SharePoint 2010 Help doesn’t work after migration

I had to migrate a MOSS 2007 farm to SharePoint 2010. – After migration the SharePoint Help did not work. (It’s the button upper right on a SharePoint site.)

A popup window appeared and I got an empty site with the message “Help not available” (or something like that: It was a german site so the error message was german…)

I tried a new created web application with a Team Site collection. There the help does work as expected.

Then I had a look into the Windows Event Log. There I found a related error. The web application pool account of my migrated web application did not has access to the Admin Content database. But the application pool account of the new created web application was enabled to access this database. – After adding the application pool account of my migrated web application as “db_owner” the help was shown as expected.

(I have no screenshots of that. Sorry. But I think, that can be reproduced easily by removing the application pool account from the Admin Content database.)

Missing “View in Browser” and “Edit in Browser” in the context menu of Excel files in a SharePoint 2010 document library…

You have installed the Office Web Apps on your SharePoint 2010 server. Now you are missing the menu entries “View in Browser” and “Edit in Browser”.

You create a new Excel file in Excel 2007 or 2010, upload it and… there are the menu entries… maybe…

This was the situation of my customer yesterday. He tried to open documents in the Office Web Apps after migration from MOSS to SharePoint 2010. Everything seems to work: Word Web App, PowerPoint Web App, OneNote Web App…

I created a new site collection and uploaded a Excel file (XLSX). – The menu entries appeared.

Then I uploaded a document I’ve downloaded before from the migrated site collection. The menu entries were gone… – THEN I REALIZED: To new document was in OpenXML format (Excel 2007, Excel 2010), the migrated documents in native Excel format of Excel 97…2003. Thats the problem: Only OpenXML Excel files can be viewed an edited in the browser!!! – Thats diffrent from Word Web App and PowerPoint Web App.

I’m looking around on the Microsoft web site, but till now I’ve not found an official comment on that. But this seems to be “behavior by design”… Don’t waste as much time as I’ve wasted with that!
