"The properties of the message have been changed" prompt when forwarding/replying in Outlook

When users open a message in its own window that has a pdf attachment and replies or forwards the message; when they close the original window, outlook prompts "The properties of the message <email_subject> have been changed. Want to save your changes to this message?"

Steps to recreate this issue:

  • Message must have pdf or txt attachment
  • Open the original message in its own window
  • Reply-to or forward the message
  • Closing original message that was previously opened in its own window

Attempts to disable add-ins or running outlook in safe-mode do not resolve this issue.

Hi All，

First, apologize for the inconvenience caused by this problem in Outlook Client. Microsoft has realized this issue and the dedicated outlook teams are working on this problem to fix it. It is a known issue in the current Outlook Clients, and a fix will be released to Office version 2106 on 2021/6/17. For the affected users please navigate to Outlook Web App as temporary workaround and wait for the new fix release with some more patience, thanks. For more details, please refer to "The properties of the message have been changed" prompt when forwarding/replying in Outlook.

Thanks for your understanding and patience.

Best Regards,

Oliver

    @Scott Shaeffer,

    The issue affects any SKU of Office on Current Channel Version 2105, Update history for Microsoft 365 Apps (listed by date) - Office release notes | Microsoft Docs. When the fix build is available it will update simultaneously for all the SKUs.

    @CJ,

    The issue occurs in Current Channel version Version 2105 (Build 14026.20246+), Update history for Microsoft 365 Apps (listed by date) - Office release notes | Microsoft Docs. After a user updates Office to Version 2105 they will start seeing the issue.

    Will this update be applied for other version of office at that time or only for office 365? I have a number of users experiencing this same issue but we use 2019 and not 365.
