I have a new client that is running Exchange 2003 Standard. The store was increased, but the value of 70 was entered as hexadecimal not decimal. When I check the decimal value it is 112. The actual size of the store on disk is 25G. Can I correct the registry entry to 70 decimal without impacting the store? Thanks, Mike

If the size of the store is only 25G then you are still way under your new 70 limit. You can safely modify the value and then restart the services. Here is the web page talking more about the 2003 registry setting regarding store sizes. http://technet.microsoft.com/en-us/library/aa998066(EXCHG.65).aspx Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question.
