I greatly appreciate your help.  I do no understand your directions.  In reading what you are asking me to do, it seems you think I do not have multiple "from" email addresses.  I already have 5 accounts.  For instance:

[email address removed]

[email address removed]

[email address removed]

[email address removed]

[email address removed]

[email address removed]

My issue is that not matter what company file I am logged into, QB always wants to send from the same default account, in this case, [email address removed]

It is confusing and embarrassing when a client mistakenly gets an invoice from company 2 but it is sent from company 1 email.
