Purpose
TuneReplyAll displays a warning when a user is about to reply to all recipients. The user must confirm the choice to reply to all. This helps prevent accidental disclosure of confidential information. If Outlook includes the user's own address in Reply All, TuneReplyAll removes it from the message.
Current version: 1.0.15
The application is a COM add-in compatible only with classic desktop Outlook for Windows. It does not support the new Outlook for Windows.
Installation
- Download TuneReplyAll.zip and extract its contents. Run TuneReplyAllSetup.exe and follow the instructions.
- Run Outlook. Select File > Options > Add-ins and verify that TuneReplyAll appears in the "Active Application Add-ins" list.

Testing
- Open Outlook and find a message that has more than one address in the To: or CC: fields. Click the Reply All button.

- A new message will appear. Confirm that the TuneReplyAll warning appears.

TuneReplyAll has been tested with Outlook 2013, 2016, 2019, and 2021 (both 32-bit and 64-bit).
Uninstallation
You can uninstall the add-in via Settings > Apps (called "Installed Apps" in Windows 11 and "Apps & features" in Windows 10).
