need password reset on smtp

Hello SRK69,

Thanks for posting in Apple Support Communities.

Do you use more than one Apple ID/iCloud account? If so, we'd confirm you're attempting to put in the correct password to the iCloud account. In case you forgot the password, use these steps to reset the password: If you forgot your Apple ID password

Is this issue happening in the iCloud for Windows app? If so, you may need an app specific password, as described here: Set up iCloud Mail, Contacts, and Calendar in Outlook on your Windows computer

Set up iCloud Mail, Contacts, and Calendar in Outlook on your Windows computer

You can view your iCloud mail, contacts, and calendar in Microsoft Outlook.

Before getting started, make sure you’ve set up an @icloud.com email address. See Create a primary email address for iCloud Mail in the iCloud User Guide.

1. On your Windows computer, open iCloud for Windows.

2. To set up Contacts and Calendar, select “Contacts and Calendars,” click Apply, then follow the onscreen instructions to set up Outlook.

3. Note: If you see “Mail, Contacts, and Calendars,” selecting that option also sets up your iCloud Mail account.

4. To set up Mail, sign in to Outlook using your Apple ID email address and an app-specific password. See the Apple Support article Using app-specific passwords.

For troubleshooting steps, see the Apple Support article If you can’t add iCloud Calendars, Mail, or Contacts to Outlook.

To learn how to set up iCloud Mail, Contacts, and Calendar on your Apple devices, see any of the following in the iCloud User Guide:

* Set up iCloud for Mail on all your devices

* Set up iCloud for Contacts on all your devices

* Set up iCloud for Calendar on all your devices

Let us know if that helps out or not. If not, please include some additional information. For example, are you receiving any error messages? As that will help us to move forward.

Have a lovely day!
