PowerShell Basics: How to Delete Microsoft Teams Cache for All Users

Sometimes there is a need to delete Microsoft Teams cache to quicken the adoption of an in-band policy change or simply an issue. The challenge here is that the cache for Microsoft Teams is in multiple directories. This can be done manually but would result in a slow and tedious process. Again, we turn to PowerShell to automate this process and this time it's a one-liner that addresses this opportunity. 

Get-ChildItem "C:Users*AppDataRoamingMicrosoftTeams*" -directory | Where name -in ('application cache','blob storage','databases','GPUcache','IndexedDB','Local Storage','tmp') | ForEach{Remove-Item $_.FullName -Recurse -Force -WhatIf}

The end of the one-liner calls a -WhatIf which can be removed to enforce deletion.

As always, please share your comments below on bettering the above script or any questions you may have.
