You need to elaborate on what it is you are trying to do.
I take it that you and your husband share one computer
but you have individual email addresses?
If privacy is not an issue, you can easily add more email
accounts: Tools, Accounts, Add.
If you don't want your emails and your husband's email
intermingled in the common Inbox, just set up two message
rules (filters) such as this:
1. Where the message is from the Husband account
move it to the His_Inbox folder
and stop processing more rules.
2. Where the message is from the Wife account
move it to the Her_Inbox folder
and stop processing more rules.
