Solved Outlook gets error after system recovery.

July 13, 2016 at 07:09:58
Specs: Windows 7
I am getting ECF errors when I open Outlook and "operation failed" when I try to Send/Receive e-mail in Outlook. I have tried Detect and Repair, scanpst and creating new mail profiles. I also renamed the extend.dat file (the file is present in two different user profiles) and removed the add-ins.
Here's the story: I ran HP system recovery on a PC running Windows XP Media Edition after I was unable to recover from a registry cleaning utility. (I know - always back up the registry first - lesson learned). The system recovery did not format the C portion and lay down a fresh install like I expected it to. It did restore the OS (applied 101 updates) and the original software that came with the PC. I uninstalled the trial version of Office 2003 that came with the PC and installed a licensed copy of Office 2007.
What should I do to repair this installation?

mmm There are times when Outlook is a real PIA...

A google type trawl for the error does bring up quite a tot...

Se if these are any help:

I'm presuming you're using Outlook 2003...?

The search term/string I used in Google was:

ecf error when i open outlook 2003

Perhaps repeat my trawl using the same string (if the above don't resolve it) and/or outlook 2007; and even just plain outlook?

If you get any of these error messages when you start Microsoft Outlook:

Error in configuration file "C:\Program Files\Microsoft Office 97\Office\Addins\<filename>.ecf"

The extension configuration file "C:\Program Files\Microsoft Office 97\Office\Addins\<filename>.ecf" could not be installed. There is an error in the syntax or format of the file.

Unable to load <filename>.dll. You may be out of memory, out of system resources, or missing a .dll file

**Replace the Damaged Extensions**

To replace the damaged extensions, follow these steps:
1.Quit Outlook.
2.Insert your original Setup CD into the drive. If you installed from the Web this will not be necessary.
3.In the \Program Files\Microsoft Office\Office\Addins folder on your computer, rename the problem .ecf files referenced in the error message.
4.Click Start, point to Settings and click Control Panel.
5.Click to open the Add/Remove Programs icon.
6.Click to select Microsoft Office 2000, and then click Add/Remove.
7.When prompted, click "Repair Office". This will replace the .ecf files that were renamed earlier.
8.Restart Outlook.

✔ Best Answer
Was it this article that led you to rename extend.dat? Did you do the registry updates, too?
When uninstalling 2003 may have been better if you used windows installer cleanup utility as an uninstall of 2003 still leave behind registry entries.
Uninstall Office again using the cleanup utility, and reinstall.
But first try to restore pst file using Recovery Toolbox for Outlook and keep it.
