I did not receive the email containing the Microsoft key.

If you did not receive the email containing the Microsoft key, there could be several reasons for this:

1. Email Blocked or Filtered: Check your inbox settings to see if the email was blocked or filtered into your junk mail folder.
2. Incorrect Contact Information: Ensure that the email address associated with your Microsoft account is correct and configured to receive emails.
3. Email Delivery Delays: Sometimes, there can be delays in email delivery, so it might be worth waiting a little longer.
4. Service Activation Email Already Sent: If the service activation was already completed following a previous order, no additional emails will be sent.
5. Future Usage Date: If the order usage date is in the future, the activation email might not be sent until closer to that date.

If you still do not receive the email after checking these factors, consider reaching out to Microsoft support for further assistance.
