I am working with SharePoint 2013 on-premise and I am running into an issue with the 'Sync to Outlook' task button.
When I try syncing the tasks to Outlook, the ULS logs read "
401 Unauthorized ....reason="
The tenant for realm 'my.domain.com does not exist.....";
I have determined that my issue is the SharePoint 2013 server is in one Forest and the Exchange 2013 server is in another. There is a discrepancy with the domain resolution, as SharePoint is requesting
firstname.lastname@example.org but Exchange expects
Is there a way I could setup a mapping for the Exchange security token (from SharePoint, or vice versa) that would translate the domain or realm that the user account should be resolved to in such a case? The base username is the same, but the domain is different.
