We have several computers running XP Professional, a server running SBS 2008 and a newer laptop running Windows 7. Historically, we have created client folders that each contain all of the files we have relating to a particular matter (eml, doc, xls, pdf, etc). We use the "list details" view when opening folders, with the documents sorted according to the date they were last modified. We have used Outlook Express as our email client.
This worked beautifully until we introduced the server and latest laptop into the set up. The problem we have is that if a folder is opened directly from the server or from the laptop running Windows 7, all of the Outlook Express files in the folder are automatically modified in someway and listed as modified on the then current date. This happens regardless of whether any of the .eml files is actually opened (it seems to be enough to open the folder in which they are contained). The result is that we go from having a handily arranged list of files in a "true" date modified order to a situation in which all of the .eml files in the folder appear as modified on the current date.
We are able to open the .eml files from these machines using Live Mail or another viewer, but tend not to ever visit saved folders from them in view of the problem mentioned above.
With Microsoft withdrawing support for XP in 2014 we are soon going to have to confront the problem of migrating from XP to Windows 7 or 8 and would love to have a solution to this problem before the move.
