Troubleshooting common problems with Microsoft Outlook
Updated Thursday February 4th 2021 / Category Web Hosting

Here are some of the common issues with Outlook you might run into, and how to fix them.

Cannot send/receive

There are a few reasons this might be happening, but the first thing you should check is your email software/account settings.

If you’re not sure how you can check the settings for your email account, we have separate guides on how to check the settings in different types of email software.

Most of the settings are the same, such as the Port numbers and SSL/TLS settings. The only difference will usually be the incoming/outgoing server.

For dedicated email hosting services, the incoming/outgoing server will be If you have a cPanel email account, you can usually set (replacing with your own domain) as the incoming/outgoing server. Learn more about obtaining your correct server settings here.

The port numbers are:

  • For secure SSL/TLS connections:
    • The IMAP port is 993
    • The POP port is 995
    • The SMTP Port is 587 or 465
  • For insecure (non-encrypted) connections:
    • The IMAP port is 143
    • The POP port is 110
    • The SMTP Port is 587

Missing folders

Sometimes you might find that certain folders are not appearing or being synced in your email software. We have separate guides for email software where this problem is most common.

Your computer isn’t connecting using modern encryption protocols

Some older operating systems or older versions of operating systems do not support modern encryption (TLS 1.2), which can cause issues connecting to our servers sometimes.

If you’re using Windows XP, Windows Vista or Windows 7 you may have problems connecting because those operating systems either don’t or need to be configured to support modern encryption protocols. Because Windows XP and Windows Vista are very old now there is no solution other than to upgrade to Windows 10. For Windows 7 you can force the use of TLS 1.2, however, it’s still best to upgrade to Windows 10.

Any version of Mac OSX 10.9 (Mavericks) or newer supports modern encryption standards, whereas 10.8 (Mountain Lion) and older do not and you may run into problems. Typically, you can update Mac OSX to a newer version that does support TLS 1.2.

Note, you may also need to update Mac Mail to the latest version as well, to ensure TLS 1.2 is being used.
