Dynamics 365 App for Outlook | Error when loading emails in Outlook | Error Details: TypeError: Object doesn't support property or method 'forEach'

Dear Community,


I am not sure if this belongs here, there is already a post in the Dynamics 365 community as well.

(3) Dynamics 365 App for Outlook error when loading - Microsoft Dynamics CRM Forum Community Forum


Has anyone experience an error while using the Dynamics 365 App for Outlook recently? And more importantly, any recommendation/idea on how to fix this issue?


Below some details:


I am experiencing the same issue but only on the local Outlook application on Windows 10, the Dynamics 365 App for Outlook in OWA continues to works well. See screenshots below. Note that the default browser in Windows 10 is Edge. I noticed the issue after updating the local Outlook app.

This must be related to the default browser used by the Dynamics 365 App for Outlook and the code in 10.js/app.js which the Dynamics/PowerApps team might would like to have a look into...

Any suggestion/idea how we could resolve this issue? 

For the moment, using OWA...

Thank you in advance,
