Having a strange issue with Outlook Web Access on Exchange 2010 SP1.
A user reported that he was no longer able to search his contacts through the OWA interface. (GAL Searches work fine, it's just personal contact searches). He can view all his contacts still, and scroll through them, but searching won't work.
Initially I couldn't reproduce the issue with my account, but then I noticed it has to do with the amount of contacts the user has. Personally I have a very limited number of contacts (<20) and my searching works fine. I logged in as a different user that has a large number of contacts (couple hundred) and searching fails completely. It is not user-specific, I have tried with a few different users that have a large number of contacts and it is the same results.
There are definitely contacts matching the search criteria, yet it returns No Results. I have tried searching for a contact that appears first in the list and ones that are further down the list. This happens when searching from "Contacts" and from clicking on the "To:" button when composing an email.
Anyone have any idea on what could be causing this or where to start troubleshooting from?
