Hi Derek,
Thanks for your feedback.
I would find it logical if it worked as described in the official Smartermail instructions. I understand that there are different permissions for the room resources? Unfortunately, that's not the case; not even the manager can manage anything. It should only be handled similarly to a user calendar, in terms of permissions.
The many claims that Smartermail is a powerful Exchange alternative are unfortunately untrue due to the lack of basic standard features.
So, if I understand correctly, I've now invested countless hours of work in migrating our customers to Smartermail (which I can't charge them for), spent a lot of money on Smartermail licenses, have very dissatisfied customers because practically nothing works properly, and now I have to send the customers to the Microsoft Cloud so that they can use basic Exchange functions again?
