While examining mailbox properties, I noticed that the EnforcedTimeStamps property held some information that I just couldn’t explain. Google search was no help, but Microsoft Copilot told me that the information related to the management of compliance holds. Basically, the data are guardrails to help the Managed Folder Assistant do the right thing, which is nice, even if no documentation exists.
Microsoft has moved retention processing for SharePoint Online, OneDrive for Business, Teams, and Yammer from the Managed Folder Assistant to a new retention assistant. (background processing job). It’s part of an effort to use workload-agnostic processing whenever possible to perform retention actions across Microsoft 365.
The Exchange Online Managed Folder Assistant (MFA) runs in the background on a workcycle basis to make sure that mailboxes are processed at least once a week. Most of the processing involves mailbox and Office 365 retention policies and runs smoothly, but how do you know what MFA has done?
A question asks how to remove a bunch of emails from a shared mailbox. You can use OWA to do the job, especially with its Cleanup Mailbox option, but perhaps some administrative action is needed.
