Having issues adding an Optusnet email account to Outlook 365 App on Windows 10,11 or Mac?.
The Optus online guides are hopelessly outdated, all referring to old outlook versions.
The Optus technical support people are CLUELESS and have no idea about this issue.
Try the following 2 solutions
Solution 1 – Use an App Specific Password
What Optus does not tell you ANYWHERE on it’s site, is that you now need to use an “APP SPECIFIC PASSWORD” in place of your usual Optus login password in order to add your OptusNet address to Outlook on either Windows or Mac
Trying to add your Optus password, throws an error:

Step 1 – Generate App specific password by logging into optus Webmail
Login to Optus Webmail on a Browser (procedure is identical for Telstra and Optus)
Use the password that you always use to login to your Optus webmail or optus account.
This is the password … THAT DOES NOT WORK ON the OUTLOOK App

- Click on the nine-dots in the top left menu and select “Settings”
- Click on “Accounts”

- Look for “App Specific Passwords” and click “Generate Password” giving it a name such as “Outlook Password”
- Make note or the very unfriendly computer generated password. We suggest using a copy and paste technique as the password will not have to be re-entered too often.

- If you have any old Optus accounts in Outlook App (Program), remove them first.
- Create new account in Outlook App (Program)
- When prompted for a Password in Outlook, use the “App specific password” generated from Optus Webmail (see above)
Once done click “Next” and if the passwords was added correctly, the account will be added to your Outlook App (Program)
Close Outlook and reopen Outlook for the new account to appear
Solution 2 – Check the following Windows settings

Conclusion
Now, think about transitioning from Optusnet to a free outlook.com account as OptusNet emails is not going to be around much longer.
