Outlook 2010 error upon opening

We have a client running windows XP with Outlook 2010. Recently the security update KB4011273 for outlook prevented the user from opening outlook and received the error "CompareStringOrdinal not found in dynamic link library KERNEL32.dll and the error displays OLMAPI32.dll."

The update has been disabled from reinstalling. The error message is back.

I renamed OLMAPI32.dll to OLMARI23.dll.old and then restored the program and rebooted.  And sure enough I still have the same error message.

Unfortunately the OS and many programs are extremely out of date, so it makes it difficult to do a whole lot of troubleshooting. Even trying to connect to the windows update page isn't the easiest.

Any help would be appreciated.

I do not know what you use (Kerio, Exchange)... but first - reinstal Kerio or whatever you use.

Sorry, Should have mentioned that. They use exchange. Everything has been reinstalled
Have you really got rid of the security update for Outlook 2010 - KB4011273?

As a side note, I would add that you should strongly encourage your client to upgrade. Windows XP is no longer supported by Microsoft and really is not secure any more, especially for getting online. I would not trust it.

I will try uninstalling KB4011711 as well and report back

Uninstalling KB4011711 seems to have worked. However, I obviously need to prevent the update from being applied again. Now when reaching the webpage for updates, I now get an error 0x80072F19... I have searched and turned up very little about it.

I have temporarily told windows update on the PC to just download and choose to install.
To do this use Microsoft Hide Updates Tool.
