I'm using Outlook 2007 SP2 with Exchange 2007 SP3 in Cached Mode and I cannot search the mailbox using the Instant Search feature. When I try to, Outlook says some items are not indexed (more than 40,000 files).
So far I've created a new Outlook profile and allowed my mailbox to cache from scratch. Under Indexing Options in Control Panel I've clicked the "Rebuild" option but it sits on 156 files indexed for ages and never increases.
If I logon to another PC in the office, it works fine and indexes the entire mailbox in about 15 minutes!
Can anyone help me resolve this issue please?
As you are using cached exchange mode, follow the below mentioned steps to use the Instant search feature.
Restart the system after the process get finished and Instant search will work fine. For more information you can check the following resource -
