I'm going to have to let someone using Outlook help with that.
I thought I'd mention that we ask our members to avoid using
email addresses in (as) membernames, too.
You can PM (click the PM button) the site admin
(Grinler) under any of his posts & he'll make it possible
for you to pick a new name.
Someone is bound to know more of this problem
and post a reply, so be patient
and go ahead and pick a new name, too.
