An unknown error occurred in Microsoft Outlook 2010, error code: 0x80070057

Hello Steve,

There could be several reasons for getting that error, for instance and antivirus program may be preventing Outlook from sending automatic emails, the address book could be corrupted, or outlook might have failed to autocomplete cache.

To resolve it, you will need to do the following:

1. First, you will need to clear the Outlook auto-complete cache. You will do that by typing the following command in Windows Explorer: %APPDATA%MicrosoftOutlook. That will open your Outlook Application Data folder, and then you will look for a file called Outlook.NK2 – select it & delete it.
2. You will need to disable other running programs. You will need to disable the antivirus or firewall program and check if it works.

Hope this helps.

Regards,

Carl

Hi.

To resolve your problem verify that you can connect to internet. If you there is no problem with your internet connection, delete all your e-mails in Outlook and open Accounts menu from Tools options. There re-enter your user data ( username and password ). Also make sure that outgoing and incoming server are same. Close Outlook and open it again. Also download Outlook hotfix script from Microsoft and run it on your computer. You can find it here Outlook hotfix tool.
