I have been a very happy Office 365 user since day 1, but yesterday suddenly my e-mail stopped working. And it was only when I tried to log on using OWA that I discovered that my password expired and that I needed to enter a new one. It seems that by default your password expires after 90 days.
As I do not want to reconfigure all the devices that use my 365 account every 90 days, I decided to disable password expiration. The only way to do this is via a PowerShell command, explained in every detail in this blog post.
Security is a good thing, but it would have been nice to get a little reminder e-mail that your password is about to expire. I am on the P1 plan, which is the “dummy” plan for individuals and small businesses; if I need to change a setting, I want to do this via the portal, not via PowerShell.
