What is the “You may have exceeded the maximum number of connections to this server” error?

When checking your email, you may sometimes see an error message stating “You may have exceeded the maximum number of connections to this server”. Email servers are typically protected with rules that permit only a certain number of concurrent connections from each IP address.

If you try to connect to your email using multiple computers running multiple email clients, you can exceed the maximum number of permitted connections, and the error will be displayed.

Note that this is only a temporary restriction. To resolve the error, simply reduce the number of concurrent connections to the email server by closing you mail applications. Once the number of connections drops below the limit, you will be able to access your email once again.

If you find that you still receive the error, try adjusting your email client settings to reduce the number of cached connections. In Mozilla Thunderbird, you can do this by heading to Tools > Account Settings.

Thunderbird account settings menu

Select your account, then click Server Settings.

Thunderbird account settings

Now click Advanced and find the Maximum number of server connections to cache option. Set this to 3, or lower if you continue to experience issues.
