Customer is running Exchange 2013 with approx. 2500 mailboxes. When looking at calendars and sharing information through the availability service only the availability (free, busy or tentative) is shown. No details are shown by default.
Customer now request to publish more information so that users that want to schedule a meeting can see the details of other user’s appointments. This should not only be configured for existing users, but new users should receive this setting directly when provisioned.
For example, when configuring this for a user called Kim Akers (email@example.com) for all users you can use the following Exchange PowerShell command:
Set-MailboxFolderPermission kima:\Calendar -User Default -AccessRights Reviewer
When scheduling a meeting with Kim Akers I can now see her appointment details in Outlook, and I can open the appointment to see all details (read-only) of this appointment as shown in the following two screenshots:
Note. Check the Set-MailboxFolderPermission article on Microsoft TechNet for all details regarding the permissions that can be assigned.
