A family of Microsoft word processing software products for creating web, email, and print documents.
Seems kind of strange that for an image on my own computer, I would need internet access to add it as a custom bulletpoint.
It seems to be fixed when using a different microsoft account. I bought my laptop and log into it with my personal MS-Account. When opening word, it automatically uses that account, which doesn't have a licence.
As a student, my school also provided me with a microsoft account and a licence to use MS-Office. When using that account on MS-Word, it does work to add custum bullet points.
