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!
Hey,
Figured it out. The update modified my Free/Busy permissions. Read permissions were set to "None.
