I'm 'suddenly' getting this message error from Exchange/Outlook when trying to send an attachment greater than 9 MB although I've configured my Exchange 2010 server to use a 30 MB limit everywhere (I've done all of this: http://exchangepedia.com/2007/09/exchange-server-2007-setting-message-size-limits.html
Yet I keep getting this 9MB error!? Anyone have an idea why and how to solve this?
I'm also using a Watchguard firewall but it seems to be the error gets triggered while still this side of the firewall ...
Any help is appreciated!
