Confluence Office Plug-ins

Hi, I'm facing problems with Confluence Office Plug-ins (Excel, Powerpoint). I'm using FF 20.0.1 as Browser and have also installed WebDav Launcher 1.0.6. Problem is that attached Excel and/or Powerpoint file to with Confluence page is not opened although corresponding Microsoft program starts.

Are parameter settings on Admin level necessary to enable this specific macro? Appreciate your comments. Thanks and best regards Hartmut Stein

Hello Hartmut,

May I ask you if you're using Office 2010 and these Excel/Powerpoint files are being opened "blank"? If so, you can be experiencing this known problem:

Hope this helps, if this is not your problem feel free to comment.

Kind Regards,


Hello Luiz,

sorry attached image was not send. Message box content is as follows:

The following location is going to be opened on your computer:


By the program:

C:\Program Files\Microsoft Office\Office14\EXCEL.EXE

This poses a security risk. If you didn't initiate this action or you don't trust the source of the file, please click Cancel.

Best regards

Hello Hartmut,

Did you get this porblem solved? If yes, what was the solution


There is a security risk installing WebDav Launcher to FF because it can directly open Office documents. Summary of the risks:

  • Office documents can contain macro viruses. Before opening an Office document, make sure that you trust the source of the document.
  • There are known flaws in the Office file formats and Microsoft Office that an attacker can exploit to gain control of your machine. Microsoft has fixed the known exploits in the latest Service Packs for all Microsoft Office versions. But new exploitations may arise at any time. Again, be sure that you trust the source of a document before opening it.

The add-on tries to reduce the risk by supporting the following:

  • Same origin policy— The add-on can only open documents from the same host that initiated the action.
  • Digital signature— The add-on is digitally signed. When you install the add-on please verify that it is signed byBenryan Software Inc.

  • Prompt the user for confirmation— You will always be warned before a file is opened.Please read these warnings carefully before opening a file. The warning tells you the complete URL of the file as well as the complete application path of the application opening the file.

The details are documented here:

Hello Luiz,

thanks a lot for your prompt answer. Will check your proposed IE9 solution but have to involve in this case our external IT service provider as personal access rights don't allow to add trusted sites in IE9.

Actually I'm using FF 20.0.1 as my favorite browser to work with Confluence. Corresponding WebDav Launcher 1.0.6 is also installed to permit MS Office file access.

When trying to open file attachment of a specifc Confluence page I'm getting following message box which I confirm with OK.

Result: Excel is opened but not corresponding file attachment.

Would very much appreciate your comments.

Thanks and best regards

Hartmut Stein
