Hello @Phil Dando,
Thank you for posting your query on Microsoft Q&A.
Based on your message, it seems you are experiencing provisioning issues with one or two users. The error indicates that the user account is being skipped because the user domain is inaccessible with the credentials provided in Google Cloud / Workspace. Could you please confirm if the user domain is verified in Google Cloud? Are the users being provisioned using the same domain suffix?
It would also be helpful to compare the profiles of working and non-working users in Microsoft Entra ID. This comparison can provide insights into why the error is occurring. Additionally, check whether the affected user is a guest account or a normal user account within your tenant.
What attribute are you using to provision the users to Google Cloud—email or UPN?
After re-evaluating the user, if the issue remains unresolved, please try making changes to the user account by resetting the password and revoking the sessions.
I hope this information is helpful. Please feel free to reach out if you have any further questions.
