Set Up Work Email on iPhone or Android (Microsoft 365)

Category: Mobile Devices · Audience: Customers & Technicians · Est. time: 10–15 min

Summary

The recommended way to get work email on a phone is the Microsoft Outlook app, which supports Microsoft 365 security (MFA, conditional access) cleanly.

ℹ️ Your organisation may require the phone to be enrolled/registered or to use the Outlook app specifically. If setup is blocked, contact BBN Support — it may be a policy, not a fault.

Recommended — Microsoft Outlook app

1. Install Microsoft Outlook from the App Store (iPhone) or Google Play (Android).
2. Open it → Add Account → enter your work email address → Continue.
3. Enter your password, then approve the multi‑factor (MFA) prompt (Authenticator app, text, or call).
4. If prompted to register the device or install Company Portal / Intune, follow the prompts — this is your organisation's security requirement.
5. Done — mail, calendar and contacts sync in the Outlook app.

Built‑in Mail app (only if required)

1. iPhone: Settings → Apps → Mail → Mail Accounts → Add Account → Microsoft Exchange (or "Microsoft"). Enter the email, choose Sign In, and complete the Microsoft login + MFA.
2. Android: the native mail app varies; the Outlook app is strongly preferred for reliability and security.

If that doesn't work

• "Can't sign in / needs approval" usually means MFA isn't set up — see the *Set Up Multi‑Factor Authentication* article first.
• "Account can't be added" can be a conditional‑access / device‑compliance policy. Contact BBN Support.
• Wrong password after a reset? Update it in the phone and retry.

Prevention

• Use the Outlook app and keep it updated; keep the Microsoft Authenticator app installed for MFA.
