Solution 1Recommended

Contact Microsoft Support via Microsoft 365 Admin Center

Since this issue often involves backend services or specific corporate account configurations, submitting an official support ticket is the most effective approach.

Community moderators and end-users cannot directly investigate backend logs or fix client-side architecture bugs. Support agents will need to look into diagnostic logs and account provisioning details.

1
Access the Admin Center

Log in to the Microsoft 365 admin center using your administrator credentials.

2
Navigate to Support

On the left-hand navigation menu, click on 'Support' and then select 'New service request'.

3
Submit Diagnostic Details

Describe the freezing and crashing issue in detail, noting that it happens during active conversations, and submit the request so Microsoft can investigate the backend logs.

Contact Microsoft Support via Microsoft 365 Admin Center
Corporate User Limitation: If you are a standard end-user, you will likely need to ask your company's IT administrator to submit this service request on your behalf.
