I have hybrid Exchange in company A (exchange 2016). I have created sharing calendar information beetween company A and company B. From company A I can check the availability of calendars of people from company B, but not all of them. From Outlook in Windows, when I try to check availability callendar of some people from company B, I receive no information. For all the people I add after these people (even from company A), I no longer receive information about the availability of the calendar. Once I remove the problematic person, I can check other people’s calendars.

The problem does not occur from Outlook on the Web or from MS Teams or NewOutlook – everything is OK. The problem only occurs with Outlook on Windows (version 365). How to solve the problem with checking calendar availability from Outlook in Windows?
