Question : Display the email address a sender used.

We use MS Exchange and MS Outlook and host 2 domains on our server. When an email arrives, I need to easily see what email address was used to get a message to me. For instance, someone sends an email to '[email protected]' and another email arrives that has been sent to '[email protected]'. Both emails arrive in my inbox, but all I can see in the 'To' column of Outlook is my name. To find out what email address each one was sent to, I have to study the message header and scroll down through the coding.

Is there a way of displaying the email address as it appears in the 'Internet Headers' of the messge?

Answer : Display the email address a sender used.

One last idea before this thread vaporizes.  Does adding the Email Account column in the view show you through which account (alias) the e-mail was received?  

Since you are using aliases to the SAME account, the above might not work because you are only polling one account.  The aliasing is done by the mail server to deliver multiple recipients to the same mailbox.  So you are only polling a single account and that is probably the one that will show up in the Email Accounts column.

So why not use rules?  Create an Inbox folder for each account and use a rule for each account to move e-mails addressed to a particular e-mail address in the To/Cc headers into the appropriate folder.  For example, for 3 aliases that end up in the same physical mailbox, you could have the following folders:

Inbox
  Inbox - Account 1
  Inbox - Account 2
  Inbox - Account 3

The first Inbox has to remain and would be a general inbox.  Each of the other folders are subfolders under that general Inbox.  Then you would define a rule that looks for your Account 1 e-mail address in the To/Cc headers and, if matched, moves that e-mail into the Inbox - Account 1 folder.  Depending on what other rules, if any, you want additionally exercised on those e-mails, you may or may not want to include the stop-clause in these organizational rules.

Then instead of looking in the headers to see to whom an e-mail was addressed in the To/Cc headers, they would already have been moved to the corresponding folder.  The one problem encountered with this setup is if you receive e-mails that do not have you specified in the To/Cc headers.  If someone sends you a Bcc copy of an e-mail, there is no e-mail address to check by the rule.  The result is any Bcc'ed e-mails will end up in your general Inbox folder.  The same for any e-mails where you are not in the To/Cc header since they are NOT used to specify the recipient of an e-mail.  The To and Cc headers are in the *data* of the body of the message and are not directly used to specify the recipients.  Separate commands are sent by the e-mail client that is an aggregate of all recipients in the To, Cc, and Bcc *fields* within the application's UI.  The To, Cc, Subject, and From headers in your outbound e-mails are data that YOU specified (and why spammers can put anything they want in those fields).  Listservers or bulk mailers, like for newsletters, may not include your e-mail address in the To/Cc fields and instead simply have a string that is the name of the newsletter.  You won't lose any of those e-mails.  They'll end up in the general Inbox folder.  But for those e-mails where the sender did specify one of your e-mail aliases to your mailbox, they will get reorganized into matching named folders in Outlook.

Of course, maybe you don't want your aliased e-mails separated into separate folders.  But then I have to wonder why you have multiple aliases on the same mailbox if you didn't somehow want them handled separate of each other.
