Microsoft has announced that 6 months after release, the beta of Microsoft Office Live Workspace has reached the one-million-customer sign-up milestone.

Office Live Workspace beta is the free, web-based extension of Microsoft Office that lets people access their documents online and share their work with others.

As well as milestone, Microsoft has published a list improvements to the Google Docs-rivalling service that Microsoft was criticised as being slow to develop.

The improvements include an at-a-glance activity panel view, email notification alerts about changes to their workspace or docs, direct bookmark links, drag and drop multi file upload, improved sharing and better Firefox support.

Office Live Workspace beta is now available in Brazilian Portuguese, Dutch, French, German, Italian, Japanese, Korean, Polish, Spanish and traditional Chinese.
