Microsoft making the shift to web 2.0

We developed our new Office products in response to a shift in how people and businesses use technology today. The line between home and work has blurred, so people want more choice and flexibility in how, where and when they work. They’re also demanding the ability to access and effectively manage their information whether at home, at work or on the go.

With these new products we are giving people a familiar interface across PCs, mobile phones and browsers to make it even easier for them to create, communicate and collaborate from any location.

By listening to our customers, we know that people want to stay connected to each other. They want an easy way to bring their ideas to life, and they want the freedom to use Office from more locations and on more devices.
Exchange 2010 will include integrated archiving and multi-mailbox search capabilities at no extra cost, making it easier for companies to, for example, comply with e-discovery requirements.

Exchange 2010 will power a number of new features, including the ability to view e-mail conversations in threaded form a la Gmail, and a button to ignore e-mail threads.

Outlook Web Access will include an instant messaging client compatible with Microsoft Office Communications Server and Live Messenger. Microsoft will offer APIs to allow other third-party IM clients to work in Outlook Web Access
Microsoft's Software + Service strategy has rapidly matured and is native to Exchange 2010. This architecture of a single environment that spans on-premise and cloud-based gives large firms an opportunity to leave some mailboxes on-premise and host others in the cloud to save money without incurring admin hassles.

Exchange 2010 is the first product that Microsoft has engineered to run as well in the cloud as on-premise. That means it will be easier to split your domain and run a single managed environment (meaning one admin console, one archiving management tool set, one legal hold implementation, one message filtering solution) across an on-premise and cloud-based implementation.
"Spam overwhelms e-mail messages" by Darren Waters, BBC:
More than 97% of all e-mails sent over the net are unwanted, according to a Microsoft security report. The e-mails are dominated by spam adverts for drugs, and general product pitches and often have malicious attachments.

It also found that Office document attachments and PDF files were increasingly being targeted by hackers.
