Migrating to Outlook 365

Mike Accola 1 Reputation point

I am running an old local copy of Microsoft Office Home and Business 2016 on my home computer. This software has treated me well. However, I am looking to move into the modern times and purchase a Microsoft 365 subscription.

What is holding me back is my old Outlook email. I am still pushing/pulling my email from comcast using SMTP/POP. Yeah, I know that is archaic. The problem is that I have tons of emails that go back 18 years that I cannot afford to lose. It is a treasure trove of information.

Is there any way I can move onto a Microsoft 365 subscription, yet still have access to my old emails? Any suggestions would be welcome.
