Are your Outlook clients in cached mode? Check the sync issues folder to see if anything is failing to synch like the OAB

Hello,

What all the third party applications have you installed on Server? Like ANti Virus....

Set the proper exclusions for anti virus..

Check the eventvwr for more help... Also Disbaling cache and enabling the cache mode again.
