Your York email address was likely used to create a standard Zoom account.
You will be presented with the error Your email domain has been claimed.
You may have previously registered for a Zoom account and when you did, you used one of your York University email addresses (if you have more than one). Upon trying to login via the SSO option, as outlined in our Signing in to Zoom section, York University's Zoom account will need to reconcile that email to its own account. The issue arises because you have a York University email that is registered as a standard Zoom account.
In the future, when logging in to your York University Zoom account, you will need to ensure that the proper steps are being taken during the login phase. Please refer to the following information related to proper logon practices in our Signing in to Zoom section.
Do not use your York University email address when creating an account through Zoom. Your York University account already exists through our licensing arrangement and you only need to login correctly to gain access to it. If you have, or if you are in the process of signing up for a Zoom account, and you use any of your York University emails (if you have multiple) to do so, then you will be confronted with this issue in the future.
It is important to ensure that if you want a separate Zoom account for non-York University activities, please use another email such as Gmail, Outlook, etc.
Always ensure that you have logged out of your non-York University Zoom accounts when you go to use your York University Zoom license. Zoom has a helpful page on Signing out and switching between accounts. Please ensure you do this if you are on a public or shared computer.
If you are still experiencing login issues. You can take the extra step to log out of all of your current sessions by going to your Zoom profile dashboard (https://yorku.zoom.us/profile). It is the last option at the bottom of the page, titled Sign Me Out From All Devices. Once logged out of all of your devices, please try to login properly via SSO, as prescribed in our Signing in to Zoom section.
