New Collaborate Status Check error: "There is an issue with your Guest User setup."

Issue

When performing a Status Check in New Collaborate, the following error is displayed:

• "There is an issue with your Guest User setup. Please check your Microsoft Guest User configuration and try again."

Cause

This could be caused by Azure B2B not being configured properly, or if there are additional non-standard settings in Entra that have been configured.

For example, a domain restriction may be configured in a Global Policy, preventing users from adding guest user accounts from specific email domains e.g. Gmail.

Solution

Your IT Administrator will need to review the configuration settings in Azure B2B and Entra.
