The stable operation of enterprise email relies on normalized operation and maintenance. Efficient operation and maintenance work can not only reduce the occurrence rate of failures, but also optimize the email user experience and improve team office efficiency. Based on the operation and maintenance scenarios of Tencent Enterprise Email, combined with its product characteristics and technical advantages, this article summarizes core operation and maintenance skills covering four aspects: troubleshooting, performance optimization, security operation and maintenance, and compliance management. It helps enterprise IT administrators quickly solve operation and maintenance problems and achieve refined management of the email system.

Troubleshooting is the core of operation and maintenance work, requiring mastery of common fault location methods and solutions. The common faults of Tencent enterprise email mainly focus on three categories: login abnormalities, email sending and receiving abnormalities, and attachment transmission abnormalities. In terms of login exceptions, if prompted with "domain name unverified", it is necessary to check whether the domain name DNS resolution is correct, with a focus on checking MX and CNAME records. It is recommended to set the TTL to accelerate the effectiveness within 600 seconds; If you forget your administrator account or password, you can reset it through the "Retrieve Password" function by registering a phone number/backup email address; If prompted with 'Account does not exist', please confirm if the email binding process is complete and perform the 'New Enterprise' operation again. In terms of abnormal email sending and receiving, if the email fails to be sent or is returned, it is necessary to check whether the recipient's address is correct, whether the sending quota is exhausted, whether the email content contains sensitive information or has been intercepted by the anti spam system. The "email tracking" function in the background can be used to query the email transmission trajectory and locate the cause of the fault; If you are unable to receive emails, you need to check the blacklist settings to confirm if the recipient has been mistakenly intercepted. At the same time, check if the mailbox capacity is full and promptly clean up redundant emails. In terms of abnormal attachment transmission, if an oversized attachment cannot be sent, it is necessary to confirm whether the attachment size exceeds the 2GB limit. It can be split and sent through a file transfer station; If the attachment cannot be downloaded, you need to check the network environment, clear the browser cache, or switch to the Tencent Enterprise Mail App for download.

Performance optimization can improve the email user experience, with a focus on optimizing storage and transmission efficiency. In terms of storage optimization, Tencent Enterprise Email supports automatic capacity expansion, but still needs to regularly clean up redundant data. Administrators can view the storage usage rate of each account through the background, send cleaning reminders to accounts with over 80% capacity, and focus on cleaning up expired emails and duplicate attachments; At the same time, plan the use of public email and file transfer stations reasonably, regularly archive historical data, and avoid wasting storage resources. In terms of transmission optimization, for enterprise intranet users, it is necessary to ensure that the firewall does not block exmail.qq.com related domain names, and to open IMAP and SMTP related ports (993, 465) to avoid network restrictions affecting email transmission; For international email transmission, the global routing function of Tencent Enterprise Mail can be enabled to automatically select the optimal link, reducing transmission delay and return rate; At the same time, it is recommended that employees use the Foxmail client to implement local email caching and improve email opening speed. In addition, unnecessary functions such as redundant email reminders and unused plugins can be disabled in the background to reduce system resource usage and improve email response speed.

Security operation and maintenance need to establish a normalized mechanism to prevent various security risks. In terms of account security operation and maintenance, it is necessary to regularly check the status of employees' email accounts, and immediately perform the three-step operation of "freeze archive delete" for departing employees. Freezing accounts prohibits login and sending/receiving. According to industry regulations, data should be retained for 30-90 days, and emails should be exported to the designated responsible person's email for deletion to avoid data leakage; At the same time, it is mandatory for all employees to enable secondary verification, regularly remind employees to change passwords, set password complexity rules, and prevent account theft. In terms of anti spam operations, administrators need to regularly check anti spam interception logs, verify intercepted emails, adjust whitelist settings in a timely manner, and optimize anti spam strategies; At the same time, provide security training to employees, popularize methods for identifying phishing emails and malicious attachments, and reduce human security risks. In addition, regularly backup email data, set backup email accounts and backup rules through the backend "email backup" function, automatically backup important emails, and deal with the risk of sudden data loss.

Compliance management needs to be tailored to the business needs of the enterprise, ensuring that email usage complies with relevant regulatory requirements. Administrators need to regularly export system logs, including employee login logs, email sending and receiving logs, administrator operation logs, etc., and archive and retain them for at least 6 months for security audits and accountability tracing; At the same time, according to the characteristics of the enterprise industry, email sending restrictions are set up to limit the sending permissions of core departments (such as finance and research and development) and prevent confidential information leakage. In addition, regularly check whether the email configuration meets compliance requirements, ensure that the email archiving function is enabled normally, the sensitive information detection mechanism operates effectively, connect with the internal audit system of the enterprise, complete compliance checks, and avoid legal risks caused by illegal use of email.

Normalized operation and maintenance also need to rely on the built-in tools of Tencent Enterprise Email to improve operation and maintenance efficiency. Administrators can view real-time data on the operation status, resource usage, and email volume of the email system through the backend "monitoring center", and promptly detect and handle any abnormalities; Utilize the "batch operation" function to batch modify employee permissions, configure security policies, and reduce repetitive operations; At the same time, pay attention to the version updates and feature upgrades of Tencent Enterprise Email, timely enable new security features and operation tools, and continuously optimize the stability and security of the email system.
