Especially as the announcement says "Sage is actively working on QuickCal 1.2"..... we would like the focus to be on the Exchange Integration patch more. 

Agreed. The "tone" of the announcement suggests that it will be a longer wait than expected.

We've just taken a decision this morning to go for it and build our own Graph API-based Exchange Online calendar sync for Sage CRM. We're going to include the Teams 'isOnlineMeeting" toggle within the communication and allow the storage of meeting transcription data. We've already done quite a bit of the core code for a custom field service management extension.  Not quite sure what the delay is... but my team are hoping to get a beta out as soon as the end of this week for one of our partners.

Hi sean, have you developped a working solution ?

Hi Stanislas_p ,

We have, but it turned into a larger integration project, spanning deeper into the Graph API for Teams phone with PSTN. A customer uses Teams as their core phone system and as part of the sync service we were tasked with developing telephone in/out recording.
