The software works great, but when outlook tries to send a reminder email, it has a popup that says "A program is trying to send email...allow?" Can you help to avoid this security feature?

You probably have Windows 2000 ? - If so go to your Windows Explorer, to your C drive, and there should be a folder named Windows or Winnt.

Inside this folder there is a file bypass.vbs, you should right click it, and edit it.

set fso = CreateObject("WScript.Shell")
Wscript.sleep 5000 'control your time 1000=1 second
fso.AppActivate ("Microsoft Outlook") 'calls outlook if it's not the active app

fso.SendKeys "{LEFT}", True
fso.SendKeys " ", True 'there is a space between the brackets

If doesn't work try:

set fso = CreateObject("WScript.Shell")
Wscript.sleep 5000 'control your time 1000=1 second
fso.AppActivate ("icrosoft Outlook") 'calls outlook if it's not the active app

fso.SendKeys "{LEFT}", True
fso.SendKeys " ", True 'there is a space between the brackets

Save the file and try Outlook reminders again.

If this still doesn't solve your problem try this free software: Express ClickYes

I installed the add-in, but I can't find it?
Because the add-ins are integrated into Outlook, and become part of Outlook, they can be found in Outlook. Just go to Tools...Options...(name of add-in). It will be there alongside
If it doesn't go to Other tab > Advanced Options > COM Add-ins and see if it is there, if it isn't click Add go to C:\Program Files find the folder (name of add-in) and select the add-in.
