Outlook with local exchange account asking for Microsoft online login

au flag

I seem to have more and more issues with Microsoft pushing to try and force everything into their online service lately.

As of today I suddenly have two workstations that refuse to stay connected to Exchange. This is a local domain and a local Exchange server. Out of the blue they now pop up with a Microsoft online login window on start-up. If I close the window, the account status changes from being happily connected to Exchange to "Needs Password".

The login box is pre-populated with username@ad.mycompany.net, and trying to click next just errors that "This account isn't on our system" (yeah, big surprise, it's a local domain, local exchange and nothing to do with Microsoft online).

What am I supposed to do about this? What is the correct way these days to let my users connect to their local exchange account without Outlook demanding they log into a non-existent Microsoft online account?

You could follow the steps to create ExcludeExplicitO365Endpoint registry value to bypass connection to O365.

1.Press win+r, then type regedit on the outlook client.

Find the below path. (If you do not have the AutoDiscover key, please create it under the HKEY_CURRENT_USER\Software \Microsoft\Office\16.0\Outlook.)

HKEY_CURRENT_USER\Software \Microsoft\Office\16.0\Outlook\AutoDiscover

2.Create a new DWORD parameter named ExcludeExplicitO365Endpoint and value 1 , then restart Outlook. enter image description here 3. Check if the issue persists.

Thankyou. Was driving me mad having users suddenly not work but struggled to find anything relevant online.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
