During the migration phase ,one user came to me and complaint that he cannot manually download offline address book in send/receive outlook . Then i realized that all the users who are on exch 2010 are having the same issue .User's still on exchange 2003 are not having any issue's
I have tested the autodicover via the Ctrl + right click the outlook icon then select test email AutoConfiguration... it came back with no errors.
I cannot see anything else is effected by this ....
Please help me in solving this.
