Outlook 2010 / Exchange 2007 slow to connect

Hi,

I am dealing with an issue regarding outlook 2010 taking more than 1 minute to connect to an exchange server over a WAN.

Is there some behavioral differences on how outlook 2010 connects to an Exchange 2007 server? There are around 45 users at this site.  The lack of a domain controller configured as a global catalog server crossed my mind.

I have asked the user to try turning off exchange cached mode and back on again whilst i investigate other things that might be causing the issue.  Was thinking that there could be large OSTs even though the mailbox on the server is only around 100 mb.

I believe they are only having issues with outlook over the WAN.

I would also check to see if it is failing (or trying to fail) back to Outlook Anywhere.
Look at the Outlook connection status (hold down ctrl while right clicking on the Outlook icon in the system tray). That can give you some good information on the delay.

You should have a global catalog on the same site as the end users and in the same site as the Exchange server.

I have a suspicion that the clients machines are authenticating against domain controllers in a remote site, by-passing the domain controllers they should be authenticating against in a datacenter.  Thanks for your comments so far...

All subnets are part of a single AD site.  Unsure if this is a good configuration when you think in terms of hops..
