Hi @P M
Thank you for reaching us!
I understand that you are trying to merge Microsoft 365 E5 Developer subscription and Azure subscription under work email.
To answer your question, the Microsoft 365 E5 Developer subscription and Azure subscription are two different services, and they cannot be merged.
Microsoft 365 Developer Program subscription is only for developing and testing your solutions independent of your production environment.
Thanks,
Akhilesh.
