Zoom Events - Speakers unable to join the lobby

[jgriffith26]

I have a few speakers that have recieved their speaker ticket emails. They are able to get registered but when trying to join the lobby they get the message "This Zoom event ticket is associate with a different Zoom account than the one you've logged in to. To join the Lobby, please switch to the Zoom account used to get the ticket."

The only thing is both speakers say they are using a Zoom account with the same email address...

Any ideas on how I can fix this?

Hi @jgriffith26 

These are Guest Speakers outside of your Zoom account (or organization), correct?

Did they have Zoom logins already?

As a test - could you ask them to LOG OUT of their client before clicking the speaker invitation, then click the speaker invitation, then login again when prompted. 

Do you know if your Guest Speakers are users INSIDE a different Zoom account (a different organization in Zoom)  - maybe using Single sign-on (SSO)?
