Hello Team, We have user in our environment, we are not able to view his free busy information. It is giving error "No free/busy information could be retrieved from the server." We have checked in OWA as well it is same. We ran the below cmd to check the permissions and it is correct. Get-MailboxFolderPermission -Identity XXXX:\Calendar FolderName User AccessRights SharingPermissionFlags

Calendar Default {AvailabilityOnly}
Calendar Anonymous {None}
Can you let us know how to proceed.

Hello @Alka Kumari ,

Have you tried turning off Cached Exchange Mode? If possible, you could try turning off Cached Exchange Mode and restart Outlook.Besides, it is recommended that you restart the Microsoft Exchange Mailbox Assistant service on the Exchange server and try again.

If the problem persists, deleting the Office credentials saved in Credential Manager may also be a method worth trying.

Hope the above information is helpful to you！

Hello Brianna, I have checked on the online mode and getting the same error. It is only for that specific user we are not able to view his free/busy information. I asked my colleague as well to check on his end and he is also getting the same error. I thought of checking if the mailbox is hide from GAL or not. But it is also not hide in GAL. Any other thing that we can try?

Sorry for the late reply, I have been away from work the past few days due to vacation :) There are many possible reasons for this problem. I konw You have checked Exchange online mode but still have problems. In order to further solve the problem, it is recommended that you try to check whether auto-discover is working properly or change the calendar permissions.
