Outlook 2010 and 2016 Password Sync plug-ins Office 365

As others have probably found as well Office 2010, 2013 and 2016 do not provide a true SSO experience when connect to Office 365 and prompt the user for a password unless you select remember password. We have over 10K users and this is going to be a big problem. Does anyone know of a third party plug-in that can sync a users local on and pass it through to Outlook and Office 365?

Office 2013 SP1 and Office 2016 do support true SSO via ADAL. For older versions, simply use credentials manager.

I would suppose you would need to use the supported versions of Office 365 ProPlus to realize the full capabilities of SSO. As of 28 Feb 2017, the only supported Office 365 ProPlus version will be the 2016 version. Additionally, of the "retail" versions, only Office 2013 and 2016 are supported with Office 365.

I have downloaded and install Office 2016 from the o365 port and it still prompts me for a PWD...

What do you mean by SSO by ADAL? Do you mean ADFS???

Have look at modern authentication but you cannot use active sync

ActiveSync has nothing to do with Office/Outlook on desktop. The Outlook app on iOS/Android should actually support modern auth, however you cannot get a seemless SSO experience on mobiles unless you preprovision them via Intune or similar.

I assume that you configured the desktops properly?

We really did not configure anything on the clients.. 1) Created a new profile 2) Autodiscovery configure the correct information 3) Confirmed that all servers settings were correct for the o365 setup as Per MS recommendations

I did run the tool you mentioned for the o365 test every came back green with one waraning...

From what I have read online the cert warning is not an issue but have read countless article online of other using Outlook 2010 - 2016 with o365 and getting prompted for passwords

Any further thoughts on this? I see numerous posting online about other seeing the same thing with Outlook prompting for users pwd after moving to o365.

It looks like SSO if not fully support in Outlook as of yet but getting close with Outlook 2016 and modern authentication
