Newbie to the forum, I appreciate any input on this issue..
So I have a user who has an alias attached to his Exchange account profile, Lets say that his primary SMTP account is email@example.com and his alias is firstname.lastname@example.org.
We have an automated process that uses this alias, email@example.com to send email once a process is completed to a large group of users..
If a recipient creates a rule that moves the message sent from this alias, firstname.lastname@example.org, to another folder (the rule is based on the explicit email address not friendly name) the rule works appropriately.
What we have found is that when the user is sending from his primary email address, email@example.com, the rule is executing on that address as well.
Are you using the rule for mail "with specific words in the sender's address"?
I have not tested it here, but based on how aliases work, yes, it is probably expected behavior because that address is tied to the mailbox and exchange only recongizes the SMTP, not the secondary addresses.
Does the automated process go through a SMTP server and add an internet header to the rule? If so, use a words in the header rule and look for the alias as the words.
