Microsoft has announced that it will be doubling the storage provided to 50GB from the current 25GB provided. Most users probably haven’t reached the ceiling of 25GB yet however it makes what is already a very attractive enterprise-grade email solution even better.

The mailbox size will be automatically implemented so Exchange Online Users will not have to do anything in order to benefit. If you are currently holding your old emails in a local archive PST, it might be a great time to upload all that content into the cloud so it is easily accessible from all your devices.

Your Exchange 2010 server may need a few settings changed if you want to receive mail of this size.

Due to the way Exchange routes emails we found the following settings helpful if you are using a facility such as popcon to download incoming mail.

  1. Organization Configuration ->Hub Tansport.
    Go to Global Settings -> Transport Settings
    Set the Maximum send and receive size to KB values that suit eg. 20480 for 20mb or 51200 for 50mb
    Exchange increase receiv
  2. Go to Server Configuration ->Hub Transport
    Go through the receive connectors one-by-one and right-click -> Properties
    Exchange Receive Connector
  3. Set the Maximum message size to a size that suits such as 20480 for 20mb and click OK. DO this for all the receive connectors unless you have a special one that you use for a certain purpose and needs to remain lower.

Now the larger messages from outside your organisation should get to their destination mailboxes in your Exchange 2010 Server.
