Outlook Mail Removing Flagged Emails

Question

My flagged emails are disappearing from the Tasks List view in Outlook. I have emails saved here to reference easily and now I can't find them. Any advice on how to recover?

Answer 1

If your flagged emails are disappearing from the Tasks List view in Outlook, it could be due to a filtering issue or the items not being processed correctly. Here are a few steps you can take to try to recover them:

1. Check Filtering Options: Ensure that no filters are applied that might be hiding your flagged emails. You can do this by going to the View tab, selecting View Settings, and checking the Filter options.
2. Use Advanced Find: You can use the Advanced Find feature to locate your flagged emails. Go to the Search tab, select Search Tools, and then Advanced Find. Make sure to search for all types of Outlook items and check the relevant folders.
3. Check the To-Do List: Sometimes flagged emails might not show up in the Tasks List but can still be found in the To-Do List. Check if they appear there.
4. Review Junk Email Settings: If emails are being flagged as junk, they might be deleted permanently. Review your Junk E-mail Options to ensure that suspected junk emails are not being permanently deleted.

If these steps do not resolve the issue, consider checking your Outlook settings or reaching out to your IT support for further assistance.

Hi @Jennifer Burke,

Thank you for posting your question in the Microsoft Q&A forum.

I can understand how inconvenient it can be when your flagged emails disappeared. This behavior can happen because in the new Outlook, only flagged emails from your primary mailbox appear in Microsoft To Do. Flags set in shared mailboxes or shared folders do not sync to To Do, so they won’t show up in the Flagged email list. To Do also loads only the most recent 100 flagged messages from the last 30 days, which means older or very large numbers of flagged items may not appear. Since the classic Tasks module has been replaced by To Do in the new Outlook, flagged emails won’t show in the old Tasks view either, they only appear in To Do’s Flagged email list or through Outlook search and filters.

Here are a few steps that often help:

1/ Open Microsoft To Do and turn on “Flagged email”:

In To Do, select your profile picture > Settings > ensure Flagged email is On. Then select Help & feedback > Sync to refresh.

Reference: Using Microsoft To Do with flagged email from Outlook

2/ Use Outlook’s built‑in filter:

In New Outlook, click Filter (above the message list) and choose Flagged to list all flagged messages.

3/ Search for flagged messages if Filter isn’t available:

In Outlook’s search box, use IsFlagged:yes to return flagged mail across folders. You can scope the search to a specific folder if needed.

4/ Confirm the message location:

If the missing items were moved to another account, shared mailbox, or Online Archive, move them back to your primary mailbox and re‑flag if necessary, only primary‑mailbox items sync to To Do’s flagged list.

5/ Re‑sync To Do if it looks stale:

• Sign out from both Outlook on the web (outlook.office.com) and Microsoft To Do (to-do.office.com). 
• Close all browser tabs related to Microsoft 365 to ensure there are no active cached sessions. 
• Open your browser settings and clear temporary internet files, cookies, and cached images. 
• For accuracy, choose the option to delete cached data for at least the last 7 days. 
• Once cleared, close and reopen the browser fully (do not just refresh). 
  

6/ Submit feedback:

If you've tried all the above steps and the issue still persists, I highly recommend submitting a suggestion directly from Outlook by navigating to: Outlook (new) · Community portal. This is the most effective way to ensure your voice reaches the product team and can be considered for future improvements.
