I'm reaching out for assistance regarding an issue one of our users is facing. The user utilizes the OnePlaceMail add-in with Outlook on her desktop.

The problem is as follows:

The pop-up prompt to inquire whether she wants to save or upload a new email is not functioning. This feature was operational before but has ceased to work recently.

Additional information:

No recent updates have been made to her system.
Outlook 2016 is being used.
The user's desktop runs on Windows 10.

I have already attempted to resolve the issue by reinstalling the OnePlaceMail add-in.
Any guidance or support on this matter would be greatly appreciated.

Thank you in advance for your assistance.
