Error “No free/busy information could be retrieved” for one user

We try to add “User1” to a meeting request in OWA/Outlook 2010 but couldn’t view his free busy information. It errors stating “No information could be retrieved”. Everyone getting same error for User1 but User1 can view his free/busy from Outlook.

Test-OutlookWebservices was success. Autodiscover working fine and can set Out of Office.


Since the issue is for one particular user, check for the calendar permission of the user by running following command:

Get-MailboxFolerPermission -Identity User:\calendar | FL


If the default permission is set to none, change it using the following command:

Set-MailboxFolderPermission -Identity User:\calendar -User Default -AccessRights AvailabilityOnly
