My customer has a small office with 8 users using SBS 2008 / Office 2010. They have been reporting performance issues and typically a message is shown stating that Outlook is retrieving data from Exchange Server and sometimes Outlook shows as Not Responding for periods of time before resuming normal operation. I posted this problem previously and was advised to increase the memory in the server which I have now done taking it to 8 GB. There is some improvement but the users are still reporting delays.
The users all insist on sharing All of each other's folders including deleted, sent items, calendars etc. Outlook is set up so that all the other users mailboxes are opened when Outlook is started. They are also disinclined to archive anything so on average the folders contain 2000 - 8000 mail items. With caching set to On, the offline folders become very large ( e.g. 16 GB) and I think that this is maybe contributing to the problem. I would like some advice on how would be best to set up the caching and whether having all the folders in all the mailboxes open for each user is a good idea. Also any further suggestions on how I could improve performance .
Other possible relevant information.
I am using the Redemption Add In to allow mail to be sent from a custom Access DB.
I have applied the latest Office Service Packs .
