Not authorised to send Apple events to System Events. (-1743)

I have a Script that I run as an application (see below) it worked for the last +5 years.

After upgrading to 10.15 from 10.13 I get the following error.

[format]Not authorised to send Apple events to System Events.
Not authorised to send Apple events to System Events. (-1743)[/format]

I looked on the internet but don not seem to be able to find a solution to this problem. Anybody know how to fix this?

tell application "System Events"
	tell application "Microsoft Outlook" to activate
	tell application "Microsoft Outlook"
		if it is running then
			activate
		end if
		tell application "System Events"
			keystroke (ASCII character 107) using control down & command down
		end tell
	end tell
end tell

Try doing a save-as to a new applet.

That did the trick! Thanks.
