What you’re seeing
- The iPhone shows "Unable to verify account information" after entering the work email and password.
- The setup screen repeatedly returns to the password field.
- Signing in with Microsoft opens a page that fails or goes blank.
- The same account works in the Outlook app or on the web.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- Microsoft 365 has turned off basic authentication, and the account is being added with an old method.
- Conditional Access policies require approved apps, so the native Mail app is blocked.
- Multi-factor authentication is required, but the sign-in flow did not complete correctly.
- Exchange ActiveSync is disabled for the user or the organization.
- Autodiscover DNS records are missing or point to an old server.
Why it matters
When staff cannot set up email on their phones, they miss customer messages after hours and while traveling. They may work around it by forwarding mail to personal accounts, which bypasses company security and retention. New hires may spend their first day unable to access work email on the go. For owners and managers who need fast responses, it can cause missed opportunities and slower decision making.

Frequently asked questions
Why does it work in Outlook but not iPhone Mail?
Your company's Microsoft 365 policies may only allow approved apps, or iPhone Mail may be using a sign-in method that is no longer supported.
Is it safe to use iPhone Mail for work?
It can be, if set up with modern authentication and allowed by your security policies. Many businesses prefer the Outlook app for extra protection.
Can you get work email onto our iPhones without us bringing them in?
Yes, a certified US engineer reviews the account and policies in a remote secure session, and you pay only when resolved.
