Microsoft officials aren't sharing many specifics about which job functions and geographies will be hit hardest by the coming layoffs of 7,800 announced today, beyond saying the bulk of the cuts will affect Windows Phone hardware.

But there are a few more details trickling out.

Microsoft will lay off more than half of the Microsoft staffers based in Finland, the home of Nokia, as reported by Yle. That means a maximum of 2,300 jobs will be cut in Finland "as the company shuts down its Salo operation and moves tasks from there to Microsoft facilities in Tampere and Espoo," according to Yle. Currently, there are 3,200 Microsoft employees in Finland, Yle said.

A Microsoft spokesperson confirmed that this report is correct.

Salo, where Microsoft had been manufacturing Lumia phones, was also hit hard in last year's round of layoffs. One of my contacts said that Microsoft also plans to close San Diego and some of its Beijing facilities involved with Windows Phone hardware.

It seems that Microsoft marketing and sales also will be hit with cuts as part of the layoffs. Again, Microsoft officials are not specifying how many of the 7,800 cuts will be in manufacturing vs. design, engineering and sales/marketing.

An e-mail memo from Microsoft's Chief Operating Officer Kevin Turner to the troops sent today, July 8, notes there will be some "direct impact" on Microsoft SMS&G (Sales, Marketing and Services Group). There may be additional "reductions" in SMS&G coming around the world in Microsoft's fiscal 2016 (which runs from July 1, 2015 to June 30, 2016) -- as a result of the phone-hardware cuts, as well as Microsoft's recent moves to pull back from the display ad business -- Turner noted.

Turner told employees that Microsoft "will also focus on the channels and markets that offer the best returns," going forward with Windows Phone. "This is a similar approach to the one we have taken with Surface, which has been very successful," he said in his e-mail.

Bloomberg Business Week's Dina Bass tweeted today that she was told Microsoft will be narrowing its carrier/geography focus with Windows Phone by exiting relationships and areas where it has not been successful. Bass noted, however, that Microsoft is still planning to continue to offer devices in the U.S., where its share and carrier relationships have been less than stellar.

Turner also mentioned some organizational changes resulting from Microsoft's display-ad exit in today's e-mail. One of those changes is that Rik van der Kooi will be moving from Microsoft's Applications and Services Group to Turner's organization, taking with him Microsoft's search-ad team.
