So in my current project I am working on deploying Office 365 in our Organisation. I had an issue in the early stages of testing where some users would get a pop up box (as below) asking for their credentials to activate the product.
While this was not a showstopper, we did not want this coming up for every user once we go live with the rollout to over 1300 staff members. There were a few factors which caused this to happen and the fixes below.
I was under the impression we were running Active Directory Federation Services. After speaking to one of the System Admins I found out we were actually running Seamless Single Sign On instead. To prevent this from coming up there were a couple of steps which I had to do.

- For Windows 10 systems it automatically supports AD SSO. For Windows 7 and 8.1 devices I had to install an extra piece of Software called Microsoft Workplace join for non Windows 10 computers here - https://www.microsoft.com/en-us/download/details.aspx?id=53554
- On top of this I also had to setup a Group Policy which would allow two Microsoft sites into the Site to Zone assignment list (as below). Note this also needs to combined with any other IE GPO which add sites into your trusted zone as they seem to conflict.
