"We're excited to announce an update to OWA in Exchange Online that now integrates the Office Web Apps into the attachment previewing experience for Word, Excel, and PowerPoint files!," announced Exhange team.
Adding, the Exchange team officials said "Along with continued PDF support, this means Exchange Online users get high-fidelity previews of Office documents on the web, in exactly the same format they were created."
"WebReady Document Viewing is perfect for quick document previews and if you need to edit a document you can easily open the file in your desktop Office client from the Office Web App through a single click."
WebReady Document Viewing lets "OWA users preview attached Microsoft Office documents and PDFs in a web browser without having to save them to disk or open them in a locally-installed application. We continued to offer this functionality in Exchange 2010, but we received a lot of feedback that text and formatting of Office documents were sometimes not the same as the original document when viewed in the desktop Office client applications," explained Exchange team officials.
