How to Fix Email Not Syncing Across Devices

When your emails aren’t syncing across your phone, tablet, and computer, it can lead to missed messages and frustration. This article explains the most common causes of email sync issues and provides clear, step-by-step instructions to resolve them. You’ll find solutions for both beginners and advanced users to help restore proper email syncing across all devices.

Steps to Fix the Issue

Step 1: Check Your Internet Connection

A stable internet connection is required for email syncing.
  1. Open a website or app to confirm connectivity
  2. Switch between Wi-Fi and mobile data if available

Step 2: Refresh or Manually Sync Your Email

Sometimes emails simply need a manual refresh.
  1. Open your email app and refresh the inbox
  2. Look for a Refresh or Sync option
  3. On mobile devices, pull down on the inbox to force a sync

Step 3: Restart Your Device

Restarting your device can clear temporary software issues that interfere with syncing.
  1. Restart the affected device
  2. Reopen your email app and check for new messages

Step 4: Check Email Sync Settings

Ensure that email syncing is enabled on your device.
  1. Confirm Sync Mail or Background Sync is turned on
  2. Check that sync frequency is not set to Manual or Never

Step 5: Confirm Account Type and Settings (Intermediate)

Your account must be configured correctly to sync across multiple devices.
  1. Ensure your email account uses IMAP, not POP
  2. Confirm your email address and password are correct on all devices

Step 6: Update Your Device and Email App

Outdated software can cause sync problems.
  1. Install the latest operating system updates
  2. Update your email app from the app store

Step 7: Remove and Re-add the Email Account

If the issue continues, re-adding the account can often resolve it.
  1. Back up important emails first
  2. Remove the email account from your device
  3. Add the account again using the correct settings

Step 8: Test Your Email Account via Webmail

Checking webmail helps confirm whether the issue is device-related.
  1. Log in to your email account using a web browser
  2. Check for mailbox storage limits
  3. Look for service outages or security alerts

Advanced Troubleshooting

  • Verify Server Settings: Confirm IMAP/SMTP server names, ports, and encryption settings match your provider’s recommendations
  • Disable Battery or Data Restrictions: Battery optimisation or data-saving modes may block background syncing on mobile devices
  • Clear App Cache: Clearing the email app cache can resolve corrupted sync files (do not clear app data unless you plan to re-add the account)
  • Check Firewall or Antivirus Software: Security software may block email connections on computers or networks
  • Confirm Date and Time Settings: Incorrect system time can cause authentication and sync failures
  • Test on Another Network: Try a different Wi-Fi or mobile network to rule out network-related issues

Before Making Changes

  • Always back up important emails before removing or re-adding accounts
  • Allow time for emails to fully resync, especially for large mailboxes
  • Avoid making repeated changes in a short period, as this may trigger security blocks
  • Only adjust advanced server settings if you are confident or following official provider guidance

Troubleshooting FAQs

Why does email sync on one device but not another?
This is often caused by different sync settings, outdated apps, or POP configuration instead of IMAP.
Will I lose emails if I remove my account?
IMAP accounts store emails on the server and will resync. POP accounts may store emails locally, so back up first.
Can low storage affect email syncing?
Yes. Full device or mailbox storage can prevent new emails from syncing.
Does changing my password affect syncing?
Yes. You must update the new password on all devices to restore syncing.
Why does syncing stop when my device is locked?
Battery optimisation or background restrictions may pause syncing when the device is idle.
