How to retrieve the emails from a Public Folder

Public folders are not supported in the Graph API.

Code: ErrorItemNotFound. Message: The specified object was not found in the store.

Issue: In older versions (for example, 1.11.1 or 1.14.1), the Send Mail activity intermittently fails if multiple attachments are added to an email. The error message displayed is: "Code: ErrorItemNotFound. Message: The specified object was not found in the store."

The error occurs because the activity sends two separate requests to the Graph API. The first request creates the email object and adds the first attachment, and the second request appends the second attachment. In some cases, the second request is faster and the Graph Explorer doesn't have time to create the mail object before trying to append a second file.

Solution: We recommend you upgrade to a newer version of the package or surround the Send Mail with a Retry Scope activity.
