When a user has many SMTP addresses, 1 has to be a primary. I have clients that need to be able to send out email FROM any of the particular email addresses.
Problem: When a user adds the “FROM” field in Outlook, he/she should be able to choose which email address they want to reply with. If I have a@adb.com, a@def.com, and a@ghi.com as all valid email smpt addresses assoicated w/ my account and a@abc.com is the primary SMTP address, but I want to type a@def.com as my reply address in my FROM field. Problem is that Exchange automatically finds which AD account is associated w/ the email address, then it shows the resolved “Simple Display Name” in the from field. When this happens, the primary smtp address of the account that Exchangeresolved, is used and not the address that was typed in the FROM field. How do I get around this w. setting up extra mailboxes and Outlook profles.
