Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
I'm facing the same issue since Apr, 2023. Even the customer support doesn't have any fix for this strange issue. I'm using the same phone across all other Microsoft services, everything is working except this thing.
There's no fraudulent or spam activities in my phone number, but still then Microsoft 365 E5 Developer throws an error Your phone didn't pass security checks with an error code 40315.
We just can't get more phone number for accessing your services, do provide genuine fix for an issue. I've been raising this issue since Apr, 2023.
Hope to hear from you soon.
