how to syn outlook with borg calendar for email notification


New Email
I'm trying to sync Borg calendar with email so I can get email notifications about calendar events. I've tried the following, but it won't send emails. Borg Email paramenters and my entries are:
Enable email which I checked
smtp server:
smtp port: I've tried both 25 and 587
smtp user: entered my email address
smtp password: entered my password
to email address: entered my email address
from email address: tried both leaving it blank and entering my email address
reminder email time: I entered 7:00
Enable TLS which I checked
I'm not very knowledgeable about email parameters so I would appreciate any help. Or any suggestions for another free desktop calendar that will easily sync with to send notifications. Thank you.
