I accidentally deleted my profile and now I cannot access my old emails. How do I recover my profile? Or how can I access my OST file with my new profile?

HOW did you delete that data ? Just by using the delete button?
Have you checked the content of the refusebin if that data is still there, because - if so - you can restore it from there.

Success

Yes, Crede

Thank you for your reply but I already exhausted my options, so I am looking for an option to access the encrypted ost file that is orphaned by me deleting my profile.
