How does Microsoft Online Services Sign in Assistant Works?

Hi Mark,

Here is a wiki introduces the Microsoft Online Services Sign-In Assistant (MOS SIA), for your reference:
https://community.office365.com/en-us/w/sso/534

Regarding your situation, would you provide us with some more detailed information about “When I logged in My and open the one drive site it asks me password”, do you encounter this in the desktop OneDrive client or Office 365 portal from browser? Could you also provide a screenshot about this for our reference?

Hi Allan,

I don't get how MOSIA works, i've installed it in my PC. Office 365 Portal - this is single sigin right ? when I logged in with my pc using my domain e.g company\mark i don't have to sign in my outlook client because MOSIA is installed is this correct ? and when i open onedrive Office 365 portal also it should not ask password right because MOSIA is installed ? can you clarify more.

Regards,

Mark

Hi Mark,

MOS SIA doesn't mean Single Sign-on, it only works for some special Office application such as Azure Active Directory Module for Windows PowerShell/Lync to authenticate to Microsoft Online Services. So you still need to enter your password to Outlook or Office 365 Portal.
