Troubleshooting

This section outlines common issues you may encounter with the Mailbridge and how to resolve them.

Error when calling setFlag

If you encounter an error indicating that the setFlag method failed, it is highly likely that the Mail.ReadWrite API permission is missing for your app.

Ensure that your app has been granted sufficient permissions to read and modify emails in the configured mailbox. For more details on required permissions, refer to the Graph Mailserver documentation.

Problems with Shared Mailboxes

If you are using a shared mailbox, and the mailbridge is not able to read the mailbox, you can try to add extra API permissions to your application: Mail.ReadWrite.Shared
