Hello, My server OS is windows 2003 server and I am using Microsoft exchange server. I am getting an event error: Source: MSExchangeIS Category: general Event ID: 9667 Description: Failed to create a new named property for database "First Storage Group\Mailbox Store (Server1)" because the number of named properties reached the quota limit (8192). Question 1: How does one determine the cause for the named properties to reach the quota limit? Question 2: How to resolve this issue? Question 3: How to prevent it from happening again? Thank you very much, CaliKevin
