Hello,
in an effort to switch to a shared licensing model, we are re-deploying Office 365 via ODT.
However, after re-deploying it, Outlook just will not connect to our on-prem Exchange server but instead connects to Exchange online.
The attached "ODT 365.zip" file contains the two files:
- configuration-Office.xml | This one was used initially, everything works fine and Outlook connects to the on-prem Exchange without issues. However, it's not shared licensing.
- configuration-Office365Shared.xml | Everything but Outlook not connecting to on-prem works fine as well.
We've already tried the registry fix mentioned here: https://techcommunity.microsoft.com/t5/office-365/outlook-365-outlook-install-does-not-see-local-exc...
>> HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\outlook\autodiscover
DWORD: ExcludeExplicitO365Endpoint
Value = 1
However, that registry key does not exist in our environment. There was mentioning of a different path in the registry somewhere (can't find the link anymore), but those paths did not exist in our registry either.
We also tried manually adding the on-prem server by manually setting up an account in Outlook. This did not work either.
So how do we manage to get Outlook 365 to connect to our on-prem Exchange server when installing it with the shared license option? We do not have a hybrid model yet and are not using Exchange online yet.
***EDIT***
I should have mentioned this is in a VMware Horizon Instant Clone environment.
Thanks!
