Anyone running Teams 2.x in a seamless app in S19+? Based on what I'm reading, it looks like you're limited to basically running Teams PWA/Edge with no optimization. We have Teams installed in our desktop image, but you can't publish that shortcut as a seamless app.

you try this?

Why no, no I have not. My biggest question right now is how this even works for a new user who has no profile and has never launched Teams. Gonna try this now.

it's part of the msix provisioning process at logon

Ah, so this is from an App Package in DaaS? Where you create the source share, then add the Teams MSIX?

i blieve you can provision teams that way as well, but i'm just install teams machine wide natively on an image, and then using the screenshot values for app path/command line args. It's possible it acts differently with server 2025, but i didn't think so

Yeah, seems to. Not launching at all for me in an image where Teams is already installed.

and if you launch a desktop on that server you see it in the start menu and can launch it ok? You followed this for the specific server 2019 stuff? https://learn.microsoft.com/en-us/microsoftteams/teams-client-vdi-requirements-deploy

Yeah, everything works as expected on S25 desktop. I actually got it to launch using shell:AppsFolder\MSTeams_8wekyb3d8bbwe!MSTeams as the application, but threw a weird Citrix error before getting there.

so they were uploading the app package and publishing that way?

2402 CU2 in that S19 image. Not sure if it's even working, they were still testing.

just not 100% if the app package import through studio works on 2019, maybe others can chime in...i'd follow the specific server 2019 teams install procedure from the microsoft website though, especially if that app package method isn't working

Yeah, we've got Teams installed in S19 just fine, but we've been using it for desktop users. Trying to see if we can use the App Packages method for published apps.

I use ms team v2 as a seamless app with no issues I use uwalauncher. I use ivanti to edit the JSON file to close on exit

JSON... giving me flashbacks of Classic Teams

Can you prestage that entire file like you could in Classic Teams?

nah you cant copy it in 😞 hence why i had to do it this method

ugh. So we'd have to use WEM to run an external task to do this

thats my teams published app command line

Yep, that's what I'm using now

The other method i tested was this way but you have to grant users perms to that directory. I found the UWAlauncher method easier

Definitely. For the JSON modification, I assume this only takes effect on the 2nd+ logon? I modified the JSON and saved it, and it still closes to tray.

yeah only kicks in on 2nd logon let me check my logoffchecksysmodules

@c4rm0: Sorry for the barrage of questions, but what are you roaming for this? Same stuff you'd roam for Teams for desktop users? That is my assumption.

i exclude these <Exclude Copy="0">AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\Logs</Exclude> <Exclude Copy="0">AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\PerfLogs</Exclude> <Exclude Copy="0">AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\PerfLog</Exclude> <Exclude Copy="0">AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\EBWebView\WV2Profile_tfw\WebStorage</Exclude> <Exclude Copy="0">AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\EBWebView\WV2Profile_tfw\GPUCache</Exclude> <Exclude Copy="0">AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\EBWebView\WV2Profile_tfw\Service Worker\CacheStorage</Exclude> <Exclude Copy="0">AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\EBWebView\WV2Profile_tfw\Code Cache</Exclude> <Exclude Copy="0">AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\EBWebView\WV2Profile_tfw\IndexedDB</Exclude> <Exclude Copy="0">AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\EBWebView\WV2Profile_tfw\Cache</Exclude> <Exclude Copy="0">AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams\EBWebView\WV2Profile_tfw\Shared Dictionary</Exclude> <Exclude Copy="0">AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\AC\TokenBroker</Exclude>

Okay, those look like the same as ours. Something is definitely up with our session not dropping when you close Teams, though.

yeah i think that is why i had to use the keep_app_running_on_close and set to false as it was leaving the ms-teams.exe running in the session and it wouldnt log off

I used the system tray icon to exit Teams which worked, but the session stayed open. Weird.

i use the seamless flags reg value to block system tray icons so dont get the teams icon so couldnt even close it that way

wait, seamless flag reg value?

image.png

I haven't seen that key in years, lol

hmmmm, i might steal that seamless flag for onedrive status icon...thats set on the endpoint or vda?

It

on the VDA i set it via GPP. I have deleted it as a test on a VDA and logged off/on and you then get all the server side tray icons, gpupdate /force key gets put back and logged off/on and then no tray icons

It's a battle between doing what's right and doing what leadership wants

let's give them what they want, but hope they want what they get 🙂

the only thing that annoys me with it is the outlook icon (cant do test autodiscover ect)

lol

check director or task manager for open processes

i checked my logoffchecksysmodules i dont have any specific for ms teams

I did...e verything was open except teams, lmao

yeah, most likely something else in run reg keys

image.png

i miss ivanti

What is that key for?

controlling auto start of teams on logon

ah fuck

auto launch of teams on logon the other crap is i had legacy teams crap in the profiles (i had to migrate from 2016 to 2022 image as ms teams v2 didnt work on 2016 and retained same fslogix profiles so had to clean all the old legacy teams crap

So setting that to 1 prevents autostart

yeah

Awesome. I appreciate all of this, BTW.

I have read that page so many times that I forget half of its contents at this point

dont forget Location: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Teams Name: disableAutoUpdate Type: DWORD Value: 1

Yep, that's in my install script.

XenDpriv.exe,acrotray.exe,ISXAgent.exe,ISXAgent64.exe,sftdcc.exe,splwow64.exe,sfttray.exe,AppVShNotify.exe,AppVShNotify_orignal.exe,AppVStreamingUX.exe,AppVStreamingUX_orignal.exe,cognosrcp.exe,GPSViewer.exe,ccSvcHst.exe,RBRWSC.exe,ISXAgentBridge.exe,StatusTray.exe,analyticssrv.exe,concentr.exe,receiver.exe,selfserviceplugin.exe,msedgewebview2.exe,ISXSendKeysProc.exe,CtxMTHost.exe,AdobeCollabSync.exe,wfshell.exe

Looking at ours now and I wonder if I'm the first to look at this in years. Seeing apps that were removed 3 years ago, lol

FYI if you need to update the new ms teams in the image i just remove the teams meeting add in from appwiz.cpl then run teamsbootstrapper.exe -x / check its uninstalled via get-appxpackage -name teams / teamsbootstrapper.exe -p -o pathtomsixfile to install latest version / Then run a Teams meeting add on powershell script to install latest teams meeting add in.

We use App Layering, so that part is actually easy.

slimore optimization is now working for seamless ms teams app as well got it working

That was a backend config for you, right?

i did believe it was a ms teams tenant powershell setting on the tenant`New-CsTeamsVdiPolicy -VDI2Optimization` but it started working without that so must of already been set. I think i needed to reboot the VDA after the virtual channel allow all policy and client after installing the teams vdi plugin

I'm going to be using WEM to handle the JSON config and startup task stuff. Hope it runs quick enough to actually take effect, though. Could always go user GPP if need be.

fyi @c4rm0 you can use the --installTMA param now for the teams meeitng addin, and i usually leave out the -o, so the bootstrapper just downloads/installs the latest. I do have a some PS code that download and installs a new bootstrapper.exe every time

SeamlessFlags set to 0x20(32), edgewebview2.exe and ms-teams.exe added to LogoffSysCheckModules, and my custom WEM script to modify Teams close (which BTW is effective that very same launch)... but the session still does not logoff. The connection is active with no actual apps listed in Connection Center.

Check both hklm and hkcu run keys and confirm its not a process listed there. Also I dont think you need ms-teams.exe in the logoffsyscheck that might make it act goofy

this key in newer VDA versions shows you what process is blocking the logoff HKCU\Software\CitrixVolatile\Seamless\Sessions\[ID]\LogoffCheckerBlockingProcess

That key only shows ms-teams.exe

Haha I went through so much pain when I had to get it all set up

Well, you saved me a significant amount of leg work helping out a friend, so I appreciate it

So what was the process in the end?

A180RS.exe, Aternity

Security/monitoring stuff. Quelle surprise

Yeah, I was actually going to add it anyway just to test before I saw that registry value. Chuckled when I saw it in there.

I'd go further than punching

ya'll get a room! 🙂

Like one of those new rage rooms where they give you bats and stuff and you can smash things?

yes, that'll work lol
