Internet Explorer 10: No "Open" option when clicking on an attachment

the "Speichern" (means "Save" in english) will save in temp folder to then open the file with default viewer.

Yes, "speichern" means save.  But I want the option "Open" directly without saving the document.

Hi angelIII hope you are fine?

@whenz
Do you have Office 2010 or 2013? And you need this only for MS Office files or all files?

Hi hepeleonie

We use Office 2010, if I need to allow the option "Open" for all files (also pdf etc.).

thx

Office and Windows are up-to-date?
And you have Windows 7?

Yes, Office and Windows are up to date and we use Windows 7 with IE10

Download Microsoft Baseline Security Analyzer on a Test Client and run it. Do you miss some updates?

this has nothing to do with windows updates.  I figured out that the attachements from the intranet don't have the option to "open" files directly.  When I surf on other websites I can open files like pdf's directly.

There was a fix for this problem. One case was opened and the solution from MS was to install all updates.

Thank you for the advise.  I confirm that all Microsoft Updates are installed.
