Office 365 passwords are set to expire every 90 days. The annoyance of this may outweigh the security benefit it brings for some (many?) users. But fear not – it is possible to get rid of the expiry altogether using Windows PowerShell with the Microsoft Online PowerShell module.

- At the PowerShell command prompt type:
Set-MsolUser -UserPrincipalName firstname.lastname@example.org -PasswordNeverExpires $True
