Outlook Teams created on all calendar entries

Apparently this was being rolled out globally by Microsoft and it looks to have hit our Tenancy in the past few days.

This affected our O365 outlook as well as clients. Every meeting request made automatically turns it into a Teams meeting. We want to switch this off rather than it being forced upon us. The workaround at the moment is to click on the teams icon and click Do not host Online.

 

I've set OnlineMeetingsByDefaultEnabled $false against our Exchange online and this has switched it off for O365 but the clients are still applying it. We're running Outlook 2021 LTSC Build 2108.

 

There are many articles around pointing towards a check box in settings but this is only available in build 2208 and above. LTSC is not at that level.

 

Something has obviously changed in the client for it to start doing this and I can't see any online, GPO or registry setting to force this off. Has anyone else experienced this and know how to turn it off?
