Today I got a call from a person who is trying to send us an email from outside our organization. He said it keeps getting rejected. The first thing I do is check our spam server and all three emails were clean so it sent it to the 2010 SP1 Exchange server to be processed. I went to the Microsoft Exchange Troubleshooting Assistant, entered in the email address in the senders box, unchecked the sender id box and then set the correct time window the emails came in. When I click next it only give me one entry. What happened to the other two emails? I went back to the spam server to find why it was rejected and it said it was rejected by the exchange server because the message size is two big. My question is why isn’t the Microsoft Exchange Troubleshooting Assistant giving me all the clean and rejected email? I also tried most of the options in the drop down of the message id box and no luck.
