Microsoft Office 365 (Outlook)

Configuration Guide for Adding Microsoft Office 365 Mailboxes

The process is very simple and straightforward, as we have enabled adding MS mailboxes through OAuth. For a faster connection, ensure you are logged into the inbox you want to add, then head over to ClosersHQ on the same browser and follow these steps:

  • Click on 'Connect'.

  • Enter your mailbox password in the dialogue box (if it's not auto-filled), then click on 'Sign in'.

  • Next, click 'Yes' to grant all necessary permissions.

That's it. Your mailbox is connected. Switch on warmup on the mailbox and you're all set 🎉
