Many companies block the ability to allow incoming email into SharePoint. Many people need to keep mails for many different reasons.
While you can drag and drop multiple documents into SharePoint 2010, that doesn’t work when you try drag emails directly from Outlook.
Rename the emails in Outlook first by opening the mail and changing the subject line. When you’re done, hit the Escape key and you will be asked to save the mail. Say yes. That way, when you upload them, you don’t need to do any work on them and they are easy to find. If you’re saving correspondence, use things like :
2012-08-29 – Tell Joe we need a copy of his ID for the booking.
Using the date format above, you’ll have a sequential log of the events nicely saved in your libraries.
