Recently I have added a new server to out domain, os is windows server 2008 r2 64bit
and exchange is 2010, I have an old exchange 2003 server that i moved it's mailboxes to the new one. I am having issues with a similar error also when clicking the address book or trying to make a new meeting it says "bookmark is not valid"
I also can't open an outlook account if I type the new server name and the username when i try to lookup it says "bookmark is invalid" could this be a dns problem? and if so where should I start checking?
