I have been working for 3 weeks on an exchange 2010 rebuild from a server crash with little to no data backup. I have completed a number of steps to get this backup up and running and have completed the users data re-population from OST converted to PSTs. Fortunately my AD server was another system so i have been able to copy some configuration from it but I now have 1 issue I have not been able to resolve regarding the default GAL
Basically in cache mode on outlook 2007 and 2010 clients they see a copy of the old Gal (I believe) as it has a number of users that I did not add to the new rebuilt server (called the server a new name exchserver3) but only in certain areas for example new email shows the list but add-delegates does not
If I turn cache mode off I see a GAL in delegates but is still shows all these old users but with a red circle/line through their icons.
I tried to use the send/receive - download address book and full details but in the pull down option in the bottom the \Global Address Book option is not there
I do have a somewhat retired exchange 2003 server on the domain still (and I used it to create and move user mailboxes to as part of the recovery) so perhaps this has something to do with the strange behavior.
Also, I created a new global address list call "test GAL" and I can see it on the exchange but not on the client or in OWA. (used EMS command to create it)
please let me know your thoughts or if you need any further information
