Can't send AOL email from my iPhone

• Tap Settings
• Tap Mail
• Tap Accounts
• Tap the AOL account
• Follow the instructions you just posted

Or, the easier way:

• Tap Settings
• Tap Mail
• Tap Accounts
• Tap the AOL account
• Tap Delete Account
• Restart your phone→Restart your iPhone - Apple Support
• Tap Settings
• Tap Mail
• Tap Accounts
• Tap Add Account
• Tap AOL
• Follow the instructions

This should look up all of the needed settings

The outgoing mail server is smtp.aol.com. There are instructions on aol’s site for manually setting this. The problem is that their outgoing mail server has been down sporadically for over a month. So outgoing messages sit in the Outbox in the Mail client until a connection with the server can be made. Sometimes it’s been a minute, sometimes it’s hours. This is an AOL problem, not an iPhone problem.

smtp.gmail.com is not a Microsoft server.

You need to follow AOL’s instructions and add an outgoing server for AOL, and turn off the gmail entry. Those instructions were in your first post; you just have to go to Settings/Mail/Accounts and follow those instructions.

Sorry, my error. SMTP.gmail.com is not an AOL server.
