If your rr login is not syncing contacts or messages, you can resolve the issue by updating your account settings and ensuring your rr.com email server details are correct. Start by removing and re-adding your account to refresh the configuration. Make sure IMAP and SMTP settings match the official Roadrunner guidelines. Clear cache and update your email app to avoid sync errors. If the problem continues, log in through the web version of roadrunner email login to check if the issue is device-specific. Also, ensure your internet connection is stable and your account storage is not full.
