Hi all,
I am a beginner in MSExchange server administration. I deleted few of the mail boxes and cleanes few mail boxes. But, the free space size of the harddisk remains the same. What are all the possible areas should i check to make sure that i've saved some space?

The same thing happens in VSS also. If you could tell me a solution for this also, it would be great.

Thanks in advance.

Hi, simply deleting mailboxes in Exchange will not free up disk space. This is because Exchange assumes (naturally enough) that in time it will require this "free" space again so it keeps it for itself! If you really want to get the disk space back,you must defrag the database using eseutil.exe. This is a comand line utility in the Exchange admin tools. Note, you need at least the same amount of space free as the database takes up, as Exchange makes a copy of the database while defragging it.

if you look at the mdbdata folder you will notice transaction log files that grows in time. each log file is 5 mb each and continues to grow. if you do not want to keep the log files (which i suggest not doing for the purpose of recovering easily during hardware failures but if all users download files into their personal folders, i think its ok) you can enable circular logging (reuses one log file, if it reaches 5 mb, instead of creating a new one, it reuses the same file). you can do this by opening system manager, servers/yourservername, right click on first storage group and check enable circular logging. btw, yesterday, i found out my entire mdbdata folder has blown to 7 GB due to transaction logs.

In regard to Answer 1, if you use the eseutil.exe
to find out the actual size of your information store, be sure to do it when you have a little time because in some cases it can take over an hour to run. Also, I think it stops all of the exchangeservices as well, so email wouldn't work while you're doing this. Hope this helps.
