I just setup my 1 user office 365 starter, but nothing is working. I can login from webmail. When i press Mail icon, an error message appear like
The mailbox isn't available. This may have occurred because the license for the mailbox has expired. To find out how to gain access to this mailbox again, contact the person who manages your email account.
Why there is license invalid?
Welcome to the community!
Were you able to access the account yet? You mentioned just recently setting up the plan at the time of your post, so it might have been a setup delay issue. Sometimes a new account may require full hour to complete setup on the back end.
If you're still encountering the issue to this point, please reach out to our live support so they can help investigate and correct this.
