Display full/real email address from Lotus Notes?
Solution 1:
When you do show details, it should so an expanded To and From under the regular heading and display the whole address. If it's another Notes user, the address will be the Notes canonical format though and not the @whatever.com format. (Not sure if you need @xxxx.com address when you say 'full email address' or if you just need an email address that Notes will recognize') It'll be like JOE BOB/XXX/COMPANYNAME if it's another Notes user and not an internet address.
You can also just hit reply and it'll fill in the address. Then hit esc to cancel the reply.
You didn't mention which version of Notes, so I'm assuming 8.5.x
Solution 2:
I'm using DWA, so YMMV, but I have a "More" menu that has a "Show MIME Header" command, and that shows the [email protected] address even when "Show Details" shows only the JOE BOB/XXX/WHATEVER form:
