Hi @kody
Do I need to active the via internet?
If you use MAK key to activate volume licensed Office 2021, yes, you need the Internet connection.
Besides, please ensure your MAK key is correct.
But if you have no condition to connect to Internet, I suggest you choose "I want to activate the software by phone."
- To get the Installation ID (IID) for offline activation for Office 2021 , you may run following command in Command Prompt (Run as administrator).
cscript.exe "%ProgramFiles%\Microsoft Office\Office16\ospp.vbs" /dinstid
- After you enter the IID into the interface of the Phone Activation Wizard, you will get the Confirmation ID (CID) via phone, please continue to enter its value in Command Prompt to activate Office.
cscript.exe "%ProgramFiles%\Microsoft Office\Office16\ospp.vbs" /actcid:value
Any issues, welcome to post back.
