Outlook 2019 and IMAP

Hi,

We've just upgraded a few of our desktops to use Outlook 2019, and the
configuration is different from previous versions. There doesn't appear to
be any ability to specify a username in addition to the user's email
address.

The username is different than the username specified in the email address.
I had read about setting auth_username_format, but the user login name is
"user" while the email address is user.name at company.com.

I've included below my dovecot -n config.

# 2.3.7.2 (3c910f64b): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.5.7.2 (7372921a)
# OS: Linux 5.1.16-300.fc30.x86_64 x86_64 Fedora release 30 (Thirty)
# Hostname: orion.inside.example.com
