Email Administrators must address any Microsoft Exchange Server-related issues to maintain email communications. There are not many more nightmare-ish scenes than being a System Administrator in charge of the mail services and the mail server goes down — just take my word for it!

Here is a list of a few things that will help reduce the occurrences of mail server complications.

1. Recognize Problems. Understand specific Exchange Server failures such as email delivery failure, database corruption or connectivity issues.
2. Log into the Exchange Admin Console. Check on the status of all of your Exchange services. You may need to restart any services that have been temporarily suspended.
3. Review Events Viewer. To stay abreast of Exchange related warnings and errors, regularly monitor Event Viewer logs. By identifying error codes or messages you can easily pinpoint specific problems.
4. Utilize Exchange Problem Solvers. For troubleshooting Exchange problems and to identify inconsistencies or configuration issues, Exchange Best Practices Analyzer provides an invaluable resource.
5. Review Your Mail Flow. Utilizing tracking tools, identify any bottlenecks or issues in message routing.
6. Database Integrity Checks and Repair. Use Eseutil or Exchange Management Shell cmdlets to run database integrity checks (eseutil /mh or New-MailboxRepairRequest), then repair if necessary.
7. Update Exchange Server. To keep Exchange Server running smoothly and effectively, make sure its most recent service packs or cumulative updates have been installed.
8. Increase Available Disk Space. When operating Exchange server drives that host databases and audit logs, make sure there is sufficient disk space available; low disk spaces can disrupt mail flow.
