We need to search mails in Sent Mail
folder. Currently it is searching in Inbox
alone. What is the call we need to use for searching mail in all folder or the Sent Mail
folder?
Graph API gives support to the outlook api. If you are interested in Graph API then try this.
GET /me/mailFolders('SentItems')/messages?$select=sender,subject
You can use well-known folder names such as Inbox, Drafts, SentItems, or DeletedItems to identify certain mail folders that exist by default for all users.
