I read in another post that if I delete all additional mailboxes in my Client that these folders would be faster. I have about 10 additional mailboxes in my Outlook. I tried removing all of them and it does work faster. Still slow, but manageable.

Does this happen with Outlook 2007 or Outlook 2003?

This is happening to us as well. I thought if I migrated the public folders to Exchange 2007 it would be faster and it is not. Still VERY slow to access public folders using Outlook 2010. Our DB is only 1 GB.

On the Exchange 2003 Server try the following.

Start Registry Editor.  
Locate and then click to select the following registry subkey:


Note:- Create the \ParametersSystem registry subkey if it does not exist.

Add the following registry data to the server:

Value type: REG_DWORD
Value name: Maximum Polling Frequency
Value data: 5000 (decimal value)

Exit Registry Editor.

Restart the Information Store Service for the Settings to take Effect.
Then check if the Public Folders is any better.
