Method 'post' of object 'IOWSPostData' failed

I came across this curious error today. This error pops up when a user (Office 2007) wants to import a spread sheet into a custom list (SharePoint 2007).

Further investigation (Google) revealed that it is a macro inside Office 2007 that is causing the problem. Exactly why, I don't know. But here is my work around, use at your own risk ;-).

Make a backup of the file and edit the file in "C:\Program Files\Microsoft Office\Office12\1033\EXPTOOWS.XLA" (with Excel):

1. Open the file with Excel
2. Press F11
3. Locate the following code:
....
aTarget(iPublishDesc) = Title
lVer = Application.SharePointVersion(URL)
End Sub
....
4. Insert right after: lVer = Application.SharePointVersion(URL)
the following line: lVer = 3
5. Save the file EXPTOOWS.XLA

Make sure you overwrite the file.

That's it! Anyone welcome to leave a comment as to why this happens, or what the consequences would be if you edit the EXPTOOWS.XLA file.
