Generally email that’s tied to your school or job is only active as long as you are a student/employee there, and given how many services don’t let you transfer email accounts at all even if you know you’re about to lose access and start migrating away you might not be able to.

Best practice is to separate out business, personal and academic into separate accounts and separate devices. No personal crap distracting you from your studies, no personal stuff that might endanger your job on your work email, and no sharing your personal email with randos at your job
