In order to create a new account, you need to use a valid email address. But what exactly qualifies as a valid email address?
A valid email address is one that has a registered domain.
For example, glenraven.com is a registered domain, so any email address with the glenraven.com domain will be considered valid. If a domain like hotmail.com has not been registered with the app, you will not be able to use an email address with hotmail.com to create an account.
How do you register a domain?
Only a tenant administrator can register a domain. When the tenant administrator registers a domain, any email address with that domain name can be used to create an account.
But my email domain has not been registered, what do I do?
If your email domain has not been registered and you don't want to wait for the tenant administrator, you can use the secondary email feature.
For example, if your email is firstname.lastname@example.org and hotmail.com is not a registered domain, you can use a nonexistent email address for the primary email. You can enter email@example.com in the primary email field because glenraven.com is a registered domain and then enter your real email, firstname.lastname@example.org in the secondary email field. The primary email will grant you access to the app but all emails will be forwarded to your secondary email.
