Outlook sent emails are disappearing after moving them from the Sent folder to a created folder.

Hi Glen Veno,

Welcome to Microsoft Q&A forum. 

With Classic Outlook + Comcast (IMAP), this usually means the messages are still in the folder but hidden by a folder View/Filter, not actually deleted. Microsoft notes that when items “disappear” from a folder, it’s commonly because a filter was applied to that folder’s view.

Also, the large number in square brackets (e.g., [6709]) typically indicates Outlook is showing the total item count for that folder (read + unread), so Outlook still believes the folder contains mail.

Please try these steps :

1 Reset the folder view

• Select the destination folder (e.g., “A Troop”) > View tab > Reset View

2 Clear any filters on that folder

• View > View Settings > Filter… > clear/remove any criteria (dates, unread-only, etc.).

3 Re-sync / subscribe the IMAP folder (if the folder is out of sync)

• Right‑click the top of the Comcast mailbox in the folder list > IMAP Folders… > Query > select the folder > Subscribe > OK, then right‑click the mailbox again > Update Folder List.

4 If it still looks wrong, reset all views

• Close Outlook > Win + R > run: outlook.exe /cleanviews (this resets Outlook views back to defaults)

As a quick sanity check, it also helps to confirm whether the messages landed in Trash/Deleted Items in Comcast webmail (IMAP moves can behave like copy+delete depending on server behavior).

Please feel free to let me know if you have any further updates, thanks.
