Running Active Directory in 2003 mode (with 2x 2003 and 2x 2008 servers) and Exchange 2010 in DAG.

Ran through and installed the above executable, ran with my domain admin credentials, but I could not get the pictures to show up in Outlook no matter what I did.

Finally figured out it is an issue with the offline address book – rebuilt on the Exchange side and no dice. But deleted the cached folders on my local machine and it worked fine. There’s also a registry key to help out:

Close Outlook
Delete everything in C:\users\yourusername\appdata\microsoft\outlook\ofline address books\
Open Outlook
Profit

Registry key:
[HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Cached Mode]
“DownloadOAB”=dword:00000000
Either create the key “Cached Mode” and then the 32bit dword “DownloadOAB” as 0 or save the above as a .reg file and then run that.
