At the business I work for we have just migrated our customer auth and account services to Azure B2C however after some complaints from customers and a test with my own personal virginmedia email address I have found that Email verification code emails can take anywhere from 30 minutes to 24 hours to make it to the mailbox - and when they do they wrongfully go into spam. This obviously isn't ideal for our customer journey. I found this odd as emails are sent from Microsofts own domain rather than the companies domain - email@example.com. I have corresponded with a rep at Microsoft who say the issue is on Virgin's end. How do I go about getting us out of any greylists and improve deliverability and speed.
I am part of the software dev team and can provide any extra information if required.
Hi Michael-H thanks a lot for your reply.
I'm going to send a PM to take some details to see if we can get this resolved for you.
Kindly expect the PM from me to arrive shortly and respond directly when you can!
Did you find a solution to this? We did a similar migration to Microsoft Azure AD B2C and have many customers on virginmedia. Their OTP (i.e. a 6 digit verification code) emails from firstname.lastname@example.org are being delayed for multiple hours. Since the OTP codes are only valid for 10 minutes this is stoping virginmedia from accessing their accounts. Any help would be appreciateed.
Hi John, just saw you also replied to my Q on the MSFT forums about this issue when we were experiencing it last year. In the end, I didn't fully follow up on the issue with Virgin when I should have - however as far as I can tell the situation slightly improved with time. I'd be happy to re-open and provide the necessary info to the tech support team to get this resolved for all of us who use B2C.
