Outlook 2010 / Exchange 2013 cross domain
Posted on 2014-01-31
Current domain: SBS2008 with exchange 2007. Windows 7 clients member of domain using outlook 2010
We have configured a new domain (due to sbs limitations no trusts possible), based on server 2012 and exchange 2013.
We first want to move the mailboxes from 2007 to 2013. We configured the users and mailboxes on new domain.
We tried to connect as member of sbs domain to new 2013 exchange server, but errors like cannot connect/resolve and so on.
Found solution with registry:
Here add a key with ds server referring to GC
Now when creating profile, it finds the mailserver, it can find the mailbox and gives us username/password window. However, none of the credentials are working, 100% sure they are correct. Any tricks/tips ?
