Hi there TrojanDeke99,
We're not quite sure what the exact issue is with your app-specific password for the Outlook Mail app on your iPhone. Just in case, here are the steps to take for generating an app-specific password for your reference: Sign in to apps with your Apple ID using app-specific passwords
We'd like to confirm more details to better understand what's happening, along with ruling out some possible causes:
- What's the issue happening with this and the Outlook Mail app? The more details you provide, the better we'll understand the issue.
- Have you been able to use this feature in the past, and if yes, when did this start?
- Sometimes unexpected behavior can be resolved with a restart: Restart your iPhone
- If you have a compatible iPhone model, the latest version is iOS 16.2. You can verify this within Settings > General > About. In case you needed it, this link shows how to first back up, then Update your iPhone or iPad.
Cheers!
