Microsoft Transport Suite issues moving attachment more than 29MB in Exchange Server 2007/Windows Server 2008

Hello folks,

If you are moving from Lotus Dominio to Exchange Server and you are having some issues to move attachments larger than 28/29MB and you are also running Exchange Server 2007 on top of a Windows Server 2008, this kb was made for you 🙂

The issue is caused because IIS 7 has a default limit of 30,000,000 bytes and to change the default behavior we need to add a line to the web.config file containing a key named MaxAllowedContentLength with a value that is higher than the attachment that you are going to move.

The process is explained in this following kb: http://support.microsoft.com/kb/959955/en-us

Cheers,
Anderson Patricio
