Hi @V K
I am pretty certain that your files will be accessible even after you have been disabled. This is true if your onedrive does not get deleted.

Question:
If a user creates a file on OneDrive, and shares it with others (giving them "Full Control" access) - and then the original user's account is disabled - do the other accounts with "Full Control" still have access to the files?
Answer:
As long as the drive still exists, yes.
