Hi, Have you check individual send mail size limit Recipients | Mailbox -> select mailbox | Properties | Mail Flow Settings tab | Message Size Restrictions. Regards

Hi, Simply use this method and I hope you will get done. http://blogs.technet.com/b/sbs/archive/2008/10/28/how-do-i-change-message-size-limits-in-exchange-2007.aspx Regards.

Hi Palohornay, In Exchange 2007, there are many kinds of limits, such as global limits, connector limits, server limits and user limits. Based on your description, you have already checked out the global limits, connector limits and ADsiteLink. So please check out your server limits and user limits. Check out the server limits: Set-TransportServer and the required switches and parameters. Check out the user limits: Set-Mailbox –Identity User –MaxSendSize the limit you want to . And for detail, you can refer the following article, http://www.msexchange.org/articles-tutorials/exchange-server-2007/management-administration/exchange-2007-message-size-limits.html If you have any questions, please feel free let me know. I am glad to have a further discussion with you. Best regards, Yang
