Please check this post might help you,
My aim to access Inbox Unread messages from FactoryMailGroup
Could you help to me ?
Ans)You can change the Properties for “Get OutlookMail Message” Activity as
- “Filter” with “FactoryMailGroup”
and for only Unread Messages you can tick the check box of “Only Unread Messages” properties.
Mark as solution if it works
Thanks
