Outlook show add service prompt
We have exchange 2016 on-prem.
Suddenly some users are prompted with a “add a service” window, while using outlook, which ask for credential with a message that “ no work credential are found” and showing the “local” domain account credential as “email’
we cannot understand which service is referring to since we did not make any change to the organization
Any idea why is this happening ?
It happens only to some users not all.
Most of them have Office 2021 Home & Business ed.

Did you find a solution to this problem? We are experiencing it often with our on-prem exchange users and its prevents them from getting mail but it wants them to login to their office 365 account used for licensing the client, not our domain or exchange server. No idea why but it prevents a connection to exchange preventing new email from being received or sent from the client.
- AnthonyBurns455Copper ContributorBest to add the following key to the registry to disable the explicit o365 endpoint -
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\autodiscover]
"ExcludeExplicitO365Endpoint"=dword:00000001
"ExcludeHttpsRootDomain"=dword:00000001
- Dan_SnapeSteel ContributorMake sure both Exchange and Outlook have all the latest updates/patches installed. You can usually see what connection is causing the problem by checking the Outlook connection status https://learn.microsoft.com/en-us/outlook/troubleshoot/connectivity/description-of-the-connection-status-dialog-box
