We are unable to connect right now Outlook / Office 365 Apps

Hi all,

I'm getting increasing reports from users running Windows 10 build 1909 & 2004 that they are getting an error message come up when they start up and log into their computers when trying to run Microsoft Outlook.

On checking (the 2004 builds) I can confirm that Windows is reporting "no internet connection" with the glob icon replacing the network icon which seems to be the cause.

before we start and just to head off the usual answers that are all over the internet on this subject....
I've checked the registry on the offending computers and I can confirm the entry EnableActiveProbing is set to 1 as it is on my computer and yet I don't have any problems with my Office 365 apps.

The latest was a user yesterday. I "fixed" it by setting her network card to use a static IPv4 address as opposed to a DHCP allocated address. Reverting it back to DHCP caused the problem to reappear.

I'm now getting reports from other users using the 1909 build that they are getting the same error message but clearing it seems to fix the problem. All have EnableActiveProbing set to 1.

I'd be really keen to get to the bottom of why this is happening all of a sudden, was it a recent security update that I need to roll back ?

Kind regards,

    Hi, sorry for the delay... other apps don't need to contact microsoft to check for activation so no, it is only the office apps that are affected and in particular Outlook, though clearly this isn't an outlook issue.

    The troubleshooting methods are all fine and one or other of them will resolve the issue for that particular moment, but the next day the issue will return.

    I am considering wiping the machine and reinstalling Windows to a lower version just so we can get some stability back.
