NUS IT has enhanced recently improved our Zoom Single-Sign-On integration recently.   If you had previously registered for a   personal   Zoom account with using your   NUS email address previously, it will may affect your eligibility access to use Zoom services such as Zoom Meetings, Zoom Chat, and other NUS-associated Zoom services that are associated with NUS. 

To resolve this

issue, you need to terminate your personal Zoom

account

that uses your

NUS

email address.

Once you have terminated your personal Zoom

account, a corporate Zoom account will be automatically created for you

by the next day.

Before

starting this process, please ensure you

won't need to use Zoom

services for

the rest of the day.

Q4. Error Message: Sorry, but we're having trouble signing you in.
AADSRS50105: Your administrator has configured the application Zoom to block users unless they are specifically granted ("assigned") access to the application. The signed in user 'yournameoruserid@nonNUSemaildomain' is blocked because they are not a direct member of a group with access, nor had access directly assigned by an administrator. Please contact your administrator to assign access to this application.

The error message indicates a Sign In attempt with <'yournameoruserid@nonNUSemaildomain>.

Your NUS Zoom account should be <staffID@<NUS-ID@nus.edu.sg> or <studentID@u<NUS-ID@u.nus.edu>, hence the error.

To prevent your device from signing you in automatically with <'yournameoruserid@nonNUSemaildomain>, 
use a different web browser or use the incognito/private browsing mode.
