Hotmail Stopped Working on My iPhone: Causes and Fixes

Why Hotmail stops working on iPhone

Even if your Hotmail was fine yesterday, it can fail today for a few predictable reasons.

• Saved password became invalid** after a Microsoft security check or password refresh.• The wrong kind of account type, such as POP or "Other", was selected instead of Outlook/Exchange and this might cause an error in syncing or logging in. * **iOS update conflicts** (particularly with major releases such as iOS 18) can break Mail/Outlook authentication or background sync. * Network issues: basically, Wi-Fi DNS glitches, captive portals, or cellular restrictions. * **Microsoft outage or server-side throttling**—rare, but it happens.
• Mailbox or iPhone storage full**, stopping new mail from downloading or sending.

The good news: you don't need to diagnose perfectly. The following steps are ordered from easiest to most powerful.

Microsoft sometimes invalidates old tokens after security checks.**Steps**

1. Settings → Mail → Accounts**
2. Tap your **Hotmail/Outlook** account
3. Click **Re-enter Password** (or if not presented remove and add it again).

If you have recently changed your password on another device, then you *must* update it here too.

• Steps**
1. Settings → General → Transfer or Reset iPhone**
2. Tap **Reset → Reset Network Settings**
3. Reconnect to Wi-Fi and then try Mail again.

-Fix 10: Check mailbox + device storageFor instance, when your Microsoft storage is near full, Hotmail may stop taking new emails; similarly, if iPhone storage is maxed out, Mail may fail to sync.

• What to do
• Delete large emails/attachments
• Empty Deleted Items & Junk
• Free iPhone storage: **Settings → General → iPhone Storage** ---

11. Fix: If Hotmail won’t send emails

Sending failures almost always relate to attachment size or SMTP rules.

• Keep attachments small: Outlook blocks large sends.
• If using manual setup, ensure outgoing server is Outlook SMTP:
• smtp-mail.outlook.com`
• Port **587
• TLS/STARTTLS on
• Authentication on.

If you didn't set anything manually, the delete/re-add through Outlook.com fixes SMTP automatically. ---

• FAQ: Hotmail Not Working on iPhone
• Q1. Why did my Hotmail suddenly stop working on iPhone? Usually because iOS updated, Microsoft refreshed server security, or your saved password expired. Most cases are fixed by re-adding the account as Outlook.com. (The Mac Observer)

Q2. Hotmail works on my computer but not on iPhone — what does that mean? Your account is OK; the iPhone Mail configuration is at fault. Delete the Hotmail account and re-add it using **Outlook.com/Microsoft Exchange**.

• Q3. Why am I not getting emails from Hotmail on iPhone? Fetch/Push may be off, sync window too short, or mailbox storage is full. Turn on Push and set Mail Days to Sync to No Limit.
• Q4. Why does Hotmail keep asking for my password? Microsoft might have invalidated your sign-in token. Remove/re-add the account, or re-enter your present password.
• Q5. Which is better - Apple Mail or Outlook app for Hotmail? Outlook application is more stable with Hotmail/Outlook accounts, mostly after iOS updates.

Q6. What if I still can’t log in even with the right password? You might be temporarily blocked for security. Log in via Safari, and complete any verification/reset prompts then try again on iPhone.

Q7. Hotmail won’t send mail from iPhone — why? Most likely an attachment too large or SMTP mismatch from manual settings. Re-add as Outlook.com or use Outlook app.

• Bottom line The universal quick fix when **Hotmail stops working on an iPhone** is: 1. Delete the account 2. Restart iPhone 3. Add it again through **Outlook.com / Microsoft Exchange That resets your server profile to Microsoft's current standard and clears 90% of Hotmail access issues. If you want, just tell me the exact error text that you see, such as "Cannot Get Mail" or "Password Incorrect", and I will map it to the precise fix.
