Empty body description received by attendees Outlook 360

[jgato]

Your environment

TbSync version: 2.16.2 EAS-4-TbSync version: 1.18 Thunderbird version: 78.2

[X] Yes, I have installed the latest available beta version from https://tbsync.jobisoft.de and my issue is not yet fixed, I can still reproduce it.

Expected behavior

When I send an invitation to an attendance list with a description. They receive the invitation and can read the description.

Actual behavior

I create an event, with attendee list and an event description. Attendees receive the event, time is oka, but there is no description. If you open the .ics file the description is in correctly there, under the tag: DESCRIPTION.

But their client (different clients, outlook web, mac os..) is not filling the description

And this is the .ics attached:
