In January 2014, Adobe announced that Workspaces on Acrobat.com would be retired in 2015. Adobe Workspaces, including Buzzword, Tables, and Presentation, were retired on January 6 2015. As a result, Adobe’s online services at Acrobat.com are no longer an option for hosting Shared Reviews with Acrobat versions 9, X, and XI. It is also no longer an option for collecting forms data in Acrobat versions 9 and X.
Options that relied on Acrobat.com Workspaces were removed starting with a quarterly release May 13 2014.
Adobe exited the document authoring business for word processing, spreadsheets, and presentation files. Adobe's focus is to continue to provide world-class PDF creation and conversion products and services that enable our customers to take actions on their files anywhere on any device.
You can host shared reviews or forms data collection on local network server, web server, or SharePoint.
