I have archieve the mail from outlook client. But the database of exchange server does not get reduce. Any one suggest wht is the problem? Rgds ArunArun Khatri

Archiving mails will not reduce the Exchange server DB size...it will only create whitespace.

This whitespace will be used for writing any new data. You will have to perform offline defragmentation to gain that whitespace.

Hi there, When data is removed from exchange mailboxes the database size in Exchange Server does not decrease. What happens is after online maintenance occurs in Exchange 2007 these deleted items turn into 'white space'. This white space is then used for any new data, rather than increasing the size of the EDB. You can see the amount of whitespace in your databases by looking for Event 1221 in the Application Log in Event Viewer. If you think you have unncessary amounts of white space in your database you can perform actions to fix this, which will decrease the physical size of your edb file. The first is offline defragmentation - however I would not recommend this and it is especially unncessary with Exchange Server 2007+. The second method is what I recommend and causes minimum downtime to both users and Exchange Server. This process is simply moving mailboxes to a new database. Exchange Server 2007 Standard allows for 5 databases, so if you have one free, simply create a new database, move all mailboxes and then delete the old one. This will remove any white space 'bloat'. Remember white space is part of a healthy normal Exchange database, sometimes if the white space amount is simply too large however, it does make sense to perform steps to reduce it.
