Get message, “This message has not been downloaded from the server” I have not received any new emails on my I Phone

Dear Lynda K Hegman

Welcome to Microsoft Community.

It doesn't sound like your account has been hacked, just experiencing some issues that may be related to server synchronization. The message "This message has not been downloaded from the server" strongly suggests a problem with your email account's connection, not necessarily a hack.

First of all, I would like to apologize to you for the fact that I am using translation software to communicate with you, so please correct me if I have misunderstood you, and thank you for your understanding.

Please use Microsoft Outlook, or visit outlook.live.com for the moment, there seems be a temporary problem that need to be further fixed by Apple, I'm sorry for the inconvenience.

As a matter of fact, recently a lot of users are responding that they are experiencing the problem of not being able to sync emails or add accounts on their mobile devices (iOS is the majority), which may be a popular issue, maybe you need to wait for Apple to fix this issue, in addition, you can also try the following suggestions to try to fix this issue.

But first I'd like to know more about your issue, you can tell me:

1. what email app are you using?

Are you using mail app or Outlook for iOS when you have this problem?

2.What is your iOS version?

Please make sure your iOS version is not lower than iOS18, the latest iOS contains the latest updates and features, needs to use the new style authentication, which needs the latest features support.

3. When did you encounter this problem?

You mean stop working, is it not syncing mails? Did you encounter this problem during the process of adding an account? Or did you successfully add your account, but are having trouble sending and receiving email? Or maybe the application keeps asking you to verify your account again?

4. Have you tried to re-add your account?

Have you tried to re-add your account via the following steps? Or you can tell me about your actions :)

1. Go to Settings > Mail, then tap Accounts. If you are using iOS18 you will need to find Mail inside Settings > App.
2. If you already have your account, tap your mail address and delete it first.
3. Tap Add Account, then select your email provider, Select Outlook.com (preferred) or Exchange.
4. Enter your email address and password. Server setting will be automatically detected for you.
5. If you see Next, tap Next and wait for Mail to verify your account.
6. If you see Save, tap Save.

Also you can see these articles from Apple:

If you've found something else worth noting, please contact me and tell me about it, I'd love to solve the problem with you, thank you for your cooperation and understanding. :)
