Hi @Julien_RENAUD and thanks for the mention! Yes, we’re still working with Microsoft on improving our Teams integration; I’ll make sure to keep you posted as soon as I have an update to share.
Could you tell me (or our support team) more about the error message you’re getting?
I would also advise you to take a look at these integrations built by Microsoft, looks like they could be useful to integrate Asana with Sharepoint (Integrating MS SharePoint with Asana)
