I need help to change the display email address and reply-to-email address used when I create and send calendar invitations from Outlook.

Here is my setup.

I am using Outlook 2013 that is connected to an Exchange server.

I have 2 email systems.

My main email system is NOT using Outlook.  All of my emails flow through, as an example, mainemail@email1.com

Outlook is used only for my contacts and calendar.  For this email let's call it calendar@email2.com

Right now when I send a calendar invite it comes from calendar@email2.com and the reply-to-address is calendar@email2.com

I would like the "from name" and "reply-to" name for all calendar invites to be displayed at mainemail@email1.com

My mainemail@email.com will redirect all calendar invites to calendar@email2.com

How can I configure Outlook to do this?

So to my understanding there are 2 different email systems: one handling the @email1.com, based on Postfix/sendmail/Exchange/<other mail server> and one handling the @email2.com based on Exchange.

If you add an accepted domain in your Exchange organization - @email1.com - then you'll be able to add the mainemail@email1.com address to the list of email addresses stamped on your Exchange mailbox. Following this, the recently added address can be specified as reply-to address (Primary SMTP Address). On the other email system, you'll have to use @email1.com as an internal relay accepted domain (similar to the notion described here) and configure a connector to send email to the Exchange organization for @email2.com. As for the forwarding itself - if that system is also Exchange - the 'targetAddress' attribute could be used, which will instantly forward the email to the 'calendar@email2.com' value that should be stamped inside (see this link); if a different email system, then the equivalent feature of 'targetAddress' should be used. 

Yet the whole setup is cumbersome to say at least. Could you give more details about what is it you're trying to achieve at a higher level ?

Thank you Albert for the info.  At a higher level all of my emails are received through @email1.com  which is not an Exchange server.  I prefer this email system over exchange.  I prefer exchange for the calendar and organizing my contacts.  What I am looking to achieve is to have one email to the outside world.  Currently I get meeting invites sent to @email1.com

Hi JF1313,

According to your description, I know that you want to let the recipients know all items are sent from @mail1 ,even if the calendars are sent from @mail2.

Based on my knowledge, if @mail1 is an Exchange Server, the method that Albert mentioned is the best.

 

Thanks
