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 troubleshoot 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\*\AppData\Roaming\Microsoft\Teams\*" -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.
