Hello Daniel Schutte2,

Thank you for reaching out to the Microsoft community.

Based on the behavior described, this issue appears to be related to how the system processes the identity parameter when setting Out of Office (OOO) across multiple mailboxes. Since multiple administrators are experiencing this across different machines and browsers, it suggests a backend issue rather than a local device or browser-related problem.

One possible reason could be synchronization delays, especially if the affected mailboxes were recently modified or are in a hybrid environment (If there is any). In some cases, temporary service-side issues may also lead to inconsistent behavior when configuring OOO settings. Additionally, policy or permission conflicts might be preventing the request from processing correctly, particularly if multiple administrators are making changes at the same time.

Since this requires further investigation at the backend, I recommend contacting Microsoft Support for direct troubleshooting. The support engineers have access to system logs and synchronization data, allowing them to analyze the root cause of the issue. If needed, they can initiate a secure remote session to check the affected mailboxes and collect necessary logs for a deeper investigation. Should the issue require further analysis, they can escalate it to internal Microsoft teams for additional troubleshooting and resolution.

Contact the Microsoft technical support team through your organization's designated support channel or directly via the Microsoft 365 admin center. Here’s what your Office 365 Global Admin should do next: 

• Submit a Service Request: The Global Admin should create a service request with Microsoft support to get advanced technical assistance and diagnostics. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin.
• Find Your Microsoft 365 Admin: If you’re unsure who the Global Admin is within your organization, you can find guidance on locating them here: How do I find my Microsoft 365 admin? - Microsoft Support.
• Call Microsoft Support: For additional assistance, use this link to find the appropriate contact number: Global Customer Service phone numbers - Microsoft Support
• Contact a Reseller (if applicable): If your Office 365 subscriptions are managed through a federated partner or reseller and the Global Admin cannot open a service request, they should contact the reseller’s support provider. The reseller can assist with initiating the request and coordinating with the Office 365 support team.

I believe the details provided will guide you toward receiving the appropriate support and a resolution for this situation.

I would appreciate your understanding and coopetition!
