Quick answer
The SquirrelMail lesson is historical. For an Interactive Online mailbox using Roundcube now, roundcube folders organize server mail and can synchronize with other devices. Deletion can affect the same mail elsewhere.
Applies to
For an authorized mailbox user. Interactive Online manages settings only for mail hosted on the selected service; mail hosted elsewhere uses that provider's settings. The preserved lesson shows an earlier interface.
Steps
- Open the intended application or account and confirm its complete mailbox address and provider.
- Open Settings > Folders to create or manage the intended folder and its parent. Review subscription/display controls before assuming a folder or its contents are missing.
Check the result
Verify the equivalent task in the actual available webmail application. The old SquirrelMail screen is not evidence that it is enabled on this account.
Troubleshooting and support
If the task is tied to a SquirrelMail-only preference, use the current webmail application's supported equivalent rather than installing the obsolete interface.
Contact support from the owning account with the domain, product/version, exact error, time/time zone and redacted evidence. Exclude credentials, session URLs, payment details and private customer records. Confirm any separate application-support scope.
