Error "FYI-2136 There is an issue with your Guest User setup. Please check your Guest User configuration in Microsoft 365 and try again" when running New Collaborate Status Check

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 Guest User configuration in Microsoft 365 and try again.
  • Guest User Security does not appear to be enabled. Please speak to your Microsoft 365 administrator

Note: Changes made to these settings may impact the ability for users to invite guest users to other Microsoft collaboration elements not used by FYI. If you are unsure on how to perform any of these steps please speak to your IT Professional before making any changes.

Cause

This could be caused by Microsoft 365 not being configured properly, or if there are additional non-standard settings in Microsoft Entra that have been configured. Refer to Setting up Microsoft 365 for New Collaborate.

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

Step 1 - Review the Guest Invite Settings

  1. Go to the Microsoft Entra admin centre https://entra.microsoft.com and log in as the Microsoft Administrator.

  2. From the menu on the left, click the External Identities dropdown and select External collaboration settings.

  3. In the Guest invite settings section, confirm the following option has been selected:

    ➡️Member users and users assigned to specific admin roles can invite guest users including guests with member permissions.

    To restrict the ability for users to share directly from the SharePoint Collaborate site, we recommend updating this directly within the site once you have completed the New Collaborate configuration wizard. Refer to How to restrict the ability for internal users to invite guests to SharePoint.

Step 2 - Check the Collaboration Restrictions

  1. On the same page (External Identities - External collaboration settings) scroll down to the Collaboration restrictions section.

  2. The settings should be set to "Allow invitations to be sent to any domain (most inclusive)". This is the default Microsoft setting. 

    Important: It is not recommended to select the option "Allow invitations only to the specified domains (most restrictive)."

Step 3 - Re-run the Status Check

Once you have reviewed and updated the settings, re-run the New Collaborate Status Check. Refer to Checking your New Collaborate Status.
