When you are assigning an email address to be synced to a record/s, this gets saved in the Auto-Association database. You can look up the email address and see what records it is associated with or you can also turn off the email address sync if need be.
This will be available for Enterprise users only that are using Autopilot 2.0.
Step 1: Go to Menu on the ExtendSync panel then select Settings.
Step 2: Go to Email Autopilot Associations and enter the email address you want to check. Click on the matching email, this will allow you to do two things.
See the list of NetSuite records the email address is associated to
Remove the Autopilot association completely for the email address.
Hover on the trash icon of the records where you want to turn off the Autopilot.
Emails from that email address will NO LONGER automatically be associated with those record(s).
💡 Notes
To get the list of email addresses with the auto association, you can enter @companyname, .com, .org , .edu or any part of the email
as ExtendSync is doing a wildcard search.
