We have set mapi over http :
internal Virtual directory : https://mailserver.domain.com/mapi
External Virtual directory : https://outlook.domain.com/mapi
Internal and extarnel authenthication : negotiate
When connecting from internal (lan) outlook 2013 will start and is sucsesfull connected.
When connecting from External outlook will ask for a password , once we fill in the password then it is connected sucsesfull.
But when a computer has joined the domain we want not to fill in a password.
What could be the trigger that i need to fill in the password?
