Hello Rob,
That sounds like a good work around for the same issue but for my problem the environment variable is stored in each user's mailbox database for the server they need to connect to and this can change. So I need the email message bodies in their mailbox databases to have the URL link with the computed formula. This way every time they click the link it recomputes the correct link before making the connection to the correct address. This will allow it to continue working if the address changes.
I appreciate the idea and might be something to consider using in the future if a slightly different scenario.
Thank you,
Larry
