[Evolution] Evolution Scheduling Issue.

[James Toebes <james toebesacademy com>]

Help Please!   I am using Evolution to schedule calendar events.
        Fedora 33
        Evolution 3.38.2 (3.38.2-1.fc33)
        DavMail
        EWS

When they are received by a person using Outlook,  The time is being 
shifted off by an hour.  Goggling shows this to be related to the 
Timezone in the invite.  Checking the timezones.  Server and client Time 
zones seem Ok/ Server and both sending receiving clients are all in US 
Eastern Time zone.  The raw message sent has tags that show Tags all 
have 3D after all the rqual signs.  The TZID tag shows correctly
    TZID:America/New_York
But later on I see the reference
    TZID=3DAmerica/New_York:20201216T100000

Am I missing something in the translation as to why all equals are 
followed with 3D? Is this what is causing the Calendar invites to be 
misinterpreted by Outlook clients?  How is this corrected?

Raw message (redacted) sent is below.
