Most operators should use webmail instead
This is an advanced, one-time setup a Karibu administrator does for the whole workspace — it registers a Microsoft Entra application. If you just want to send from your own address, use the Connect your webmail (SMTP/IMAP) path instead: about 5 minutes, no Entra app registration. Microsoft 365 / Outlook also works over plain SMTP/IMAP (host
smtp.office365.com, port 587), so you rarely need this guide.Why you need this
For the same reasons you'd connect Gmail — inbox placement and reply rate are 3-5× higher when mail comes from you@yoursafarico.com than from a shared sending domain. If your business runs on Outlook / Microsoft 365 instead of Google, this is the path.
Current status
Outlook connect is live
The full Outlook send-from-your-mailbox flow is available now. Head to Settings → Mailboxes and click Connect Outlook to grant access via Microsoft — Karibu never sees your password, and the access token is encrypted at rest and revocable anytime from your Microsoft account. The steps below cover any Azure / Entra prep your admin may need first.
Before you start
You'll need:
- A Microsoft 365 / Outlook account you control
- Admin rights on that account — or someone who has them on standby
- ~15 minutes uninterrupted
- A password manager or notes file to temporarily hold the credentials

Open entra.microsoft.com — the Microsoft Entra admin center, where app registrations now live (the classic portal.azure.com still works too) — and sign in with the Microsoft 365 / Outlook account you want Karibu to send mail from.
Personal Outlook accounts work tooEven if you use a free@outlook.comaddress, you still sign in to the same Azure portal — Microsoft auto-creates a tenant called "Default Directory" behind the scenes the first time you log in.Screenshot reference: Azure portal home with the "All services" button in the top-left
