MS Teams App and user AppData folder

[mdrabble]

We have rolled out Office 365 Apps to our staff desktops including the MS Teams App.

 

I use a redirected AppData folder to the users home drive.

 

Noticed a sudden increase in the amount of storage being used on staff home drives and discovered that Teams is using an insane amount of storage in the AppData folder.

 

AppData\Microsoft\Teams\Service Worker\CacheStorage

 

Anyone come across this??

Does Storage Sense not handle clearing this data out?

[mdrabble]

Nope! Users cache storage folders were getting near the 1gb mark - that * 80+ staff and it zooms adds up - not to mention increased traffic erc

Weird. I have it running daily on all my machines and it seems to be doing a decent job of handling Teams and OneDrive caches. OneNote used to be my biggest pain, but I've had a logout script just deleting all of that for a while now... I might not even need it anymore, but don't fix what aint broke...

Did you get anywhere with this? Although I have tolerated it for some time, it's getting very frustrating now as the cache indefinitely sits in their network drive and doesn't budge or decrease! It wouldn't be too bad even if it cached to their local user profile as they're all using the same laptop (not roaming around).

I ended up redirecting the AppData folder back to the local drive as it was getting silly with logon times and also the amount of storage it was taking up.

We stopped redirecting it to and then excluded the directories from roaming profiles to stop the bloat. We also had a startup script to clear the cache folders on c:\Users\*\Appdata\Teams etc of all the cache folders as they where filling with bloat from Teams. Not had any adverse effects yet!

Must admit didn’t even cross my mind to use a start up script to clear the teams cache.

 

May have a look at that when I come to roll out 20H2

Necro!

@buzzard, did you have any negative effects from clearing the various cache folders? If not, can you share the script? Our 128GB SSDs are taking a hammering now from all staff profiles being 1GB+ thanks to these chuffing things.

 

I wouldn't mind so much if the one supposed benefit of Teams installing into profiles--that it's easier to update the client--actually bore out, but we have just as many problems with some users' profiles getting stuck on months-old versions that no longer connect to meetings properly...

Thread bump but we're getting insanely huge AppData\Roaming\Microsoft\Teams\Service Worker\CacheStorage\ folders - some almost 3Gb.

 

Did the script it was talked about sharing do the trick?

Hi,

I have used this on shared PCs. Have it run at boot:

Get-ChildItem "C:\Users\*\AppData\Roaming\Microsoft\Teams\*" -directory | Where name -in ('application cache','blob_storage','databases','GPUcache','IndexedDB','Local Storage','tmp', 'previous', 'Service Worker') | ForEach{write-host Removing $_.Name; Remove-Item $_.FullName -Recurse -Force}    
Get-ChildItem "C:\Users\*\AppData\Local\Microsoft\Teams\*" -directory | Where name -in ('previous') | ForEach{write-host Removing $_.Name; Remove-Item $_.FullName -Recurse -Force}
