I searched thru other posted questions and I find similar postings, but none of the noted resolutions worked for me.
I am trying to send a 17 MB attachment to my external address. But when I send it I get a '5.3.4 Message size exceeds fixed maximum message size'
The Global Settings and the Send Connector of the Hub Transport are set at 30720 kb. There are no size limitation on the invididual mailboxes
Any ideas on what I overlooked?
