One off my users get an error message when trying to send a meeting request that includes any of my meeting rooms.
Error: Direct Booking
Test: Cannot directly book a resource for this meeting
It fails only for one user. Works fine for all other. I looked for any settings regarding security and permission on the meeting room, but there is nothing that should lead to this message.
We have tried the enable/disable "Exchanged Cached Mode"-fix without any success.
