Frequently Asked Questions

Which account, file, or app should I use when I open File Explorer and go to the Documents folder?

Open File Explorer and go to the Documents folder. The available Send to OneNote behavior depends on Outlook and OneNote versions. Test one message first, then confirm whether each selected email creates a page or combines content.

What result should appear when I close the deleted notebooks in OneNote so they no longer appear in the?

Verify sender, recipients, sent date, subject, body, attachments, and the destination notebook or section. Confirm the account type, product version, ownership, and permissions before assuming the control is unavailable.

What should I preserve before I open Outlook and select the exact messages?

Not every Outlook voting or actionable-message workflow prevents a later change. The sender must use the capabilities supported by that message type or form. Keep the relevant backup or confirmation until you have checked the result.

Where should I verify the final result after I delete old OneNote notebook files?

Repeat for the remaining items only after the test result is correct. Reopen the affected app or portal and confirm that the expected status persists.
