4. Suspicious Emails

6. Incorrect Port Numbers
You may receive the Outlook error 0x800ccc0e due to incorrect port numbers. For instance, if you are using an IMAP email account with SSL authentication, you need to use port number 993 rather than 995. In the same way, if you are using a POP3 account with SSL authentication, you should use number 995, not 993.
Refer to the table below for better understanding:
| Account Type | SSL Authentication | Port Number |
| POP3 | Yes | 995 |
| IMAP | Yes | 993 |
| POP3 | No | 110 |
| IMAP | No | 143 |
To verify and/or change the port numbers in Outlook, follow these steps:
- Go to File > Info > Account Settings. Then click Account Settings.
- In the window that opens, select your email account and click the Change button.
- In the new window, click More Settings to open Internal Email Settings window.
- Open the Advanced tab and check the port numbers. If the port numbers are incorrect, change them.
