Hi Jon,

One of the major causes for Mac outlook error code 3259 is for the wrong implementation or incorrect configuration of POP3 settings. This error don’t allow emails to flow at the receiving end but that doesn’t stop users from sending emails to other accounts.

In order to rectify MAC Outlook 2011 error code 325, you need to follow these following steps:

• Before getting into the technicalities, first check the web connectivity by signing in your MAC Outlook user account.
• Now reconfigure the POP3 correctly. To configure your POP account follow the below mentioned steps:

1. Launch your MAC outlook application
2. Now select your Microsoft Outlook account by clicking on the tools button
3. Mention Pop3.live.com in your Incoming Server text box
4. Keep your Port number to 995
5. After configuring Incoming server, specify outgoing server by mentioning smtp.live.com in your Outgoing server text box
6. Keep your port number to 587
7. Now, click the more options button
8. In the Authentication tab select Use Incoming Server Info.
9. Now click on close and exit the application
10. And finally, click send and receive. 

I hope this helps.

Regards,
Lokesh
