Hi Bryan Alfonso!
I'm Shakiru and Im glad to help you :)
Yes, a user with an E3 license will still be able to access a SharePoint site even if you disable their mailbox using the disable-mailbox function.
Disabling a mailbox using disable-mailbox primarily affects email functionality. It removes the user's mailbox and email features but doesn't directly impact their SharePoint access permissions.
I hope this helps!
Thank you
Best Regards
