        Hi,
do you use evolution-ews or EWS through DavMail? I ask, because it
makes a big difference. The evolution-ews talks to the Exchange server
directly. It had an off-by-one hour error(s) too, the 3.38.2 should
contain all the current changes in this regard.

Right, it can be due to the time zone. I suppose your example:

>      TZID=3DAmerica/New_York:20201216T100000

reflects the expected time, at 10AM of the America/New_York time zone,
right? If yes, I'm afraid the Exchange server doesn't like "expanded"
timezone definition. Some servers do that. There used to be an option
in libical to "not use exact timezones", but it's gone for some time
now.

The evolution-ews doesn't pass libical timezones into the server, thus
maybe give it a try, if it's not used by you yet.
