Check Your Email Account Type
- IMAP: Keeps messages synced between your device and the server (recommended).
- POP: Downloads messages to your device only (not recommended if you want real sync).
- Tip: Most modern accounts (Gmail, Outlook, iCloud, etc.) use IMAP by default.
Add or Review Your Email Account in iOS Mail
To check or set up your account:
- Open Settings on your iPhone or iPad.
- Scroll down and tap Mail.
- Tap Accounts.
- Select your email account, or tap Add Account to set up a new one.
Ensure IMAP Is Being Used
If you’re adding a new account, select IMAP if prompted. For most providers (Gmail, Outlook, Yahoo, etc.), this is handled automatically.
Enable Push/Fetch for Your Account
- In Settings > Mail > Accounts, tap Fetch New Data.
- Turn on Push (if supported by your provider) for real-time sync.
- If Push isn’t available, set Fetch to a schedule (e.g., every 15 minutes).
- Make sure the appropriate fetch schedule is selected for each account.
Confirm Server Settings
If mail isn’t syncing, check these:
- Go to Settings > Mail > Accounts > [Your Account] > Account > Advanced.
- Confirm the IMAP Path Prefix (usually “INBOX”), server ports, and SSL settings match those provided by your email service.
Common IMAP settings:
- Incoming server: imap.yourprovider.com, port 993, SSL enabled
- Outgoing server: smtp.yourprovider.com, port 465 or 587, SSL enabled
Test Sync
- Open the Mail app and try sending/receiving messages.
- Make a change on another device or webmail—confirm that the change appears in iOS Mail.
Troubleshooting Tips
- Delete and re-add your account if sync fails.
- Ensure your internet connection is active.
- Update your device to the latest iOS version.
- Contact your email provider for correct server settings if unsure.
