I use outlook for my bussines mail.
I recently added another outlook account for another email address.
But the incoming mails of the new address keep going to the inbox of the 1-st one.
Up today I use to open my work mail on yahoo.com
I created an outlook account on my PC and linked with mywork mail
The synchronization lasted some hours, later my mailsstarted deleting from my account. first they were sent to trash than delete.
