No scheduling assistant available
Your environment
TbSync version: 4.7 Thunderbird version: 102.13.0 Server: MS-Exchange, version unknown
Expected behavior
When I schedule a meeting, I see other peoples free and busy times, if they are on the same server.
Actual behavior
I do not see other peoples busy times, it looks like nobody had any appointments.
Steps to reproduce
Schedule a meeting with people on the same server, who already have some busy time slots.
Note
I believe, that this feature used to work with calendar-exchange-provider back than, but I'm not sure.
The same behavior at Thunderbird 115.6.0 (32-bit), TbSync 4.8, Provider for Exchange ActiveSync 4.8, Exchange Server 2013. It's a frustrating lack of functionality for teamwork.
That is not supported and I do not have the resources to implement that feature.
