One thin i have noted , although not consistently, is that cached mode sometimes "breaks" the search function on outlook 2010 with EX 2010- AGAIN not consistently,

Those particular mailboxes are configured in non-cached mode, even if part of a profile that includes cached access to the user's own, non-shared mailbox.

The main issue with PST files was their tendency to corrupt when they got past 2gb but that was addressed with the Unicode PST format introduced with Outlook 2003. They are still an issue for other reasons (not supported on file shares and thus vulnerable to loss, very hard to discover/control,etc). OST files on the other hand are much less of an issue as it’s just an offline cache of the Exchange mailbox. They should live on a local drive to the user workstation (do NOT put them on a mapped drive) but are otherwise pretty forgetablle with Outlook 2003+. They occasionally get corrupt (usual symptom is Outlook stops updating) but you can just delete the file and let Outlook rebuild it. Using cached mode will take a significant burden off your Exchange servers.
