I took the plunge today and did a clean install of Windows 10 pro downloaded from MSDN. pleased to say it was the best install experience of any OS i've worked with. the performance is also incredible, everything is very snappy & responsive.
during setup, i opted for "my organisation owns this computer" and i signed in with my Office365 (E3) login details, i also opted to apply the default security policies. the office365 account had only been used to sign in to outlook online, and was never used for Azure active directory / windows login. the setup completed and i can log in directly to the desktop no problem. i noticed however that i could not sign in to one drive, i kept getting prompted for the username and password, and it was rejected every time despite being correct. i have no trouble accessing one drive via the web interface. also, now i noticed that i am unable to access this PC when logging in remotely via remote desktop (from a Win 8.1 PC). the credentials are correct.
it's a mystery. i have a microsoft ID (personal email address - no outlook/hotmail/live email etc) that i've had for years and this is linked with a Microsoft Action Pack subscription. i needed to sign in with these credentials on the Visual Studio license activation screen. i now notice that when i sign in to Office365 via web browser, i am prompted with this question (new since installing windows 10):
Sign in with your work or school account
It looks like XYZ@MyCompany.com
is used with more than one account. Which account do you want to use?
Work or school account (Assigned by your work or school)
Microsoft account (Personal account)
having searched around a lot today, i came across this thread which explains how users are forced to have separate Microsoft accounts - even with the same username/email - to span services like Office365 and MSDN / Action Pack. this seems to describe my situation well, but i can't find any solution to the onedrive & remote login issues. can anyone suggest anything i can try? Many thanks.
