Well, okay, night-time has little to do with it.

When I try to save aWord document, I get shown the ‘Save As’ dialog.

On it there is the ‘Favorite’ panel (UK English clearly doesn’t apply) and the option of ‘My SharePoint Sites’. Great! Wrong! If I click on the the ‘My Site’ shortcut, it changes the name of my document (‘fixer.docx’ in this case’), and if I double click, it tries to save the document as a file called .docx. The error I then get it ‘Word did not save the document.http://moss:4000/personal/burnsaw/.docx’.

Well, I can see why the error in saving, but huh? What happened to the file name? It wasn’t even the wrong file name of ‘My Site’ – there was no file name at all!

Step two was to repeat, but try using the Word’s ‘Publish > Document Management System’, but got the same result.

Step three was to open up a new document from the library, and try saving back. This highlighted another problem we’ve got – users getting prompted for network credentials when opening a document from SharePoint (this doesn’t happen every time, just the first time each user session). That accepted, it worked and opened a Word document. I typed some text, and did a ‘Save As’. I was shown this dialog:

Hmm. That’s more promising, and it does save to that library correctly. So what do I notice? Well, the address bar is quite different, which is unsurprising as the top one is looking at a folder of local shortcuts. But the URL it’s pointing to is correct.

I don’t know what is going on here, but it has that irritating WebDav feel to it.
