Hi@Woody Chiu at RASI , thanks for reaching us.
I understand you are experiencing an issue where the "Your privacy matters" dialog keeps popping up every time any of the Microsoft 365 applications opens.
The "Your privacy matters" dialog is a consent prompt that appears when an application requests permission to access a protected resource in Microsoft 365.You can choose whether to use these experiences or not, but the dialog box will keep appearing until you make a decision.
To disable the "Your privacy matters" dialog in Office 365 applications, you can follow these steps:
1.Open any Office 365 application, such as Word or Excel.
2.Click on File, then select the Options.
3.From the Options window, Click Trust Center -> Trust Center Settings
4.Click Privacy Options -> Privacy Settings
5.Uncheck the "Turn on optional connected experiences" box -> click ok.
6.Restart the office applications.
After completing above steps, the "Your privacy matters" dialog should no longer appear when you open Office 365 applications.
Hope this helps. Do let us know if you any further queries.
Thanks,
Navya.
