Microsoft Outlook log ins issue

Question

I use an authenticator app. It pops up multiple times per day to verify log in. I have called Apple. They ya it’s an authenticator issue and not an Apple issue.

Answer 1

Hi, I'm John!

You're not alone, many users are currently experiencing the same issue with Outlook. It appears to be a widespread connectivity problem. Impacted users may include, but are not limited to, iOS users.

You can check the official service status here: https://portal.office.com/servicestatus/ expand “Microsoft consumer products”and look for the Outlook.com section for details.

For now, please wait until Microsoft resolves the issue and try again later.

I really hope this information is helpful!

Answer 2

Frequent Microsoft Authenticator prompts usually mean that Outlook or the account is repeatedly re-authenticating, or that the sign-in flow is not completing cleanly.

For Outlook on iOS (personal Outlook.com/Microsoft account), there are two main approaches based on the provided information:

1. Use Outlook mobile itself as the sign-in method (instead of constant Authenticator prompts)
   • Open the Outlook app on the iPhone.
   • Tap the top-left Home icon.
   • Tap the Settings gear at the bottom left.
   • Under General, tap Accounts, then select the Microsoft account used in Outlook.
   • Tap Sign-in requests.
   • Turn on Allow sign-in requests.
   • After this, Outlook mobile can approve sign-ins directly or provide a time-based one-time passcode (TOTP) via Sign-in requests, reducing dependence on separate Authenticator prompts.
2. If Outlook is used as a one-time code generator
   • When a sign-in page offers Use a code, choose that option.
   • In Outlook mobile:
     1. Tap Home → Settings → Accounts → select the account.
     2. Tap Sign-in requests.
     3. Tap the code to copy it (codes refresh every 30 seconds).
     4. Paste the code back into the sign-in page.
   • Using this flow can help complete sign-ins cleanly and may reduce repeated prompts if previous attempts were failing mid-way.

If prompts continue very frequently, verify that each sign-in is actually completing (no “Authentication did not complete” errors) and that the device has stable network connectivity, correct date/time, and the latest versions of Outlook and Authenticator installed, as incomplete or failed authentications can cause repeated challenges.

If the issue persists even with correct setup and stable sign-ins, use the Outlook and Microsoft account support options (such as Microsoft Community or Outlook Forum on Answers) from the referenced articles to gather logs/screenshots and escalate.
