Exchange EseUtil /D Defragment Temp File Location

In the process of working on this Exchange 2007 database recovery we ran the eseutil /d defragment on one of the recovered databases.

The notes for the utility state that it should create the temp database in the same location as the database being worked on. Exchange and its databases were installed on a dedicated E:\ partition.

In this case it did not and we needed to run the following option:

  • eseutil /d “E:\Exchange\Mailbox\First Storage Group\Mailbox Database.edb” /t “E:\TempDefrag.edb”
    • Note the quotes around the path.

We ended up needing to figure out where eseutil dropped the temp database that filled up the system partition during the first run through.

A bit of tweaking in Search and we found it:


Both the RAW and EDB files were found in System32 under the %windir%. Note the size of the temp database at 23GB.

We removed the two temp files and re-ran the eseutil defragment process using the temporary file location designation and all was good.

You should use the temp location even if you have the space. On a separate drive the speed increase is worth the extra effort.
We have even taken the time to add another drive to the server just to use as the temp database location.

I believe you have incorrect space after /t in your syntax? Thats perhaps why it didn't use the specified location.

Thanks for the tip. I had the same problem until I saw your /t switch.
