Awareness – Is Your Federation Trust Metadata Updated?
Imagine the scenario — all is working well with your Office 365 hybrid solution until you come into the office tomorrow morning and you get calls saying on-premises users are unable to see the free/busy information for mailboxes in Office 365.

Exchange and AntiVirus Exclusions – Still A Critical Conversation
