Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
@Wiz Huang (黃義倫) ,
Welcome to Q&A forum!
According to the information you provided, I tested it with your .xml file on Windows 10 where Office 365 was installed. But since I do not have an Office 2019 license, I can’t fully reproduce your problem. Thanks for your understanding!
Per my test, I found that my Microsoft account will automatically sign in to Office 2019 after installing it.
> It's just autoactivate.
<< Do you mean it will sign in with your account automatically or activate automatically? If it is automatically activated, which activation method did you use?
After installing Office 2019, please open Word or Excel, go to File>Account to view and share a screenshot with us. (Please cover up personal private information, such as account)
Besides, per my research, if you do not want activate Office automatically, you do not need to add this element <Property Name="AUTOACTIVATE" Value="0" />.
This official document states that if not specified, it defaults to 0. Please remove it and reinstall Office 2019 to have a check.
Hope the information is helpful to you. Any updates, please let me know.
