The error message itself being worded pretty straightforwardly means there is no need to search elsewhere to understand the root cause of the issue. The Error 0x800ccc0f occurs as a result of Outlook being unable to connect to MailEnable servers. There can be a lot of scenarios that has led to this situation such as:
- An antivirus in your system is blocking MS Outlook’s access to server.
- The windows Firewall might be blocking Outlook access to server.
- Network connectivity issues.
- Conflict between windows products.
- Outlook data files may be inaccessible or corrupt.
Let’s tackle each of these scenarios one by one:
Antivirus blocking access: This occurs if you have email protection features of your antivirus enabled (most have it enabled by default). The trouble with leaving it enabled is that your anti-virus will insist on checking every single mail received from the POP server, which can create conflicts with Outlook. Turning off email protection feature will resolve any issue that might have arisen due to it, however, in worst case scenario you might have to uninstall your antivirus suite as a whole and look for alternatives.
Windows Firewall: To make sure the windows firewall isn’t blocking access to MS Outlook try disabling it once. The steps to disable windows firewall are as follows:
- Open control panel from the start menu.
- Select Network configurations from the control panel.
- Right click the connection that you are currently using.
- Go to Securities tab and switch off Windows firewall.
After this we have to manually configure incoming POP server name (pop.gn.apc.org) and the outgoing SMTP server name (smtp.gn.apc.org) in Outlook. To accomplish this:
- From Outlook Tools menu choose Accounts.
- Select View or change existing email accounts.
- Select ADD from the dialogue box that appears and choose POP3.
- Fill in the correct POP3 mail server information and verify them before finishing.
Network connectivity issues: Troubleshoot and resolve any network connectivity issues that could be hindering connection attempts by MS Outlook. Restart the routers and check connectivity to other servers in same switch if necessary.
Conflict between windows products: This is an issue acknowledged by Microsoft themselves, conflicts between some of their services can also result in Error 0x800ccc0f. So if you are using an older version of windows make sure to upgrade it to the latest service pack in order fix this issue.
Outlook data files: If none of the above solves the issue, then it could be a case of Outlook data file corruption, in which case you can try to repair and recover the data files using Inbox repair utility – scanpst.exe and scanost.exe for PST and OST files respectively.
