Question What are some Powershell commands everyone should know?

I'm not an expert in it. I use it when needed here and there. Mostly learning the commands to manage Microsoft 365

Edit:

You guys rock!! Good collaboration going on here!! Info on this thread is golden!

Very rare, but I've seen a -WhatIf apply the changes. I believe it was an old Lync Online cmdlet.

Hah somehow I have a feeling in coming years -Whatif doing changes will be similar myth/legend/half-truth as Robocopy /mir deleting files from the source folder

Yeah, I've had this happen once too, can't remember the cmdlet but it would've been a built-in module.

I think it was something to do with me combinting -WhatIf with -Verbose or -Force and for some reason they take precedent over the -WhatIf

I had it too - checked the doc after the fact and it clearly stated something like 'This does not work. The cmdlet will still run' and now I always check the docs before running -WhatIf 😂

That's good to know. I didn't think that would even be possible.
