Hi I'm using Thunderbird 102.13 with "Owl for Exchange" add-on , on a Ubuntu 20.04 LTS laptop I also have the MsTeam App installed on the same machine Since a few weeks/months, I have seen in the left vertical toolbar of Thunderbird, appearing the icon of MsTeams Don't know if it's due to the Owl add-on or if it's native to Thunderbird The other day, I finally give it a try ... and I like it It open the App (from the installed version??) in one tab of Thunderbird, avoiding to open another application Everything works fine, except a little annoying problem which almost ruin the experience : I have no notification when someone try to contact me in the chat ! The notification works with (external) the App (a little bit too much ! ) Is there a way to have a notification coming from MsTeams embedded in Thunderbird ? Thanks in advance for your help Best regards
