Meeting room mailbox not showing details - Show Full Free/Busy Details for MS Exchange Server Room and Resource Mailboxes

Issue

There is a room/Resource Mailboxes, that is not showing any details when booking it. It shows only created person name or free/busy status.

For e.g, check below image.

Cause:

This is caused by the default permission on the mailbox's calendar. This mailbox permission set either AvailabilityOnly or Show only. So this permission needs to be changed.


Solution

1. Open MS Exchange PowerShell and check permission for this mailbox calendar

PS cmd:

Get-MailboxFolderPermission <Mailbox_Name>:\Calendar
If the result like below,
FolderName User AccessRights SharingPermissionFlags
---------- ---- ------------ ----------------------
Calendar Default {AvailabilityOnly}
Calendar Anonymous {None

2. Then change the Access Rights to Reviewer or other permissions as per your requirements.

PS cmd:

Set-MailboxFolderPermission -Identity <Mailbox_Name>:\Calendar' -User Default -AccessRights Reviewer
3. Now you can check permission using above same cmd.
