Hi @mostapha,
Just as an FYI: my colleague tried to create an account and the verification e-mail ended up in quarantine. She requested release for it and IT came back with the reason as to why it was put in quarantine in the first place:
" We are happy to inform you that the case regarding “Informational-severity alert: User requested to release a quarantined message”, has been resolved with the following resolution:
Based on our troubleshooting, we found that the emails sent from the domain are quarantined due to DMARC failure record which triggered the anti-spam policy to quarantine the email. Hence, this email/emails cannot be released. To stop these emails from getting quarantined, please notify the vendor/ sender IT team to fix their DMARC records."
I hope this helps.
Kind regards,
Marc
