Free / Busy Build 7870.2020

Just thought I would let you know... Users are unable to view my Free/Busy information. Outlook is stating they do not have permission to view my availability. I'm the only person in the organization...

We have been struggling with this for quite some time as well. On premises mail users were not able ot view free/busy information for a user who has their mailbox in EXO. After opening a ticket the MS support, it turned out our Exchange 2010 servers did not have the DigiCert root required for outlook.office365.com. After deploying this root cert to our Exchange on premises, we are now able to view free/busy!

Can you elaborate a bit on your fix? I am worried I have this problem as well.

  Yeah sure, after the update was applied it modified primary calendar permission settings. Read permissions were set to "None."
  
  Go to Calendar and right click on your primary calendar. Select Properites > Permissions. Make sure the Read permission is set to "Free/Busy time."
