Hello, I am having to restart the information store service every couple of days because we are unable to access exchange email. We are a small company and have a very small exchange setup. ******************************************* Here is one of the error messages in the event viewer: Event Type: Error Event Source: MSExchangeIS Mailbox Store Event Category: General Event ID: 9690 Date: 8/10/2011 Time: 5:00:13 AM User: N/A Computer: SERVER Description: Exchange store 'First Storage Group\Mailbox Store (W2K3SRVR)': The logical size of this database (the logical size equals the physical size of the .edb file and the .stm file minus the logical free space in each) is 18 GB.
