Here’s a post to help you find the Service Request Wizard for Office365. I wasn’t able to find it when I needed it.
I was on the beta for Office 365 and I couldn’t remember my password. I had only 1 account. And then I found the chicken/egg scenario where I had to contact an administrator (me) to reset my password. Otherwise I could contact support via some hyperlink. There was a link to open a service request but that only gave me phone numbers … sorry but I’ve had very bad experiences with consumer support via the phone. I could not find a service request contact form.
Via Twitter, Paul Iddon told me of the Service Request Wizard. That gives me exactly what I would have needed – I managed to guess my password so I no longer needed help. But thanks to Paul anyway!
