The simple easy way to handle this would be to deliver info@domain to a real
mailbox and setup Sally's Outlook accounts to include both her private and
her info@ accounts. You can even create folders for each of the info@
addresses and use filters to move the incoming emails into the correct
folder and a copy of the replies into the same folder. Then Sally can easily
see how many unread info@domain1 and info@domain2 emails she has to handles
and every time she replies to an email it would go out from the same info@
from: address.

Sounds to me like you are using info@ as an alias and in your circumstance
it should be a real mailbox. There is no reason why Sally cannot have
multiple accounts on the same server with different user names, signatures
and email addresses
