I have Windows 10 Pro and Office 2021. I would like to make it so that the Outlook 2021 will show the appointment reminders window on top of all other windows whenever the time for a reminder occurs. According to a Microsoft article , this feature can be enabled by checking a check box under File/Options/Advanced/Reminders; however this is not possible in Outlook 2021, because it says “this feature is only available to Microsoft 365 subscribers on Version 1804 (Build 9226.2114) or higher; it’s not available for Outlook 2021 or older”. However, I don’t want Microsoft 365. Is there another reminders software program (other than Outlook 2021 or Office 365) that I could use that has a feature where the reminders will pop up on top of all other windows whenever the time for a reminder occurs?
