Dear user, Thank you for reaching out to the Thunderbird Support Forum. I understand that you are currently facing issues connecting to the imap.virginmedia.com server after the scheduled maintenance by Virgin Media. I'll do my best to assist you with this. It appears that the unavailability of email services during the maintenance period might have affected your connection to the server. Here are a few troubleshooting steps you can try: Double-check your account settings: Ensure that the server settings for your Virgin Media email account in Thunderbird are correctly configured. Verify that the incoming server is set to "imap.virginmedia.com" and the port is set to the appropriate value (usually 993 for SSL/TLS encryption). Verify your internet connection: Make sure that you have a stable internet connection. You can try accessing other websites or services to confirm if your connection is working properly. Disable any security software or firewall temporarily: Sometimes, security software or firewalls can interfere with the connection to email servers. Temporarily disabling them and then attempting to connect to the server again might resolve the issue. Clear Thunderbird cache: Clearing the cache in Thunderbird can help refresh the connection settings. To do this, go to "Options" or "Preferences" in Thunderbird, find the "Privacy & Security" or "Advanced" section, and look for the option to clear the cache. Once cleared, restart Thunderbird and try connecting to the server again. If the above steps do not resolve the issue, please provide more details about any error messages or specific problems you encounter while trying to connect to the server. This will help me further assist you in finding a solution.
