Web-to-lead lead assignment notification email alerts have suddenly stopped sending to outlook inbox. I should receive all workflow email alerts as the person cc'd with the lead owner as the main person in the email.
What I have tried
checked SF email log and they are showing as sent however I am not seeing them in my inbox.
checked Deliverability settings and they are correct to show 'all emails'
sent test from email template and is working fine
did IP address checks and have received all that were sent
Any help would be much appreciated
