Hi RITA SVARZKOPF,
Welcome to Microsoft Q&A Forum,
Thanks for sharing your concern on Outlook-Microsoft Insider, I acknowledged that you would like to put the deleted emails on Outlook to Gmail trash.
For more detail in the above steps, you can consider checking the below troubleshoots and reference if you want:
How do I enable the All Mail, Drafts, Sent Mail, Spam, and Trash folders in Gmail or G Suite IMAP?
New Outlook (Insider) — Gmail account connected: If you ever need to restore, use Deleted Items → Recover items deleted from this folder (new Outlook), then move them back to the desired folder.
Recover and restore deleted items in Outlook
Classic Outlook (legacy UI) — IMAP account: If you’re using the classic Account Settings dialog for an IMAP profile, map the delete action explicitly to Gmail’s Trash:
- Select File → Account Settings → Account Settings.
- Choose your IMAP account → Change → More Settings.
- Open the Deleted Items tab.
- Select Move deleted items to the following folder on the server → choose [Gmail]/Trash.
Notes that help with Gmail IMAP:
- If you previously chose “Messages are marked for deletion,” Outlook will show deleted messages with strikethrough in their original folder (not moved). Switch to Move deleted items… to use Trash instead.
- If strikethrough messages still appear, change view to View → Change View → Hide messages marked for deletion.

I hope the details on the above workarounds will help you more in this case. Even if not, please do not hesitate to share with me more information regarding your error message, so we can find the solution together.
Thanks, and sincerely,
