We are working on an e-mail archiving project.
As part of this, we are copying content from user's self managed PST files into their online Exchange mailboxes.
It's not a big deal to do this manually, when users have a handful of folders containing their content.
...but when users have a large number of folders doing this one folder at a time can be time consuming, and as a multi-step process this can be even more time consuming if folders contain a large amout of content.
It seems that if you are using Outlook 2003 as a client, you are able to use the folder view (as opposed to mail, calendar, or contact view) right click and drag the top level of the PST into a user's mailbox. This will create a top level folder for all of the content, and complete in a single step.
Unfortunately, when Outlook 2010 is used as the client, this does not appear to be an option.
