I have not gotten into the Office 365 beta yet and I am very eager to have a good look at it. I did however find some good documentation on the different services. You can find documentation on Microsoft Exchange Online, Microsoft Lync Online and Microsoft SharePoint Online via the link below.

Below is a quick summary of the features I found in the SharePoint Online Standard Documentation that you can find in the link above.

When we are looking at the SharePoint Standard vs. SharePoint Online, SharePoint Online will not support the following:

• Word Automation Services
• Records Center
• Federated Search
• Business Data Connectivity
• External Lists
• Secure Store Service

But on the other hand SharePoint Online will have some Enterprise offerings

• Excel Services
• Visio Services
• Access Services
• InfoPath Forms Services

Some new stuff that SharePoint Online will include is

• Extranet Access
• Anonymous Access
• Single Site Collection Search
• Office Web Apps

All this of course is subject to change because it is in the beta stage!!!!
