Why I am getting "access denied" on an invitation?

Please make sure you aren't using multiple accounts on MindMeister.

The mind map has to be shared with the email address of your standard MindMeister account.

You will receive "access denied" if you try to access a map from an invitation email which is not shared with your standard MindMeister account.

Please make sure all mind maps are shared with your right email address.
