I have what may be a fairly unique question. We have a large Remote Desktop farm using Outlook 2007/Windows Server 2003 and will be upgrading by replacing with servers on Outlook 2010/Windows Server 2008 R2. Users are external customers some with POP3 accounts and network attached PST files and some connecting to Exchange servers. My plan was to get the autocomplete email addresses to migrate was to copy their .NK2 files from their 2003 roaming profiles into the newly created 2008 R2 roaming profiles and have Outlook "autodiscover" the files and throw them into the new "autocomplete.dat". This works great for our customers with POP3 accounts. However it seems like half of the Exchange customers get extra entries that appear to be duplicated. It's now my understanding that Exchange will hold autocomplete settings so I'm just causing problems by bringing over the .NK2 files for these customers.

My question is: Is there an easy way (ie registry key) that will help me determine if an account is connecting to an Exchange server so that I can bypass bringing over the users' .NK2 files?

You can search the profile keys for "/ou"

See what this key has in it

windows messaging subsystem\Profiles\profile-name\0a0d020000000000c000000000000046\

DWORD: 11020434

I have my exchange server listed in it - if it doesn't exist for pop accounts, then you can check for it. But you need to get the profile name unless everyone uses the same profile name.

There are other keys you can check - but the ~046 key exists in all profiles, so its easy to find.
