Question marked as
1 - Your Optonline.net email may have stopped working because your password needs to be entered again, the account settings changed, or the Mail app needs to reconnect.
2 - On your iPhone 17 Pro Max, go to Settings >> Apps >> Mail >> Mail Accounts and select your Optonline account.
3 - If you see a password prompt or an error, enter your password again.
4 - If that does not fix it, remove and add the account again as previously suggested by @ IdrisSeabright
5 - Make sure you know your email password first. Go to Settings >> Apps >> Mail >> Mail Accounts >> select the account >> Delete Account, restart your iPhone, then add it back using Add Account >> Other.
Apple’s instructions for adding or removing email accounts are here: Apple Support: Add an email account to your iPhone or iPad
6 - If you still have trouble, check whether your Optonline email works in a web browser.
7 - If it does, the issue is likely with the iPhone Mail settings.
