The customer relationship management service Salesforce will be making a number of new partnership deals with Microsoft, including a new Salesforce1 Mobile app for Windows 10 that will be released sometime in the second half of 2016.
You may remember that Salesforce announced plans for a Salesforce1 Mobile app for both Windows 8.1 and Windows Phone some time ago. That app went into invite-only testing in 2014. However, a more recent post on Salesforce's support forum confirms that the company has decided to move ahead with supporting Windows 10:
"The downloadable container/app for Windows 8.1 is still in preview and will stay in preview indefinitely as we are shifting our focus to build an App for Windows 10, given MSFT's shift in focus shift here as well."
Salesforce has also announced plans to integrate Microsoft's OneNote and Skype for Business to the company's Salesforce Lightning Experience, along with adding Salesforce content in Office Delve. All of these features are expected to become available sometime in the second half of 2016.
