Sometimes blogging could mean trouble, especially when you are writing about sensitive data.  Jason Langridge, a Microsoft employee of the the U.K. office of Microsoft's Windows Mobile unit, has accidentally revealed an update of Office Mobile not available for weeks.

He even provided on his blog a download link, but the update was just an internal test version. The update addresses a flaw that left some mobile users unable to open Office 2007 files. Few hours after the initial post, the download link was promptly removed and

Langridge explained what happened in a new notice on his blog.

“Yesterday I blogged about an Office Mobile upgrade and then had to remove the posting. This was because in the final preparation our Product team posted an internal site that was not intended for public consumption and it was then immediately removed. A number of bloggers and Windows Mobile sites picked up on the post our web team made.

I've had a number of questions relating to what happened to the link and when the upgrade will be available. Microsoft will put out upgrades for Office Mobile to support the new Office 2007 file formats in the near future.

In the next few weeks you will see more information pertaining to the availability of this upgrade.” he wrote.

Still there were some users who had downloaded the update.  According to media reports thanks to the update Office Mobile users will be able to view and edit Word documents created in Office 2007 as well as view Excel workbooks and PowerPoint slides created in Office 2007.
