Opening attachments issue in Outlook 2010

Hello All,

I have one user who has Outlook 2010 with Hosted Exchange. He can't seem to open Excel attachments properly. I have attached a print screen. When I click on enable editing nothing happens. Nothing at all. We are using Exchange 2010.

Does anyone know how to fix this?

sorry attached.  Print-Screen.pdf
Check they have the latest SP installed.

Also have the user try saving it to their desktop first and opening it

Check to see if cached Exchange Mode is on, if so try turning it off.

Would also have the user try to open it in safe Mode

Start>Run>Outlook.exe /safe

There is a Registry edit that will correct this

1. Quit all Office 2003 and 2007 Office programs that are running.
2. Click Start, click Run, type regedit in the Open box, and then click OK.
3. Locate and then right-click the following registry subkey: HKEY_CURRENT_USER\Software\Microsoft\Office\<version_number>\Common\Internet
4. Point to New, and then click DWORD Value.

if this is only with single user then I believe its not a server side issue. Its something wrong with this particular pc.
So please check the same user on another pc.
Also first save the particular file on pc then try to open and check if the same issue is persist.
Also check the exiting excel file on the particular pc if they are ok.
