Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi John,
Thanks for your updates.
I could understand your requirement, I know the white background may affect your eyes.
I am very sorry about the inconvenience for you.
I would like to help you, however, we can’t change the background now.
If you want to add the feature “change the background color” or return to light grey, I suggest you submit this idea at our User Voice or vote this similar idea which is submitted by another customer.
It is the best way to let our develop team hear your voice.
Thanks for your understanding.
