How To Reset Email On iPhone | Stop Mail From Misbehaving

Mail can go from smooth to stubborn in a hurry. One day it’s fine, then it’s stuck on “Connecting,” showing yesterday’s inbox, or refusing to send from a perfectly good address.

The fix isn’t guessing. A solid reset is a ladder: start with tiny resets that don’t touch your account, then step up only when you need to. That keeps your setup intact and saves time.

What “Reset Email” On iPhone Means In Real Life

iOS doesn’t offer one big “reset email” switch. People mean different things when they say “reset,” so it helps to match the fix to the symptom.

• Sync refresh: the account is signed in, but new messages don’t show up.
• Login refresh: the provider keeps asking for a password, or rejects it.
• Account rebuild: sending fails, receiving fails, or server details are off.
• Connection reset: Mail works on one network but not another.

You’ll see all four paths below, in the order that makes the most sense.

Two Checks That Save You From Resetting The Wrong Thing

Sign In On The Web First

Open Safari and sign in to your email on the provider’s site. If the web login fails, Mail won’t be able to sign in either. Fix the account login first, then come back to the phone.

Look For A Stuck Outbox Message

Open Mail, tap Mailboxes, then check Outbox. One failed send can keep retrying and make Mail feel broken. Delete the stuck message or open it and resend after you reconnect.

Start With Light Resets That Don’t Touch The Account

Force-Quit Mail And Open It Again

Swipe up to the app switcher, flick Mail away, then relaunch it. This clears a hung sync session and rebuilds the mailbox view.

Toggle Airplane Mode

Turn on Airplane Mode for about 10 seconds, then turn it off. This resets Wi-Fi and cellular links without changing account settings.

Restart The iPhone

A restart clears background network sessions and cached tasks that can get stuck. If Mail has been open for days, this can break a repeating failure loop.

Resetting Email On an iPhone After A Password Change

Password changes are a common trigger for Mail issues. If you updated your password, turned on two-step sign-in, or changed a work password, Mail needs a fresh sign-in.

Use The Password Prompt If You See It

If Mail pops up a password window, enter the new password and save. Then open the inbox and pull down to refresh.

Re-enter Credentials In Settings

Go to Settings, then find Mail. On some iOS versions you’ll tap Apps first, then Mail. Tap Mail Accounts, choose the account, and update the password if you see a password field.

If the account uses Google or Microsoft sign-in, iOS may open a web sign-in screen. Finish the sign-in, complete any code step, then return to Mail.

Watch For App Password Rules

Some providers require an app password when two-factor sign-in is on. If your normal password works on the web but Mail keeps rejecting it, check your provider’s account security page for app password options.

Know The Difference Between Mail Accounts And Your Apple Account Email

People mix these up. A “Mail account” is the inbox you add inside iPhone settings (Gmail, Outlook, iCloud Mail, work Exchange, custom IMAP).

Your Apple Account email is the address used for Apple sign-in and receipts. Resetting Mail won’t change that Apple sign-in email. If your goal is only to fix Mail syncing or sending, stay in Mail account settings.

When A Full Rebuild Is The Right Reset

If webmail works but Mail won’t send, won’t receive, or keeps looping through the same error, rebuilding the account on the phone is often the clean fix. It forces iOS to fetch fresh server settings, renew sign-in tokens, and rebuild the local mailbox index.

This does not delete your mailbox from the provider. It removes the account from the phone, then adds it back.

What You Might Lose On The Phone Only

Most email lives on the provider’s server and comes back after you re-add the account. Two things can be local only: drafts saved “On My iPhone” and mail stored in a local mailbox.

If you use local storage, move those items into a server folder (like Inbox or a custom folder) before removing the account.

Remove The Account

Follow Apple’s steps for removing and adding Mail accounts: add and remove email accounts on iPhone.

1. Open Settings.
2. Tap Mail (or Apps → Mail), then tap Mail Accounts.
3. Tap the account you want to reset.
4. Tap Delete Account or Sign Out.

Add The Account Back

1. Return to Mail Accounts and tap Add Account.
2. Select your provider (iCloud, Google, Microsoft Exchange, Yahoo, or Other).
3. Sign in and complete any two-factor steps.
4. Choose what to sync (Mail, Contacts, Calendars, Notes).

Open Mail, wait a minute for the first sync, then test sending and receiving.

Pick The Reset That Matches The Symptom

Use this comparison to avoid doing more than you need. Start at the top and move down until Mail behaves.

Reset Option	Best For	What Changes
Force-quit and reopen Mail	Mail stuck loading, frozen mailbox view	No settings changed
Airplane Mode toggle	No refresh after switching networks	Network radios reset
Restart iPhone	Errors repeat after each open	Background sessions restart
Re-enter password	Password changed, login rejected	Credentials refreshed
Turn Mail sync off then on	One account won’t update, others do	Mail toggle restarts sync
Remove and add the account again	Send/receive fails, tokens stale, settings off	Account rebuilt on device
Reset Network Settings	Mail fails after VPN or Wi-Fi profile changes	Wi-Fi, cellular, VPN settings cleared
Verify provider status and blocks	Webmail works, Mail still rejected	You confirm outages or security blocks

Turn Mail Sync Off Then On

If you want a reset that doesn’t remove the account, try flipping the Mail toggle for that account. This stops syncing, then restarts it clean.

1. Open Settings → Mail → Mail Accounts.
2. Tap the account.
3. Turn off Mail.
4. Wait about 15 seconds, then turn Mail back on.

Open Mail and refresh. If messages flow again, you’re done.

Fix Sending Issues After You Reset

Receiving and sending are separate paths. You can see new mail and still get “Cannot Send Mail.” That points to outgoing server settings, authentication, or a blocked connection.

Work through Apple’s sending checklist here: If you can’t send email on your iPhone or iPad.

Confirm The Correct “From” Address

When you compose a message, tap the From field if it appears. If you have multiple accounts, it’s easy to send from the wrong address, then watch it fail because that account can’t send.

Check SMTP Authentication

Go to Settings → Mail → Mail Accounts, tap your account, then tap SMTP under Outgoing Mail Server. Your primary server should be on, and it should use your email login, not “None.”

Recheck Provider Security Alerts

Some providers block sending after a new device sign-in, a new IP address, or a security change. Sign in on the provider’s website and clear any “new sign-in” warnings, then try sending again.

Provider-Specific Reset Checklist

Most accounts add with one sign-in screen. If your provider adds extra security layers, a reset goes smoother when you match the provider’s rules.

Email Provider	What To Check	Fast Fix
Gmail / Google Workspace	Web sign-in completes and permissions are granted	Remove account, add again, finish the web sign-in
Outlook.com / Microsoft 365	Two-factor step and device prompts complete	Re-add and approve the sign-in on your Microsoft account
Exchange (work email)	Password rotation and device compliance prompts	Re-add after updating password, accept device prompts
Yahoo	App password requirement after security changes	Create an app password, then sign in again
iCloud Mail	Mail toggle enabled in iCloud settings	Turn Mail on for iCloud, then reopen Mail
Custom IMAP	Ports, SSL, and SMTP authentication match provider rules	Edit server fields or remove and add with correct values

Reset Network Settings If Mail Won’t Connect Anywhere

If Mail fails on both send and receive, and the web login works, the network path may be the blocker. Resetting network settings can clear bad DNS paths, broken Wi-Fi profiles, and leftover VPN settings.

Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. You’ll need to re-join Wi-Fi networks after this.

Manual Server Checks For Custom IMAP Accounts

If you use “Other” with a custom IMAP setup, the smallest typo can break syncing. If you’re unsure, get the exact incoming and outgoing server names from your provider’s settings page.

Incoming Mail Fields That Matter

• Host name: the IMAP server name (often imap.yourdomain.com).
• Username: often the full email address.
• SSL: should match the provider’s requirement.
• Port: must match the provider’s IMAP port.

Outgoing Mail Fields That Matter

• SMTP host name: often smtp.yourdomain.com.
• Authentication: should be set to use your login.
• SSL and port: must match the provider’s SMTP settings.

If receiving works but sending fails, the outgoing settings are the first place to look.

How To Reset Email On iPhone Without Losing Your Setup

If the account itself is fine and you only want to reset Mail behavior, you can refresh settings around the account without removing it.

• Default account: Settings → Mail → Default Account, then choose your main sender.
• Notifications: Settings → Notifications → Mail, then set alerts per account if needed.
• Signature: Settings → Mail → Signature. Short signatures keep replies readable.
• Swipe actions: Settings → Mail → Swipe Options to match how you sort mail.

These tweaks won’t fix a broken login, yet they’re great when Mail works but feels off.

Do A Clean Test After Any Reset

Testing the right way tells you what fixed the issue and what still needs attention.

1. Send an email to yourself from the iPhone.
2. Confirm it leaves Outbox and appears in Sent.
3. Open webmail or another device to confirm it arrived.
4. Reply from the other side and confirm the iPhone receives it.

If sending works but receiving doesn’t, revisit account sync and fetch settings. If receiving works but sending doesn’t, revisit SMTP and provider security checks.

When The Reset Still Fails

If you removed and re-added the account and Mail still won’t behave, the cause is often outside the phone: a provider outage, a blocked sign-in, or a server change on the provider’s side.

Sign in on the web again, check for security alerts, then try adding the account once more. For custom IMAP, get the provider’s exact server names, ports, and SSL rules and enter them carefully.
