Outlook 2007 Missing Names on Global Address List

S

Scott Christopher

Software: Outlook 2007 SP1
Exchange: Microsoft Exchange 2007
Active Directory Exists in: Microsoft Exchange 2003

Here's a bit of background. A few years ago our company split and
became two separate entities. We had to separate email into two
different domains, magnecraft.com and struthers-dunn.com. The server
was running Windows Server 2003 and Microsoft Exchange 2003. Late
last year, the struthers-dunn.com management decided that they wanted
to upgrade their e-mail hardware and software. A new server running
Windows Server 2003 and Microsoft Exchange 2007 was purchased. Almost
everyone that was located at the same location as the server was
accessing their e-mail using Outlook 2000 or Outlook 2003. They were
also connected directly to Exchange 2007. These are all of the
struthers-dunn.com e-mail recipients.

The way things are set up, the active directory remained in Exchange
2003, but the struthers-dunn.com mailboxes reside in Exchange 2007.

Anyone that is using Outlook 2000 or 2003, when they open the Global
Address List, can see all names for both domains

The issue is we are getting more users that are moving to Outlook
2007, and when they veiw the Global Address List, they cannot see
everyone. In fact, they can't even see all the names that are only
associated with struthers-dunn.com.

What I have tried:

1. I have rebuilt the offline address list in the Exchange 2003 and
Exchange 2007 software.

2. I have turnded off cache mode on the Outlook 2007 users. This
does allow all names to be seen. However, this creates another
issue. The junk e-mail filtering does not work. Left that way, the
inbox gets overloaded with junk that doesn't need to be there. I did
a test, with cache mode off, in a 24 hour period, there was about 48
items delivered to my inbox that would have be sent to the junk e-mail
folder. With the cache mode on, there was only 3 that i considered to
be junk, and there was 39 in the junk e-mail folder.

I don't know if the issue is with Outlook 2007 or either of the
Exchanges.

I would be very greatful for any help that anyone can give me.

Thanks.
