Outlook not syncing with 365. Connection Status Under Authn: Error
I can confirm we have been having this issue as well for a few weeks. All users on ClicktoRun version of office 365. It started after we enabled MFA on all of our user accounts recently, but even disabling MFA for a user will not fix the issue.
It's not all Windows 7 users, maybe 20%. One thing that does seem to be consistent is that all of the users having this issue have the "New UI" in Outlook (new icons).
Killing sdxhelper.exe and restarting outlook will temporarily fix the issue , or simply rebooting, but it always comes back. It's happening multiple times per day for some users.
We are having the same issue with Click to run Version 1810 (Build 11001.20108)
The sdxhelper.exe work around does work however it doesn't explain the cause. What specific Version and build are you running?
Same version (16.0.11001.20108) on one I just checked, but we've seen it happen on other builds as well.
I just updated a few clients to 1811 (Build 11029.20079) and patched for https://support.microsoft.com/en-us/help/3140245/update-to-enable-tls-1-1-and-tls-1-2-as-default-secure-protocols-in-wi
I'll post back any change in behavior.
I had the same problem from the past 2 weeks I think.
This morning I took a look at it with a finer comb and saw the SDXHelper being the culprit (ironic - its not helping anything :)) - before finding this thread.
Just also updated Office to 1811 - hopefully this will fix it.
