Dear Ray_594,
Good day. Thank you for posting to Microsoft Community.
Based on the information you provided, I did a similar test on my end, but it did not reproduce the issue you mentioned. Since this issue occurred on multiple users, I'm afraid this issue needs to be investigated from backend side via remote assistance and collect background logs.
As this forum Community has limited resources and we can give you some general troubleshooting methods. For you get more professional advice and assistance, I sincerely recommend you contact your administrator in your organization and let him open the support ticket to the relevant team: Get support - Microsoft 365 admin | Microsoft Learn. The backend support team has more permission and resource than us, and they have Escalate channel to escalate your issue to check more and collect log reports for the root cause.
Thank you for your patience and time.
Sincerely,
Claire | Microsoft Community Moderator
