Hello,
We have 2013 Exchange consisting of 2 CASs and 2 MBX servers spanning two locations via VPN, 1 of each server in each location. We are hosting exchange for an outside domain, and have just transferred them into our organization within the last month. There are two users who consistently have messages stuck in the "Retry" status in the submission queue. Not all of their messages, but usually 2-4 are stuck and eventually kicked back to them.
I have read other forums about a potential issue with conversion to RTF. I have forced the queues empty and attempted this fix, but within a week the users had messages stuck again.
Has anybody run into this and possibly found a fix?
