When you try to receive mail that is over 10mb into an Exchange 2010 mailbox, the sender may receive this bounce back error.

#550 5.2.3 RESOLVER.RST.SendSizeLimit.Org; message too large for this organization ##

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.

Almost every business has a person in-house who is the “go-to” person to solve IT issues. You may even be that person in your business?  What OJ Networks often seen though is that if the issue is a complex one or if there more than just a couple of staff to support, then this person spends a lot of time trying to solve these issues, at the expense of the work they are paid to complete.

In cases like this, two of your staff are now not working on core tasks. This can also cause unwanted stress as they try to catch up on their paid work. Make no mistake – having an IT savvy person in-house can be fantastic for solving small issues, but if they need help with something that is over their skill level, then having a trustworthy IT professional to call makes sense. IT Professionals have either seen the problems before or can intuitively find the solution to new problems quickly. This allows your business to get on with what it does best and keeps your staff happy and productive.

Some other benefits of getting an IT Professional to look at your issues are that they might have a solution that you did not know about to an ongoing issue. Things like using DropBox to share documents between offices or with employees who are out in the field. Or installing an Exchange Server or Exchange Online Solution to benefit from the power of having your email, contacts and calendar that stays in sync with you everywhere.

If you are looking for a IT company to look after your business on the Sunshine Coast then give OJ Networks a call!
