I just moved to Windows 7 having previously used the SharePoint (MOSS 2007) lists feature in Outlook 2007 on WinXP for some time now with great success. It seems that now when I open a document through Outlook from a SharePoint list it opens in read only mode. Or, at least when I try to update the document on the server I get a message stating that the document is read-only. The really odd thing is that if I check the document through my browser it is checked-out to my user account. Any ideas? Thanx! Stephen

I have also found that by turning off Check-in/out, the use of SharePoint lists within Outlook works just fine. So, this issue only appears when documents must be checked out.

document library items are stored in read-only PSTs, but you're able to modify items that were created by Word 2007, Excel 2007, or PowerPoint 2007. When you open such items, a Message Bar appears at the top of the document, and you can click Edit Offline. The local copy of the changed item is stored in the SharePoint Drafts folder in My Documents. Thereafter, Outlook 2007 accesses the local copy, not the PST. You can also check out the item from SharePoint when you're online by using the Check Out feature and selecting "Use my local drafts folder"; you'll automatically be able to modify the document offline with this method. After you modify the item and exit the application, a check is performed to see whether you're online and the item can be updated on the SharePoint site. If not, it stays in the SharePoint Drafts folder until you open it again, but the document will have an icon to show that it was modified, and it will also appear in your SharePoint Drafts Search folder in Outlook. When you connect to SharePoint later and open the changed item, a dialog box appears to let you update the changes to the server. You need to open every modified item from the SharePoint Drafts folder; Outlook won't notify you automatically to update these items.
