[Skunkworks] Removing White Spaces in Exchange 2010 Mailbox .

Hi , I have an Exchange Server 2010 which has a mailbox database of 320 GB handling about 40 Accounts . I have tried deleting and archiving files from the accounts but the Database is still getting bigger . My hard drive has only 20 GB of free space left and hence I have to get a solution asap . My question is it safer to Create a New database in a different partition and move the accounts there or should I de fragment the current database ? Thanks,Charles Sent from my BlackBerry®
