When trying to add a new user, I am receiving the following error “User has already been taken.”. What is the cause and how do I workaround this issue?

EZRentOut uses the email address of a user to uniquely identify a user. If you are getting this error, you may be trying to create two different users using the same email address. On rare occasions, it has been observed that two different companies may attempt to use the same email address to create users in their account. EZRentOut does not allow an individual to be a member of more than one company.
If you intend to ‘move’ membership to a different company, please contact support at info@ezrentout.com.
