PowerShell: Run Cmdlet If Another Was Successful (And Keep Trying Until It Is)

Fri, 23 Oct 2020 17:30:52 +0000

Today I’m sharing a useful bit of PowerShell I gracelessly punt from script to script whenever I need to make sure a prerequisite it met before running something and to keep checking until it’s met, then run what I need: “do X when Y is ready and keep checking Y until it’s ready”.

The original use for this was my script to create a new Microsoft 365 user, but hold off on some parts of it - such as time zone settings - until the Exchange Online mailbox is provisioned. That takes some time, so I wanted to keep checking and as soon as I could, continue the script.
