Error: 'No free/busy information could be retrieved' when trying to open calendar in Outlook Scheduling Assistant (applies to only one user)
I get: 'No free/busy information could be retrieved' when trying to resolve a certain user's name to open his calendar in Outlook Scheduling Assistant.
The username gets only resolved when I type in the entire E-MAIL ADDRESS OR the SURNAME of the user but NOT the first name!
All other user user calendars resolve fine by typing in any part of their usernames (from their first or the last names).
I have checked the AD and mailbox properties of that account and it seems to be identical to all other accounts.
