  • You need to clarify what you want to achieve. Mailbox Database size automatically increased when mailboxes in it grows in size.

  • Hello,

    Mailbox Database size increases by it's own when the mailbox sizes are increased. So, there is no point in increasing the size of the database. The following cmdlet can show you the size of each databases in the mailbox server

    Get-MailboxDatabase -Status | select ServerName,Name,DatabaseSize

  • Hello Paul,

    Good Day...

    In Exchange 2010 Standard Edition is practally limited to 1TB Mailbox Database, but this is enforced by a Registry key. you can find this key here: 

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\\Private-GUID    

    The GUID of a particular Mailbox Database can be retrieved using the following Management Shell command:     

    Get-MailboxDatabase -Identity "" | FT Name, GUID    

    Change the "Database Size Limit in GB" DWORD value into the desired size.     

    Please note that this is only an acceptable configuration if you're using multiple copies of the Mailbox Database!

  • Hi,

    Please see best practices for mailbox database size in Exchange 2013:

    Standalone mailbox databases (no DAG): Recommended max of 200GB per database

    Highly available mailbox databases (DAG): Recommended max of 2TB per database

    More information: https://technet.microsoft.com/en-GB/library/ee832792(v=exchg.150).aspx

    You don't need to increase the mailbox database size in Exchange 2013. The edb file will continue to grow as more email data is stored. 

    Thanks.

  • Hi,

    A mailbox database is a unit of granularity where mailboxes are created and stored. A mailbox database is stored as an Exchange database (.edb) file. 

    Based on my knowledge, across the lifetime of an Exchange database its size will grow as the number of items it contains grows, the database file (.edb) will increase in size as necessary.

    In addiction, if you find the size of database is too big, you can perform an Window Server backup to truncate the log files. To control the rapid growth of edb files, you can enable archive on another mailbox database.

    Regards,

    David

  • Hi,

    If you mean that you want to increase the size of mailboxes inside the mailbox database rather than the mailbox database then you can do this at either the mailbox database level to apply to all mailboxes in the database or at the mailbox level to apply to just to the one mailbox.

    To apply storage quotas to a mailbox:

    To apply storage quotas to all mailboxes in a mailbox database:

    https://technet.microsoft.com/en-us/library/jj150580%28v=exchg.150%29.aspx

    Thanks.
