I need urgent help, please advice

I graduated in june 2024, i received email the other day saying

" Your access to McMaster’s Microsoft 365 and Zoom accounts will expire on February 4, 2025, as you are no longer an active student. After this date, your accounts and all associated data, including emails and documents, will be permanently deleted. This may also affect access to external accounts, such as social media, if they are linked to your McMaster email."

does that mean i wont have access to my mcmaster email address anymore? I applied to grad school I(the one at mac) and i put mac email on my application.

what do I do to keep it? please advice

thanks
