Hi there! I understand that you're experiencing an issue where deleting an older email in a chain causes all emails involved in that chain to be sent to the trash. I'm here to help!

To clarify, could you let me know what email client you are using on Tuta? Are you accessing it through a web browser, or are you using a different method? Additionally, have you experienced this problem consistently, or is it happening intermittently?

Once I have a bit more context, I can guide you through some potential solutions!

web browser, chrome. My wife has an account as well and is seeing the same behavior.

Thank you for the additional information! It’s helpful to know that both you and your wife are experiencing this issue while using Chrome to access Tuta. Let's work through some steps to resolve it.

1. Clear Browser Cache and Cookies:
- Open Chrome and click on the three dots in the upper right corner to open the menu.
- Go to "More Tools" and select "Clear Browsing Data."
- Make sure "Cookies and other site data" and "Cached images and files" are checked.
- Click on "Clear data."

2. Check Your Email Settings:
- Sometimes, email clients have specific settings that may affect how emails are deleted. Log in to Tuta and check your email settings to see if there’s an option related to threaded conversations or email chain management. Make sure there are no options enabled that cause multiple emails to be deleted simultaneously.

3. Test in Incognito Mode:
- Open a new Incognito Window in Chrome (you can do this by clicking on the three-dot menu and selecting "New Incognito Window").
- Try to replicate the issue in this mode. If you don’t see the same behavior, it might be related to extensions or settings in your standard browsing session.

4. Browser Update:
- Ensure that you are running the latest version of Chrome. You can check this by going to the menu, then "Help," and selecting "About Google Chrome." The browser will automatically check for updates and install them if available.

5. Check for Conflicting Extensions:
- If you have browser extensions installed, one of them might interfere with Tuta. You can disable extensions temporarily to see if this resolves the issue. To manage extensions, go to the menu, select "More Tools," and then "Extensions." Try disabling them one by one.

If the issue persists after trying these steps, let me know. I can assist further or help you contact Tuta support for more specialized assistance. Are you satisfied with the solutions I provided so far?
