When I double click on an attachment, I’m being asked whether I would like to open or save the file. I would like to open it but I don’t want to answer this question again.
There is an option which says “Always ask before opening this type of file” which I want to turn off but I can’t since it is greyed out.
How can I enable this checkbox and get rid of the prompt when opening my attachment?
Since that option is a system wide change and not limited to the logged on user, you must perform this action with Administrator rights.
As Outlook runs with user-level permissions by default, even when logged on as an administrator, you must explicitly run Outlook as an administrator to change the option.
This option cannot be disabled with standard user privileges.
Note: This setting is per file type. So disabling it for zip-files will not disable it for htm-files. You’ll have to repeat the below process of each file extension you don’t want to be prompted again for.

Another way to start Outlook as an administrator is to right click on its shortcut and select “Run as administrator” from the menu that pops-up.
Unfortunately, this method isn’t very consistent and it depends on your version of Windows and where the shortcut for your application is located whether or not you’ll directly see the option.
Some exceptions are:
Now when you open the attachment you can deselect the option “Always ask before opening this type of file”.
Restart Outlook to have it run safely in user mode again.
