I tried to send an email to a friend yesterday from my iPad and it said it could not send. I now don’t seem to be able to send or receive emails. I contacted Apple who looked into the problem and they said the issue wasn’t with the iPad but Microsoft had blocked my account with Error Code 5.7.520 which is something to do with spam detection. How do l recover my account and start sending and receiving my emails. Thanks Richard Cooper

2026-06-20T13:37:44.8+00:00 Hi,
Actual Human here but I am afraid due to forum limitations, I cannot call you :(
- Is it an Outlook.com or an Exchange account?
- How many emails you send on an average, per day?
I’m eager to hear back and work together to find a solution.

2026-06-20T16:38:35.6366667+00:00 It is an outlook account. Send a few emails per day. Apple tell me Microsoft have blocked my account. Error Code 5.7.520. Please restore my email account.

2026-06-21T16:41:12.1766667+00:00 Thanks for your response. I have filled in the form with the correct email address and IP address (from my iPad) and submitted it but it says it’s invalid as they don’t match. I have rechecked the info and it is correct. What can l do?
