Constant delivery delays and undeliverables generated from

This question has suggested answer(s) This question has suggested answer(s)
I have 4 clients that are all on microsoft hosted email and are consistenly getting delivery delays and undeliverables when sending to our internal exchange 2010 environment. I can provide the destination domain, headers, and ndr's when requested. When I put the headers into the analyze headers section of the website I don't see the actual messages even making it to the destination domain only within the microsoft environment. It doesn't indicate any issues just shows delays in the world. Are there others experiencing this? What can be done about it to help our clients be allowed to send us email without issues. We don't have issues with any other clients that host there email either internally or someone besides microsoft. Thanks in advance.
