A client I have is having issues around sending email alerts to Contacts & Leads
When you invite a Contact or Lead to a meeting or call and click “Save & Send Invites”
If users are added to the meeting or call the email alert is sent with no problems, but nothing is sent for Contacts & Leads
(The record does not have opt out ticked, all email settings seem to be working for sending alerts to users)
I have tested this and it seems to send an email to a contact added as an invitee. Is it a valid email address?
I cannot be sure with my clients system but I also tested this on our CRM and I received nothing to my Gmail account which is a valid email ?
Will do some more tests linking Contacts
Have you tried testing this on a localhost instance with standard IMAP set up? This issue may be linked to google mail and how it handles mail.
