a time.
If you opt-in to include all Office 365 Groups in the expiration policy you are in the clear, and really don’t have to read the rest as it’s all automated for you :)
