Serverless Computing is an interesting concept. You can execute a script or programm without setting up the infrastructure behind it (servers, storage, networks, etc.). You just write your code and it gets executed. But Serverless doesn’t mean “without any servers” - you just don’t need to worry about them.

By default, the “Calendar” folder in Exchange 2013 Room Mailboxes has the “LimitedDetails” permission for the “Standard” security principal. Therefore, if no other permissions are configured, users cannot view details for appointments in this room. For better usability in Outlook, the “Reviewer” permission is more suitable. This allows items to be listed and details to be displayed. If required, the CalendarProcessing can be adjusted so that details such as the description and subject of the appointment are not saved in the room mailbox....

Outlook Certificate Warning after Office 365 Migration Security Alert: svr1.example.com The security certificate has expired or is not valid yet I recently received a request from a customer who still received certificate warnings (expired certificate) for the old Exchange Server after migrating to Office 365.
