When managing an Exchange Online environment, SMTP address management is a crucial aspect. Here are 14 tips to help you efficiently handle SMTP addresses in your organization.

1. Centralized Address Management

Maintaining a centralized system for managing SMTP addresses ensures consistency and reduces the chances of errors. Use the Exchange Admin Center (EAC) or PowerShell to centralize your address management processes.

2. Standardize Address Formats

Standardizing your email address formats makes it easier to manage and remember. For example, you can adopt a consistent naming convention like "firstname.lastname@yourdomain.com".

3. Avoid Duplicate Addresses

Duplicate SMTP addresses can cause confusion and delivery issues. Regularly check for and remove any duplicates in your system.

4. Utilize Aliases Effectively

Aliases can be useful for grouping or role-based email addresses. However, be cautious not to create too many aliases that might complicate address management.

5. Monitor for Unused Addresses

Periodically review and deactivate unused SMTP addresses to keep your address book clean and organized.

6. Implement Address Policies

Address policies in Exchange Online allow you to apply standardized email address formats across your organization. Use them to enforce consistency.

7. Validate Addresses During Creation

When creating new SMTP addresses, ensure they are valid and conform to your organization's standards. This helps prevent future issues with email delivery.

8. Use PowerShell for Bulk Operations

PowerShell scripts are invaluable for bulk address management tasks, such as adding, modifying, or deleting multiple addresses at once.
