Microsoft Graph Custom Connector Refresh

JeffreyKelso — Tue, 09 Mar 2021 16:20:15 GMT

I have a custom connector that connects to Microsoft Graph in order to extract a daily report from a shared mailbox. The oauth works perfectly within Visual Studio and on the desktop application, at least initially. The problem comes when a refresh token is needed for a refresh by the on-premise gateway. The connector doesn't seem to be able to request and apply the refresh token process. Within Visual Studio I can edit the credential, hit refresh, and set it again to get a new refresh token, so I know the refresh function is working at least. I assume this is because there is nowhere to store the refresh token so that it can be used on the next data refresh in order to obtain a new access token. Has anyone been able to get oauth to work with Microsoft Graph using a gateway refresh? Should I instead use an Azure Function to get the data from Microsoft Graph so that I can store the last refresh token within a data store?
