I worked in a small company that worked closely with other similar, local companies. We all had independent IT. One day I got an email from one of the other IT teams asking me to reset their admin password as they'd lost it. I replied saying I couldn't as I didn't have access to their system. It took a bit of persuading that I couldn't help. They then asked how they could reset the admin password. I told them it probably wouldn't be a quick and painless process (just as it shouldn't be)
The admin password they'd lost was the global admin account for their Office 365 tenancy.
Biting the hand that feeds IT
