I'm developing a technical walkthrough for adding my employer's IMAP accounts to the Windows 10 native email app. Unfortunately, there doesn't appear to be any option to configure a 'Root Folder Path' or 'IMAP Path Prefix.' The app is also missing other related settings for 'Mailbox Behaviors.'
As a result, the test email account does not save copies of sent messages. Is there a workaround for IMAP, or are we stuck with POP?
