- Wait for a few seconds while the system is repairing Outlook.
- After this is over, restart your PC, and check if you can open Outlook without facing any issues.
If the problem persists even after this, you may re-visit Settings > Apps > Installed apps > Outlook, and this time, reset Outlook.
2. Repair and Reset Microsoft 365
If you have installed Microsoft Office 365 on your computer, you should also try repairing and resetting this app. The steps remain identical to what we have mentioned in the above section. Here’s how –
- Press Windows + I to launch Settings.
- Go to Apps > Installed apps, and scroll down to Microsoft 365 (Office).

3. Configure your SMTP Settings in Outlook
If you are encountering an error code 0x800CCC69 when opening Outlook from Microsoft Office 10, 13, or 16, you should check and modify the SMTP settings. Here’s how to perform this task –
- First of all, open Microsoft Outlook (versions 10, 13, or 16) whichever is installed on your PC.
- Go to File > Account Settings, and select your account.
- When the Change Account window launches, check if the Incoming mail server and Outgoing mail server (SPTP) settings match with your email provider.
