Microsoft on Thursday said it has discontinued the mobile versions of its Dynamics ERP (enterprise resource planning) products.
The first mobile Dynamics product, Dynamics AX Mobile Sales, was introduced in 2007 and let sales people remotely place and track orders, query sales histories and manage advertising campaigns from Windows Mobile devices.
Microsoft also offered development tools for businesses to build their own mobile offerings based on Dynamics.
At the time, Microsoft said it planned to extend other products in the Dynamics family to mobile devices.
Thursday's blog post said that mobile access for Dynamics AX and Dynamics NAV has been discontinued.
Microsoft did not immediately reply to a request for comment.
The software giant appears to have begun sending notes out to users earlier in September. It said that third parties have enabled great mobile applications for Dynamics.
"Due to the broad availability of partner-developed mobile solutions built on these or similar technologies, we have made a strategic decision to discontinue the current development of Microsoft Dynamics Mobile," according to the note, which has been posted online by various customers.
The note also said that no future updates to the product will be provided and it won't be sold past Aug. 31, 2010. Web sites for the products are still live.
Microsoft has discontinued a number of products in the past year.
Between October 2008 and June 2009, Microsoft had stopped selling or scaled back development on at least 12 products, said Matt Rosoff, an analyst at Directions on Microsoft. Other discontinued products include Money and Equipt.
