Optus Webmail is being retired. The company has confirmed that its legacy email service will close permanently. The shutdown began in stages during 2025 and will not continue into 2026.
Email addresses ending in:
- @optusnet.com.au
- @optus.com.au
will no longer function once deactivation is complete. This is a structured shutdown, not a temporary outage. Users need to move their data before access is removed.
This guide explains what is happening, why the service is closing, what happens to existing accounts, how to back up your emails, and which alternatives you can use moving forward.
Is Optus Webmail Available in 2026
Some accounts remain active in 2026, but availability depends on continued eligibility and login activity. New accounts cannot be created. Accounts that show prolonged inactivity are subject to closure.
Loss of eligibility may also result in removal. Deactivation is permanent.
Access exists today under conditions. Those conditions can change.
Why the Platform Is Being Reduced
Optus operates within telecommunications. Its primary revenue streams include:
- Mobile services
- Broadband connectivity
- Network infrastructure
- Media and entertainment packages
Operating an email service requires constant allocation of resources toward:
- Server infrastructure
- Data storage
- Security enforcement
- Spam management
- Technical support
- Regulatory compliance
Global technology firms dominate the email sector with scale and financial depth. Sustaining a parallel system requires commitment that does not align with Optus’ primary business direction.
Strategic focus has shifted toward network services.
The Risk to Your Connected Accounts
An email address functions as a digital credential. It is linked to:
- Financial institutions
- Government portals
- Utility providers
- Health services
- Subscription platforms
- Online marketplaces
When an account closes:
- Password recovery attempts fail
- Security notifications are undelivered
- Verification processes break
- Service access may be denied
The consequence extends beyond archived correspondence. It affects entry points to critical systems.
How Account Closures Are Executed
The reduction follows a phased structure.
Inactive accounts were evaluated first. Users without recent login activity entered early deactivation phases. Active users receive communication before removal.
Notification allows time to:
- Download stored correspondence
- Preserve attachments
- Export contact data
- Update email details across external services
Required Actions Before Deactivation
Preparation demands discipline.
Archive Your Messages
Connect the account to desktop software such as:
- Outlook
- Apple Mail
- Thunderbird
Use IMAP or POP configuration to download all messages while access remains active. This creates a local archive separate from the server.
Establish a Replacement Address
Viable alternatives include:
- Gmail
- Outlook.com
- Yahoo Mail
Evaluate each option according to:
- Storage capacity
- Security features
- Multi device compatibility
- Long term viability
Open the new account before modifying external systems.
Update Linked Services
Change your registered email address with:
- Banks
- Credit providers
- Government agencies
- Utility companies
- Streaming services
- Retail platforms
Delay increases vulnerability.
Optus Webmail Setup During Service Phase Out
While accounts remain operational, the following settings apply when connecting through email applications.
IMAP Settings
| Setting | Value |
| Incoming Server | mail.optusnet.com.au |
| Port | 993 |
| Security | SSL or TLS |
| Username | Full email address |
| Password | Account password |
IMAP synchronizes messages across devices and maintains consistent access.
POP3 Settings
| Setting | Value |
| Incoming Server | mail.optusnet.com.au |
| Port | 995 |
| Security | SSL or TLS |
| Username | Full email address |
| Password | Account password |
POP3 downloads messages to a single device depending on configuration preferences.
Outgoing SMTP Settings
| Setting | Value |
| Server | mail.optusnet.com.au |
| Port | 465 or 587 |
| Security | SSL or TLS |
| Authentication | Required |
Improper configuration prevents successful sending of messages.
Accuracy in setup prevents avoidable disruption.
The Cost of Inaction
Consider a realistic outcome. Your account is closed due to inactivity or service changes. A financial institution issues a security alert. The notification is sent to a non existent address. You attempt to reset access credentials. The verification link cannot be delivered. Access is blocked.
Email serves as a gateway to nearly every digital system you rely on. Neglecting migration increases exposure to unnecessary complications.

Most email related questions involve account eligibility or activity requirements.
Direct contact is necessary when account access is restricted or when eligibility needs confirmation.
The Current Status of OptusNet Email Accounts
Optus Webmail is not expanding and no new accounts are available. Existing accounts remain functional only while eligibility and activity requirements are satisfied. Closure, once applied, is final.
Preparation preserves access to essential systems. Delay invites disruption.
Act while access remains available.
