Zoom Room with O365 Calendar Integration shows some meetings without links



We are using Zoom Rooms with O365 resource calendar integration. When we create our appointments by ourselves all works fine but when we forward external (teams) invitations to the room resource, the meeting event appears but does not have the link to open the teams meeting from the list of events. 


Here is the question:

Which are the technical requirements for a meeting link to appear correctly?


- Teams-link in location? Any special characters or keywords?

- Teams-link in description? Any special characters or keywords?

- Teams-link in attribute onlineMeetingUrl?

- Must the attribute isOnlineMeeting be true or not?


Please help with a detailed definition of how do you interprete the meeting links from the events...



What I have learned so far is that Outlook generates a proper onlineMeeting object in the self-created appointments


If this object is missing (because the invitation has been sent from outside or has been forwarded), the link in the Zoom Rooms meeting event list is missing.

A much more convenient way to solve this is to have a look at multiple fields of the event whether or not you can find a link like or and the display a button. 

What we have now fails in all externally created invitations.

Any recommendations?

After a long trial and error session I now have found the rule for "when does a zoom room show a join link or not when using calendar integration with O365":

Describe the bug:


If this is the body of a teams meeting invite (url as the link display text):


Online meeting: <a href=\"<meetingId>\"><meetingId></a>


it does not lead to displaying a "join" button on the Zoom Room event list with calendar integration.

Whenever I changed the link like this (plain display text):


Online meeting: <a href=\"<meetingId>\">Join Meeting</a>


the join button appeared on the Zoom Room.

I urgently request Zoom to change this so that however the link is pasted into the meeting body, Zoom understands it right. Do they listen here? Then please tell me what you need in addition to improve this in a next release...



Dont mix up 2 different scenarios:

a) External people directly inviting your room .
this is by default not possible but can be enabled on the Exchange side with this:
Set-CalendarProcessing -Identity -ProcessExternalMeetingMessages $True 


b) This can be tricky indeed.
Lots to learn about it here:
Hope it helps
