Home Forums Networks & Cross-Platform Networking New ISP - New Email Address

I've changed ISPs and now have a new email address. In Apple mail I have not deleted the old account as I want to keep the contents.

I note that, if I go into Mail>Preferences>Accounts, I can enable the old account and see all the email. If I enable the new account, none of it is there…which I would expect.

I have not yet quit the old ISP and am wondering if I will be continue being able to see the old mail after I quit them. I think I should as I assume the mail is stored on my drive. However, I'd like to know for sure.
