I am also looking for a similar feature. End Users want to add emails related to case as an attachment for reference. However, the system gives a "Cannot Open File: C:\Users\XXX\AppData\Local\Microsoft\Windows\Temporary Internet Files\Conte... The file may not exist, you may not have permission to open it, or it may be open in another program."
Implies, that the file is not added to the case at all!! Is there any solution for this?
Have a dual screen platform with one having outlook and other having Pega application running (you can have both the windows open simultaneously on the same screen)
Drag an email from outlook inbox and place it in the drag and drop section of attachments
Pega will show that the attachment has been added
Try opening the attachment
System gives the error i mentioned above.
Drag & drop ActiveX control in Pega 7.1.8 has been finalised to be used only for IE 9. So, if you are on any other version of IE (or any other browser), drag & drop ActiveX is not loaded but an HTML5 control is used which does not support drag/drop directly from outlook.
I think versions lesser than IE11 will display Activex controls. In IE11, you might need to enable compatibility settings to enable drag n drop from outlook. It looks like Pega is trying to get away from ActiveX Controls in the newer versions.
