@raniaahmed,
I'm not exactly sure what to tell you. The error you are experiencing is definitely due to an issue with the Outlook interop library not being properly registered within the Windows Registry. The only way I've ever been able to address that is to uninstall/reinstall Office. You could search for the DLL and try to manually register it. you should find a copy of it in the Blue Prism Automate folder I believe as long a Blue Prism was installed with the Outlook option enabled. If you don't find it there you'll have to search your system for it.
Once you know where the DLL is located, open a command prompt as Administrator and navigate to the folder where the DLL is located. From there use the following command:
regasm Microsoft.Office.Interop.Outlook.dll
That should add it to the Registry.
Cheers,
