By default, Exchange Online allows other users in your tenant to see limited details of your availability when scheduling meetings. More information can be displayed by updating the calendar permissions for mailboxes. This is easy to do with PowerShell, but needs to be done on an ongoing basis because Exchange Online doesn’t have an organization or mailbox plan setting to assign the value to new mailboxes.
Exchange Online’s calendar assistant is good at responding to meeting requests for rooms. It can be even better with just a little customized text to remind those who book the rooms about meeting etiquette. Even though we might never get back to physical meetings in conference rooms, some face to face gathering will happen in the future, so now’s the time to prepare for bookings to be handled in a nicer fashion.
Unlike email systems, Microsoft Teams doesn’t support user delegation, or assigning the right for someone to act on behafl of someone else. Here’s how to workaround some of the issues involved in helping managers and their assistants work effectively together, including personal chat, channel messages, and scheduling calendar meetings.
