Problem
Users can send emails and view new messages in their Inbox but cannot access additional subfolders on their iOS devices.
Solution
The issue typically stems from an incorrect IMAP Path Prefix setting. To fix this:
- Navigate to Settings > Mail > Accounts
- Select your email address, then Account > Advanced
- Locate the "IMAP Path Prefix" field at the bottom
- Leave it blank or enter "INBOX"
- Save changes and navigate back through settings, saving as needed
Alternative Troubleshooting: If the above steps don't resolve the issue, consider removing and re-adding the email account entirely on your device.
