I am running CRM 2011 with the latest service packs and rollups. I have the email router configured to the best of my knowlege correctly using Office 365. When I attempt to send an email I look in activities at the email and I have "this message has not yet been submitted for delivery". I have searched high and low for an answer. The email router tests fine on all accounts, everything seems to be fine, and just last night while trying to troubleshoot I got a stream of 5 emails sent from CRM, but then after that nothing, all pending again.
I am at a loss and would love it if someone chould show me the err of my ways. I need this to work and I am truly sick of wasting time trying to make it work.
