According to a recent disclosure by unidentified `inside' sources at Microsoft, the software giant is currently carrying out a trial of an Outlook edition for Windows RT, the Windows version which runs on the company's ARM-based Surface RT tablets.

As per a recent report by well-linked Microsoft observer Mary Jo Foley, citing the information shared by reliable sources `in the know of' the proceedings at Microsoft, even though Microsoft has an ARM version of Outlook, the company's internal politics has clouded the future of the that particular Outlook version.

At present, Outlook ships only with those Windows RT devices which feature the Home & Business edition or higher, most of the Windows RT users - including the owners of Microsoft's own-branded Surface tablet - do not have any serious business messaging and collaboration on their devices.

Foley's sources have revealed that while some executives within Microsoft would like to bring about a change in that situation, others are probably of the opinion that the existing Windows RT package should be kept the way it presently is. Some of those Microsoft executives also seemingly feel that an acceptable solution would be to rename the existing Windows RT Mail app to Outlook.

However, the main issue which needs to be dealt with is that till Microsoft has built Outlook RT as a Windows Store app, it would not be possible to load it onto the already-available Windows RT devices, particularly since the Windows RT version only allows the installation of Windows Store apps!
