Adding a Disclaimer to Calendar Meeting Requests

Exchange transport rules are a powerful way to apply different conditions to messages as they pass through the transport service.

New Teams Files Channel Tab Finally Rolling Out

After a long delay, Microsoft has started to deploy the new Teams Files channel tab experience to Office 365 tenants.
