Problems Defragging/Compressing Exchange 2000 Mailbox Store
Posted on 2008-10-04
I am having a problem compressing my Exchange 2000 mailbox store.
My Exchange server has reached its 16GB limit. I have enabled the temporary 17GB store size limit to allow the users to log in and move older mail messages to archived PST files or delete them all together. When I use the Exchange System Manager for the size of the mailboxes, now the total size of all mailboxes is down to about 8GB.
I have run the Eseutil /d command to defrag/compress my mailbox. Unfortunately, this did not have the desired result. The combined size of my priv1.stm and priv1.edb files are still about 16GB combined. I have run this three times now, once using the /t temporary flag hoping this would create a new file all together. All attempts have had the same result (ending files are about 16GB combined). I have also run the isinteg command, but this did not seem to have any effect.
Researching this issue, I have examined the white space of my mailbox store using eseutil /ms. If I am reading this correctly, the number listed as "Free:" at the end of the first section is to be multiplied by 4096bytes to determine how much space can be recovered in the STM file by a defrag/compress process. This number is 97. Does this mean that I will gain only 400KB?? The number at the end of the test is 5793, which by my understanding is the amount (* 4096bytes) that can be recovered from the edb file (roughly 23MB??).
My question is this: If Exchange System Manager shows all of the mailboxes in my mailstore have a combined total size of about 8GB, and my STM and EDB files are 16GB, why does Eseutil /ms only say I can recover 23MB? Is there another way to compress this file? The next plan of attack I can think of is to remove all users' mail to temporary PST files and create brand new mailstore (a step I would like to avoid if possible).
Please let me know what I am missing.
Thanks for your help.
