It can be frustrating when you open an important email on your iPhone, iPad, or Mac, only to see the error message: “This message has not been downloaded from the server.” This issue can interrupt your workflow and make vital communication inaccessible. The good news is that, in most cases, it is fixable with a few logical steps. This guide will walk you through the most common causes of this error and provide reliable, practical solutions.
Understanding the Error
This error typically appears in Apple Mail or third-party email apps that use the default Mail framework. It means the email client attempted to retrieve the message body from the server but failed to do so. Reasons vary from connectivity problems to corrupted data.

Common Causes
Before diving into solutions, it’s important to understand the root causes. Here are the most prevalent ones:
- Network Issues: Poor or unstable internet connectivity may prevent your device from accessing the server.
- Mail App Glitches: Temporary app or operating system glitches can lead to incomplete email downloads.
- Email Server Settings: Incorrect IMAP/SMTP configurations interfere with message retrieval.
- Corrupted Email Data: Emails or attachments may be partially downloaded and become unusable.
- Outdated Software: Older versions of iOS or Mail may not function optimally with your server’s protocols.
How to Fix “This Message Has Not Been Downloaded from the Server”
To resolve this issue, follow the steps below systematically until the problem is fixed.
1. Check Your Internet Connection
The most basic reason is often overlooked. Make sure your device is connected to a stable Wi-Fi or mobile data network. Try browsing the internet or streaming a video to confirm connectivity.
2. Force Quit and Restart the Mail App
Sometimes, simply restarting the Mail app can solve temporary glitches:
- Swipe up from the bottom of your screen (or double-click the Home button).
- Find the Mail app and swipe it off the screen to close it.
- Reopen the app and try reloading the email.
3. Delete the Affected Email Account and Re-add It
This is a more aggressive fix but often solves issues tied to account syncing:
- Go to Settings > Mail > Accounts.
- Select the problematic account and tap Delete Account.
- Restart your device.
- Navigate back to the Accounts section and add the email account again.
Make sure you have your email credentials handy before doing this.
4. Turn Off SSL for the Email Account (Advanced)
In rare cases, Secure Socket Layer (SSL) encryption may cause communication problems between the Mail app and the server:
- Head to Settings > Mail > Accounts.
- Tap on the email account, then Advanced Settings.
- Toggle off Use SSL.
- Exit settings and try reloading your email.
Note: Disabling SSL can reduce your email security, so proceed with caution and consult with your email provider.
5. Reset Network Settings
Corrupted network settings can hinder mail retrieval. To reset them:
- Go to Settings > General > Transfer or Reset iPhone > Reset.
- Select Reset Network Settings.
This action removes saved Wi-Fi passwords and VPN settings, so be prepared to re-enter them afterward.

6. Update iOS or iPadOS
Old software can be incompatible with newer email protocols. To update your device:
- Go to Settings > General > Software Update.
- If an update is available, download and install it.
7. Try Using Webmail
If the message still doesn’t download in your Mail app, log in via a browser. Go to your email provider’s website and check if the message can be accessed there. This confirms whether it’s a local app issue or something on the server’s end.
Final Thoughts
The “This message has not been downloaded from the server” error is undoubtedly inconvenient but rarely a dead-end. With the above methods, there’s a high likelihood of restoring full access to your emails quickly and efficiently.
If none of these steps resolve the error, consider contacting your email provider or Apple Support for more in-depth analysis. Staying proactive with software updates, backup practices, and regular email account maintenance can also prevent similar interruptions in the future.
