How to Unmark Gmail Messages for Deletion in Outlook
Product
Microsoft Outlook
Device & OS
Windows
Scenario
Managing a Gmail IMAP account within Microsoft Outlook.
Observed behavior
Messages appear with a strikethrough indicating they are marked for deletion. Hiding the messages does not resolve the issue, and the user wants to clear the deletion state so the emails can be kept normally.
Before you start

Log in to your Gmail account via a web browser to check if the affected messages still exist in your inbox or if they have been moved to the Trash or Archive folders on the server.

Check Outlook View Settings and Undelete

Strikethrough formatting can sometimes be a visual artifact of the current view, or it can be reversed using the built-in Undelete function for IMAP accounts.

In IMAP accounts, Outlook sometimes marks items for deletion (displaying them with a strikethrough) instead of immediately moving them to the Deleted Items folder. You can clear this state using specific menu options or by resetting your view.

1
Select the marked messages

Click on the email or hold down the Ctrl key to select multiple emails that have the strikethrough formatting.

2
Use the Undelete command

Navigate to the 'Home' tab on the Outlook ribbon, locate the 'Delete' group, and click on 'Undelete'. This should remove the deletion mark.

3
Reset the View

If the strikethrough persists, go to the 'View' tab, click 'Change View', and switch to 'Compact' or 'Single' to refresh the display settings.

Check Outlook View Settings and Undelete
Important: Simply choosing 'Hide Messages Marked for Deletion' in the View menu does not unmark them; it only hides them from your screen. The IMAP deletion state must be actively cleared.

Frequently Asked Questions

Why does Outlook strike through my Gmail messages instead of deleting them?

IMAP accounts in Outlook sometimes mark items for deletion with a strikethrough instead of immediately moving them to the Deleted Items folder. This depends on your account's Purge options and view settings regarding how deleted items are handled.

Does hiding deleted messages in Outlook unmark them?

No. Changing your view to hide messages marked for deletion only removes them from your screen. To actually unmark them and keep the emails, the IMAP deletion state must be cleared or the message must be restored using the Undelete command.

How do I stop Outlook from marking IMAP items for deletion in the future?

You can change this behavior by going to File > Account Settings > Account Settings. Double-click your IMAP account, select 'More Settings', go to the 'Advanced' tab, and adjust the 'Deleted Items' handling preferences, such as choosing to move deleted items to a specific folder instead of just marking them.

Will permanently deleting the message in Outlook also delete it in Gmail webmail?

Yes. Because IMAP synchronizes your email across all devices and the server, purging or permanently deleting an email in Outlook will also remove it from the Gmail server.
