Timeslips Outlook Link

SUGGESTED

I am using Timeslips Premium on a Windows 10 Pro system. Outlook is the Office 365 version and has been installed as a 32-bit program. I have entered Timeslips as a permitted application in the Windows Defender Firewall. But, the Enable Outlook Link button remains grayed out. What do I need to do to be able to enable the Outlook link for Timeslips?
