We're using the following endpoint in Microsoft Graph APIs to send emails from users' mailboxes.
POST /users/{id | userPrincipalName}/sendMail
The POST request has a parameter called saveToSentItems that controls whether sent emails are saved in the Sent Items folder or not. We have noticed that when saveToSentItems parameter is False then the email is not saved to Sent Items but is saved in RecoverableItemsPurges folder. This unexpected behavior is not documented anywhere in the docs and we cannot figure out the logic behind it or is it simply a bug in Graph APIs?
Ideally, we don't want the email to be saved anywhere in the mailbox when saveToSentItems flag is turned off. Let us know how to achieve this.
