Using Outlook for iOS in business environments for email and scheduling
Hi Steve Fehervari
Welcome to Microsoft community.
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, in addition, you can also try the following suggestions to try to fix this issue.
Recently msn/Hotmail/Outlook/live mail address has no longer support for IMAP or POP3 and it must use the latest modern authentication, please delete your account from your mail app and re-add your account, choose outlook.com as your provider.
- Go to Settings > Mail, then tap Accounts. If you are using iOS18 you will need to find Mail inside Settings > App.
- If you already have your account, tap your mail address and delete it first.
- Tap Add Account, then select your email provider, Select Outlook.com (preferred) or Exchange.
- Enter your email address and password. Server setting will be automatically detected for you.
- If you see Next, tap Next and wait for Mail to verify your account.
- If you see Save, tap Save.
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?
Did you encounter this issue during the process of adding an account? Or did you add your account successfully but have problems sending and receiving emails? Or maybe the in-app keeps prompting you to re-verify your account?
4. Have you tried to re-add your account?
Re-adding can solve some of the problems caused by authentication, and be sure to note that when re-adding your account, choose Outlook.com as your mailbox service provider (protocol)
