    Make sure these registry values exist in both SOFTWARE and SOFTWARE\WOW6432Node locations.

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SOFTWARE\IM Providers\MsTeams]

    "FriendlyName"="Microsoft Teams"

    "GUID"="{88435F68-FFC1-445F-8EDF-EF78B84BA1C7}"

    "ProcessName"="ms-teams.exe"

    [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\IM Providers\MsTeams]

    "FriendlyName"="Microsoft Teams"

    "GUID"="{88435F68-FFC1-445F-8EDF-EF78B84BA1C7}"

    "ProcessName"="ms-teams.exe"

    Still having this issue. The DefaultIMApp value keeps reverting from MsTeams to Teams and breaking the presence/chat function in Outlook. All stated resolutions only temporarily resolve the issue. Comes back within a few hours.

    Hi All,

    We just migrated our employees to MS Temas ( new version v2 ) and the OUTLOOK 365 status not showing.

    also, this option is not available at all (Register the new Teams as the chat app for Microsoft 365(requires restarting Microsoft 365 applications)), although, I am updating the Teams client regularly!

    Any idea?

    Thank you so much for this, It works!

    I have had the original issue with the checkbox not clicking in Teams and running as administrator fixed it,

    however, after restarting Teams and Outlook I still did not see the presence status in outlook.

    After updating the Reg keys you listed it worked after restarting the apps.

    Many thanks!!!!
