Move Emails - GraphAPI - Issue with Service Account and a shared Mailbox

Question

Hi,

We are trying an archiving strategy for our app, which require capability to move the emails to a separate Public folder (not well-known ones available but a newly created Folder in the mailbox) post processing.

We are using GraphAPI SDK.

Email message Move API seems to work fine for a service account and for it's own mailbox, but same API doesn't work for the shared Mailbox to which service account have Read and Write access.

API under consideration

Any pointers are highly appreciated.

Thanks.
