is a payment method now mandatory for all newly provisioned E5 Instant Sandboxes?
I have an active Visual Studio Professional subscription and can successfully link it to the Microsoft 365 Developer Program. During E5 Instant Sandbox provisioning, the setup requires creation of a Billing Account and entry of a credit card/payment method. The documentation states the E5 Developer subscription is free and billing is used for verification. Is there an alternative verification process for Visual Studio subscribers that does not require a credit card, or is a payment method now mandatory for all newly provisioned E5 Instant Sandboxes?
Microsoft 365 E5 configuration grayed out - TrackingID#2607060030007237
Hello Team, We are currently facing an issue while setting up the Microsoft 365 E5 Sandbox through Microsoft 365 Developer Program. Users are only seeing the option to create an Instant Sandbox, which appears to require billing details. However, the Configurable Sandbox option, which does not involve any cost, is currently grayed out and cannot be selected. We tested this with multiple users within our organization, and the same behavior was observed for both users. This issue was not encountered earlier, as users were previously able to view and select both options — Instant Sandbox and Configurable Sandbox — by default. All impacted users are signing in with organizational email accounts associated with valid Visual Studio Dev Essentials, Professional, or Enterprise subscriptions. We also raised a MS Support case regarding this issue. However, we were informed that this falls outside the scope of a break/fix support case and were advised to post the issue in Microsoft 365 Developer Community forum. This is surprising, as the issue appears to be impacting multiple organizational users and may potentially affect many more members. Requesting your support to review this issue on priority and advise on why the Configurable Sandbox option is disabled, along with the recommended resolution or next steps.

I have trouble with phone number and Microsoft Authentication when login. Where can I find support?
Hello, Currently, I am unable to log in to my email address removed for privacy reasons account. I have the password. I have a backup email address, but when I try to log in, at the authentication step, I don't have the option to receive the OTP code via email. I can only choose to have it sent to my phone number or the Microsoft Authentication app. But when I tried sending it to the phone number, I got the following error: Error Code: 399287 Request Id: 4d13566b-7aa4-4b3f-a03b-0c9416841000 Correlation Id: 019f785d-514f-7eaa-b1a3-ee66302634ae Timestamp: 2026-07-19T03:13:40Z Also, I can't access the Microsoft Authentication app because I've changed devices multiple times. I couldn't find the support form, so I replied to this email. With the admin account password and backup email, how can I log into the admin panel?
