I am using ms teams 2.1 as a published seamless application with shellbridge enabled. I am using a Ivanti EM process started (ms-teams.exe) trigger to check for the existence of app_settings.json and if it exists i am then using an action to update the text in the json so the setting "keep_app_running_on_close" is set to false it works great apart from the first launch as the json file only gets created at 1st launch. Subsequent logons the keep_app_running_on_close is set to false and closes on exit as expected which is what i want. The first launch issue is causing me a problem as when you close ms teams it keeps running in background and even if you close all the remaining seamless apps to log off the session it is left active as the process ms-teams.exe is still running. Ending the ms-teams.exe process manually in task manager/director then logs the session off gracefully. I was thinking of adding the ms-teams.exe process into the logoffchecksysmodules reg key but was under the impression citrix dont recommended adding published seamless apps into the logoffchecksysmodules reg key???. Is any other way i can get round this 1st run issue ? speaking with other people copying in a pre formatted msteams 2.1 app_settings.json isnt gonna work
