Office 365 and Google GSuite-Can They Coexist in a Weird Situation?

We're currently on a Google Workspace Enterprise backend with Microsoft Office 365 Desktop App licenses for most people. We have a few folks on E3 licenses and have a full Azure + MS 365 Tenant setup so accounts including email addresses sync for license management as well as syncing to other backend systems.

I recently enabled Teams on our Tenant for 1-2 users who need to login to Teams for external invites or send an external meeting invite instead of using Zoom.

I noticed that the only way to send a Teams invite is the "Meet Now" option as the calendar is disabled due to Exchange being disabled on our Azure tenant.

It appears that to generate an actual invite via Teams in Teams you need to use the Outlook calendar and that Exchange/Outlook needs to be enabled. Since MX records point to Google Workspace I'm wondering if I enabled Exchange in our Azure tenant so these 1-2 users could send proper Teams invites or at least copy and paste a calendar invite into their Google email if something would break such as email.

I'm pretty sure it won't but I wanted to see if anyone else has had a similar situation before?

If your using E3 licenses, users should have been created with an Exchange mailbox. the .onmicrosoft.com default domain for your tenant should have an MX record published by Microsoft. You -can-setup a co-existence model with subdomain email routing between the two environments. It is messy as (&@#($, but is possible. They key to the process is to not set the domain as being authoritative in the Exchange Admin Center. This way sent email is routed to your preferred servers instead of to the users Exchange mailbox.
