I have developed some VBA that is intended to create an auto reply to a correctly formatted message. However step one of the process is to check the senderemailaddress and I am having trouble with senders from my own domain. Instead of the senderemailaddress coming in as username@mydomain.com it's coming in as something like: "/O=EXCHANGELABS/OU=EXCHANGE ADMINISTRATIVE GROUP (FY....LT)/CN=RECIPIENTS/CN=5959...E-USERNAME" How can I get the normal format username to test for validity
