I am trying to configure Migrator for Notes to Exchange for the first time to migrate Domino to Exchange on premise.
I created a user in my exchange 2019 to act as an admin for the migraiton.
i give him the receive-as permissions on the database.
outlook 2013 pro plus and latests patchs applied, it is connecting well to his mailbox.
but when i configure the Exchange part on MNE, i got an error:
unable to open target mail store
and in console logs:
Microsoft.Identity.Client.MsalClientException: User realm discovery failed
System.Net.WebException: The remote server returned an error: (401) Unauthorized.
login for y admin user and password are correct as they works in outlook and even in owa.
So where can i check for more error report or do i need to change something in configuration ?
