Thanks Sebastiaan for the reply.
These steps are well noted during the logging process, however, the issue persist with same log being sent to Intune portal.
Although, reading the above guide, found some interesting note:
" Existing account
There's a known issue where there's a pre-existing, unregistered account, like email address removed for privacy reasons in Microsoft Edge, or if a user signs in without registering using the Heads Up Page, then the account isn't properly enrolled in MAM. This configuration blocks the user from being properly enrolled in MAM."
Will check and test if this is my case.
Cheers!
