@Anurag1990 is correct. I was extremely happy to see this feature rolled out, however it’s not functioning properly. The main selling point behind having multiple domains associated with an account is to automatically associate any new contacts with any of those multiple domains under the same account. Otherwise the system STILL makes duplicate accounts and forces admins to go in and merge the real account with the duplicate account (or manually de-associate and re-associate contacts with the right accounts if you have the Salesforce integration
).
I was so excited to see this functionality rolled out and was raving about it to anyone who was listening - so disappointed that it’s not working appropriately. @ethankopit Is a fix in the works?
