This article will guide you the different causes for the error 'your IMAP server wants to alert you to the following'.
IMAP #Error code #0x800cccdd appears alongside the message "Your IMAP server closed the connection", which signifies that the "Send/Receive" feature—a setting that retrieves your #Outlook mail whenever connected to the Internet in order to keep your mail synced—has failed.
The error message "Your account temporarily blocked for #IMAP use. This may be happen if you exceed the maximum number of simultaneous IMAP connections allowed. Kindly try after some time" occurs when the mail client or different mail clients are trying to establish too many connections to IMAP server.
A server connection timeout means that a server is taking too long to reply to a data request made from another device. Timeouts are not a reply message: they show up when there isn't a reply and a server request is not fulfilled in a predetermined length of time.
To fix the mail server is not responding:
1. Check your internet connection.
2. Check your #SMTP server details.
3. Verify all usernames and passwords.
4. Check your SMTP server connection.
5. Change your SMTP port.
6. Control your #antivirus or #firewall settings.
