Zoom / Google Calendar integration

[frankwatson]

If I make an event in my Google Calendar and invite a Microsoft 365 user running outlook within seconds of the invite being created I get a decline message back that the user declined the meeting. The user hasn't even opened the invite - the user has no policy to auto decline/accept meetings and there is no trace of an email declining the meeting in the Microsoft 365 system (We did message trace and only see the invite coming IN).  DMARC and SPF etc are not the issue. The user receives the invite and can accept or decline (which then sends back to my gmail inbox) but I have already received multiple calendar responses for the invite.  I can turn the zoom chrome extension off and this doesnt happen. Anyone have this happen in the past with the zoom integration??

This sounds like a compatibility issue between Google calendar and Microsoft 365 which is leading to a mix up with the RSVP status. You could try creating the invite in Outlook directly if you are inviting Microsoft users. Another solution is a Zoom app, Salepager, that lets you send Zoom calendar invites that both Microsoft and Google calendar compatible.
