Microsoft is preparing to roll out the new SharePoint Online as a part of Office 365. As a result of this initial phase of the SharePoint Online service update, you may be affected by some of the design changes. Below is a consolidated list of items with pointers to documented fixes and posted workarounds: Install SharePoint Designer 2013 (free download here ). Previous versions of SharePoint Designer are not compatible with the new SharePoint Online. Apply the Hotfix for SharePoint Designer 2013 to work properly with InfoPath 2010 – start here . Apply the Hotfix for SharePoint Workspace 2010 to work properly with the new SharePoint Online - start here. In addition to the above items, there are several known issues previously posted here that Microsoft is working on to resolve in real-time. These issues are not broadly impactful and most have a corresponding knowledge base (KB) article with posted manual solution steps. Note that you will not yet have access to the new SharePoint features or the new user interface. Rather, during this preparation phase, you will only see the new enhancements to the Office Web Apps as we previous communicated here . In addition, we’d like to reiterate Office 365 no longer supports Internet Explorer 7 (IE7). Some CRM Online customers are also impacted within this phase of the SharePoint Online service update. Please review the in-depth blog post that articulates the recommended “list component” fix here . Thank you, The SharePoint Online Team * The Office 365 ProPlus Preview can run side-by-side with previous versions of Office. Users who have use rights to Office as a subscription will have the use rights to final Office 2013 RTM once available and no longer need the Preview version.
