large e-mail send / recieve problems with larger e-mails
Posted on 2014-04-30
We are using sbs2011 with exchange 2010.
We are having problems sending and receiving larger emails using outlook 2007. I understand the default server / exchange settings are 10mb.
I have been through this before supposedly changing the maximum sizes to 20mb, and I have used the exchange powershell to verify that indeed we have increased the settings to 20mb, but whenever we send anything over 10mb in size we get the NDR :-
"This message is larger than the size limit for messages. Please make it smaller and try sending it again.
Diagnostic information for administrators:
Generating server: SBS2011.domainname.co.uk
#550 5.3.4 ROUTING.SizeLimit; message size exceeds fixed maximum size for route ##"
If we break it down under the 10Mb it goes through just fine.
The granular e-mail accounts themselves show that they are all unlimited.
Can anyone assist in sorting out why we still have an issue, and perhaps allow us to verify where the restriction is still set?
