I have been using Outlook 2007 in Vista and XP for some time now. There is a
bug that is still unresolved since Outlook 2003 (I believe) that causes LDAP
searches to take very long and hang up Outlook while doing so.
There is a registry hack that successfully
It has worked fine for us under all versions of Vista and XP. However I
recently upgraded to Windwos 7 Ultimate (32-bit) and it seems this workaround
no longer works. Anything that requires an LDAP lookup (such as CTRL+K in an
address field) will hang up Outlook for at least 30 seconds before it brings
up a search window or it finds the name, and then another 30 seconds or so
when moving between fields or sending the message.
For the record, the N2K file is fine and it actually
fine. It is when the name is not found in AutoComplete that this happens. If
I remove LDAP altogether and search only against the GAL or my personal
contacts, this does not happen.
Our LDAP servers are running either OpenLDAP or Sun Enterprise Directory
