- In order to further confirm if the issue is related to Outlook desktop client, please log in to your web mail to check if everything is ok.
Based on my research, i found that Error 0x800ccc92 is an Outlook error that occurs when sending or receiving emails. It means that the email server rejected your login. It can be caused by incorrect username and password, outdated server settings, oversized Outlook data files, or corrupted PST files. To fix this error, you can try the following steps:
- Verify your username and password for this account in Outlook. Make sure you have entered them correctly and that they match the ones provided by your email service provider.
- If you have recently changed your password, update it in Outlook as well. You can do this by going to File > Account Settings > Account Settings, selecting your email account, and choosing Repair. Then, enter your new password and follow the prompts.
- Considering the impact of some add ins, It is suggested that you try to start outlook in safe mode(win+R>type: outlook /safe) to check whether it works normally.
- Considering that it may be caused by the damage of the profile/data file in the Outlook client, it is suggested that you could try to create a new profile(Control Panel>Mail>Show Profiles>add) and add the account for testing to check if there are some differences.
Hope to help you!
