Firebase authentication emails are blocked by Office 365
Hi arnotixe,
I'll send you a private message with a test email address in a dev O365 tenant. So you can send there a message and I'll be able to trace it and see if something is blocking it.
I tried the https://sender.office.com/ to delist it, but it said it sent a confirmation email to the email that I was trying to delist. This is an email provided by Firebase with literally the "noreply" at the beginning. Obviously, I can't access it. Any other suggestions? It seems like you are basically just saying, nothing we can do, we have big dumb spam filters that suck at precision and there is nothing we are going to do about it.
This is kinda bullshit to be honest. I get that some people use these services to spam, but with the tech available today to sort out who is using it for spam and who is using it for legitimate purposes, this is a big FAIL for Microsoft. Probably still using regression for spam filters.
Ironically, I was just looking into whether I should use Outlook or Gmail for my company's emails. I do not have problems with blocking from Gmail from any other service, whether it is a Google service or otherwise. This sealed the deal to use Gmail, thanks for making the decision easier!
kbourne650yeah, I'm tempted to actually buy one of those Whitelisting services Microsoft themselves offer… It is a stretch at about $1500 a year though o_O
As an alternative I'm currently adding SMS login, bypassing the problem to an extentSSO is another option, but setting it up is pretty heavy, and if you want Auth0 to take the app integration for you, a quote there was $30 000 a year (--PER MICROSOFT TENANT!!). As I have about 70 Microsoft customers, that is, well, out of the question.
I've also tried registering at https://sendersupport.olc.protection.outlook.com/snds/pref.aspx but the confirmation mail never reaches me (and no, I don't block their emails, and the email address I choose for notification IS working). Also I don't know if that page has anything to do with this issue.
Only thing that makes me feel a little bad about paying up for "email deliverability to Microsoft" is that it is basically a kind of hostage situation. We need to send mail there, but have to pay $1500 a year for them to take it? Hmmmmmmmmm
If you find any better pointers, PLEASE let me know 😄 I'll do the same
