Hi, welcome and thank you for your question. My name is ***** ***** I am glad to assist you today.
I am very sorry about your issues. So your email address is ending with @hotmail.com, all other devices are able to get emails, but the iPad shows an error. Right?
Now, using your computer or phone, please use a web browser (not the Mail app), go to http://hotmail.com, and then enter your full email address as the username, then enter your password, and Sign In. Please tell me when you are able to sign in successfully.Please let me know by replying to me here so that I can help you further.
Yes, we can resume with this when you are back and available :)
Please take your time....
You're welcome. Till later then...
