I would like to share my experience with redirected to OneDrive PowerShell folder. Original path of the folder: C:\Users\<username>\Documents\WindowsPowerShell Redirected to OneDrive path: C:\Users\<username>\OneDrive\Documents\WindowsPowerShell
Since folder was redirected, I get issues with uninstall of previous versions of the Az PowerShell modules.
Cmdlet Uninstall-Module with option -Force return successful result of the module delete operation, while modules folders remains in C:\Users\<username>\OneDrive\Documents\WindowsPowerShell\Modules folder.
I set option "Always keep on device" for WindowsPowerShell folder, retry delete operation, same result.
As workaround I use following solution - delete all Az modules folders from Modules folder. Since then I was able to uninstall old versions of the Az PowerShell modules in C:\Program Files\WindowsPowerShell\Modules folder.
PowerShell work paths remains without changes. Would be great to have option in OneDrive sync settings to exclude Documents\WindowsPowerShell\ folder from redirection to OneDrive.
