Hi Rishi,
You can probably look at Outlook REST API
https://docs.microsoft.com/en-us/outlook/rest/get-started , it uses O-auth 2 for authentication, and is pretty straightforward to use. You just need to register an app on apps.dev.microsoft.com and provide Mail.ReadWrite permission to the app. And start consuming the API (You would have to write an object utilizing internal HTTP VBO) - https://msdn.microsoft.com/en-us/office/office365/api/mail-rest-operati…
Or else, you can use internal VBO - POP3/SMTP, bundled with Blueprism installation to manage mailbox. Although both of the methods require approvals from security teams since the access type is different. In case you're using POP3/SMTP or IMAP , you would need firewall rule updates as well as per their standard ports for BP machines - https://support.office.com/en-us/article/pop-imap-and-smtp-settings-for…
We're using the first method, and it works flawless.
Hope this helps.
