LoopMeeting is an Android application bundled with different Android based touch screen configurations. LoopMeeting communicates directly with MS365 tenant with MSgraph or EWS API’s using HTTPS interface protocol with TLS 1.2 or higher Encryption.
In order to restrict the LoopMeeting application to just a selection of your Exchange Online (MS365) resources you can optionally introduce an access policy as described below.
After applying an access policy, the LoopMeeting Application will only be able to access the resources/mailboxes that are specified in the Mail Enabled Security group. If you are not familiar with the implications access policy might have on your LoopMeeting installation, please consider if this is needed in your environment.
Note: Changes to application access policies may take more than 8 hours to take effect in Microsoft Graph API, even when
Test-ApplicationAccessPolicy shows correct results.
