Are you facing the frustrating issue where Apple Mail cannot connect to the server, leaving you wondering why your emails aren’t syncing? Apple Mail is Apple’s built-in email client, designed to seamlessly sync across Mac, iPhone, and iPad. While most users enjoy smooth performance, some encounter problems that prevent Apple Mail from connecting to the server.
When Apple Mail loses connection, it can disrupt your email workflow. This may delay sending or receiving messages, block access to past emails and contacts, and, even worse, risk potential data loss if the issue isn’t addressed promptly.
If you are experiencing this “unable to connect to server” problem, don’t worry. In the following sections, we’ll break down the common reasons behind this error and provide practical solutions to get Apple Mail reconnected and working normally again.

How to Tell if Apple Mail Can’t Connect to the Server
If you’ve noticed that you can’t send emails in Apple Mail, or haven’t received new messages for a few days, it could be a sign of server connection issues. Common symptoms include error messages like “Unable to connect to server” or a spinning wheel next to your account name. These indicate that Apple Mail is unable to establish a connection with the server hosting your email account.
When this happens, it can affect your email usage in several ways:
1. Unable to Send or Receive Emails: The most obvious sign of server connectivity issues is that emails cannot be sent or received through Apple Mail.
2. Emails Stuck in the Outbox: Without a connection to the server, emails you try to send remain in the Outbox. Likewise, new emails won’t arrive until the connection is restored, potentially causing delays or missed communications.
3. Email History Fails to Load: If Apple Mail loses access to the server, it may only display recent messages while failing to load older emails or your full contact list.
4. Risk of Data Loss: Extended connection problems can sometimes result in missing emails or unsynchronized data, especially if messages haven’t been backed up.
Common Reasons Why Apple Mail Can’t Connect to the Server
Several factors can prevent Apple Mail from establishing a reliable connection with your email server:
Incorrect IMAP or POP Settings: Apple Mail uses IMAP or POP protocols to communicate with email servers. If these settings are incorrect, the Mail app cannot access your messages, causing connection failures.
Security Protocol Mismatch: Most email servers require encryption through SSL/TLS. If your Apple Mail settings don’t match the server’s encryption requirements, the connection may be rejected.
Software Conflicts: Other software on your Mac, like additional email clients, utilities, or security programs, can interfere with Apple Mail and prevent it from syncing properly.
Firewall Restrictions: Mac firewalls monitor and control incoming and outgoing network traffic. If your firewall settings are too strict, they may block Apple Mail from reaching the server.
Server Maintenance: Sometimes email servers undergo scheduled maintenance, temporarily making them unavailable. During this time, Apple Mail may fail to connect, and there’s little you can do except wait for the maintenance to finish.
Internet Connectivity Problems: A stable internet connection is essential for Apple Mail. Unstable Wi-Fi, network congestion, or router issues can disrupt communication with the server, preventing emails from being sent or received in real time.
How to Fix Apple Mail Unable to Connect to Server
If Apple Mail is struggling to connect to the server, there are several steps you can take to troubleshoot and resolve the problem. Below is a list of practical solutions that often fix this issue:
1. Restart the Mail App: Sometimes, simply restarting Apple Mail can resolve minor syncing issues. Close the app completely, then reopen it. To refresh your inbox, go to the Mailbox menu at the top of the screen and select “Get All New Mail”, or press Command + Shift + N. This prompts Mail to check for new messages and update your inbox.
2. Update Your Email Account Password: If you recently changed your email account password, Apple Mail may no longer sync properly until the new password is updated. Here’s how to do it:
- Open Mail and go to Settings.
- Click Accounts and select the account that isn’t working.
- Enter the new password for the incoming mail server.
- For the outgoing mail server (SMTP), navigate to Settings > Mail > Accounts > Outgoing Mail Server (SMTP) > Advanced, then enter the updated password.
After updating, give Mail a few minutes to resync with your email account.
3. Remove and Reconnect the Email Account: If updating the password doesn’t help, removing and re-adding the email account can refresh the connection and resolve underlying issues. To do this, simply remove the problematic account from Apple Mail and set it up again from scratch. Once reconnected, check if emails are sent and received properly.
4. Reset Firewall and Security Settings: In some cases, Mac firewalls or security software can block Apple Mail from connecting to the server. Temporarily disabling the firewall or adjusting security settings may allow Mail to sync again. Make sure the app has permission to access the internet, then re-enable your firewall while keeping the necessary ports open:
- Port 143 for IMAP
- Port 110 for POP
Opening these ports often resolves issues with Apple Mail failing to refresh the inbox.
Consider Apple Mail Alternatives
If you manage multiple email accounts and keep encountering connection problems, it might be worth exploring alternative email clients for Mac, before switching apps, always back up your Apple Mail mailboxes to avoid data loss.
- Tools like CubexSoft Apple Mail Converter allow exporting Apple Mail data to multiple formats.
- For MBOX files, MBOX Converter for Mac can safely convert and preserve your email data.
By following these steps, you can usually restore Apple Mail’s connection to the server and prevent future syncing problems.
Conclusion
Apple Mail unable to connect to the server can disrupt communication and delay important emails. Most connection issues are caused by misconfigured settings, network problems, or temporary server downtime. By following the steps above, restarting Mail, updating passwords, checking server settings, and troubleshooting firewall or connectivity issues, you can usually restore normal functionality.
Regularly backing up your mailboxes and ensuring correct account configurations can prevent future problems. If issues persist, consider alternative email clients while keeping your data safe with reliable backup tools. With these solutions, you can get Apple Mail syncing again and maintain uninterrupted email communication.
