How to Fix 0x800CCC90? [7 Solutions]
Verify Your Login Details
- Start simple. In Outlook, go to File > Account Settings > Manage Profiles. Check your account.
- Retype your username and password carefully. Test it.
If it fails, visit your email provider’s website—Gmail, Yahoo, or similar. Log in there. If that doesn’t work, reset your password. “See? It might be an easy fix,” I say with a nod.
Close Outlook for a While
- Stop using Outlook for a moment. Each action could make things worse.
- Press Ctrl+Alt+Delete, open Task Manager, and look for “Outlook.exe.” End it if it’s running.
Finished? Good. We’re starting fresh.
Check Your Internet
Check your connection. Open a browser and visit a website. If it’s slow, unplug your router. Wait ten seconds, then plug it back in. A weak signal can block Outlook. Let’s ensure that’s not the problem.
Adjust Server Settings
Now, let’s examine the details.
- In Account Settings, select your account and click Change.
- Confirm the incoming server—often “pop.gmail.com”—and port, typically 110 or 995 for secure setups.
Outgoing server is usually “smtp.gmail.com,” port 587. If you are Unsure, Search online for your provider’s settings. Use Test Account Settings. Success? Great. If not, adjust and try again.
Pause Your Antivirus
Your antivirus might interfere. Turn it off briefly—check its menu for a “stop” option. Open Outlook. If it works, allow Outlook in the antivirus settings. “Protection is important, but it needs balance,” I point out.
Repair Your Profile
- If the issue persists, your profile may need fixing. Go to Control Panel > Mail > Email Accounts.
Choose your profile and click Repair. Outlook will attempt to correct itself. Restart the program. “Let’s hope that does it,” I say.
Choose your profile and click Repair. Outlook will attempt to correct itself. Restart the program. “Let’s hope that does it,” I say.
Create a New Profile
The final option: A new profile. In Mail, click Add. Name it something clear, like “NewInbox.” Set up your account again. If it works, remove the old profile. “A fresh start can work wonders,” I encourage.
Does Your Outlook Version Affect This?
“What version do you use?” I ask. Outlook 365 uses cloud features, but this error still occurs. Versions like 2016 or 2019 may need profile repairs more often. Outlook Express, an older program, focuses on POP3 issues. The steps apply to all. You’re equipped to handle it.
