A Microsoft file hosting and synchronization service.
Hi BISWAJIT BISWAL,
I'm sorry to hear that you've lost access to your Gmail account.
If your Microsoft 365/Office license is linked to a Microsoft account that uses that Gmail address, it usually cannot be transferred directly to a completely different Microsoft account. However, if you're still signed in to the Microsoft account on your laptop, you may not need to transfer anything.
In many cases, you can simply add a new email address to the existing Microsoft account and make it your preferred sign-in address while keeping your Office license, files, and subscriptions associated with the same account.
Could you let us know whether you are still signed in to Office on your laptop (for example, Word or Excel), and whether you can access your Microsoft account settings? That information will help us point you in the right direction.
