Forwarded emails in Exchange 2010 don't show email address

If you have an version of Exchange prior to 2010 and have a rule set up in an email account to forward all incoming emails, when you migrate to Exchange 2010 the emails will still be forwarded, but they won't show the email address they're from. This is a know issue and is not one Microsoft plans to fix. There are a couple workarounds though:

- Delete the account, recreate the account, and recreate the rule.
- Change it from forwarding to redirecting or forwarding as an attachment.
- If it's forwarding to only one person, you can set forwarding in the account properties.
