Does any one have an idea about why emails from the partner users who are using office 365 email address as username and email address for salesforce when they are sending any deal registration approval or new lead creation alert we are not receiving the email alerts. Our IT team investigated it and told us that it is due to email impersonation . We used to receive the emails until Jan 2024 now we are facing this issue.
Does any one have a solution for this.
Thank you.
