Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Rajesh,
I would like to know from where and how did you purchase and install Office Standard 2013?
Since Office 2013 Standard is a ‘Volume License installation’, it would be best if you get in touch with Volume License support.
