The further development of the interfaces provided by Microsoft for Teams is continuously monitored by estos.
- Predominantly read-only access possible
- Reading out of presence information only in the beta channel (https://docs.microsoft.com/de-de/graph/api/presence-get?view=graph-rest-beta&tabs=http)
- Set presence information only as a feature request (https://microsoftgraph.uservoice.com/forums/920506-microsoft-graph-feature-requests/suggestions/41024284-allow-updating-user-presence-via-post-presence)
- Skype for Business Function (https://docs.microsoft.com/en-us/microsoftteams/manage-external-access)
- Will in all likelihood be switched off together with Skype for Business on 31.07.2021 (Skype for Business Online to Be Retired in 2021 - Microsoft Tech Community)
Currently, from estos's point of view, there is no possibility for meaningful integration.
