KB2553447 broke concurrent usage of Excel sheets in Word mail merge
-

We use a network based Excel sheet as mail merge source in different Word documents in our Server 2008R2 / Office 2010 environment. Since MS12-046 (KB2553447) only one user at a time can use this source, the second sees the message "External table is not in the expected format".
If I uninstall this update containing the new aceexcl.dll (14.0.6117.5000) and running with the old one (14.0.6015.1000) multiple concurrent users can use the Excel sheet as data source without problems.
Is this a functionality change or rather a bug? It broke our work.
Thank you!
Daniel

Hi Daniel,
Thank you for bringing this to our attention. I have been able to reproduce the issue and have reported it to development. Unfortunately I do not have a timeframe on when this may be address.
I am sorry for the inconvenience this is causing you.
In my testing I did find that this is not an issue if you save your Excel file in the Excel 97-2003 (.xls) file format, nor is it an issue with Office 2007.
Unfortunately my only suggestion would be to save the Excel file in the Excel 97-2003 (.xls) file format but hopefully someone else on this thread will be able to provide additional guidance.
Alternatively you can open a support incident by following the instructions in this article.

Thanks a lot for acknowledging this, Donald!
I'll try the old xls file format and hopefully some day this gets fixed.
