The object <security/distribution group> has been corrupted

So again, I've spent time searching but can't seem to find a solution to this issue. When looking at my distribution groups after my move from Exchange 2003 to Exchange 2010 I get the following error when running
Get-DistributionGroup

WARNING: The object domain.com/E-mail Groups/Mail Groups - Offices/Green Bay Office has been corrupted, and it's in an
 inconsistent state. The following validation errors happened:
WARNING: Property expression "Green Bay" isn't valid. Valid values are: Strings formed with characters from A to Z
(uppercase or lowercase), digits from 0 to 9, !, #, $, %, &, ', *, +, -, /, =, ?, ^, _, `, {, |, } or ~. One or more
periods may be embedded in an alias, but each period should be preceded and followed by at least one of the other
characters. Unicode characters from U+00A1 to U+00FF are also valid in an alias, but they will be mapped to a best-fit
US-ASCII string in the e-mail address, which is generated from such an alias.

I've tried to figure out what I'm supposed to do to move this into a consistent state, but I'm lost as to what. Any advice would be much appreciated!

Thanks in advance.

Well, never mind! I stumbled across the answer. Apparently that alias name for this distro group had a space in it and this was making Exchange 2010 cranky. Running

Set-DistributionGroup -identity "Green Bay" -alias "GreenBay"

Fixed the issue and I don't get that error any more. Hopefully I didn't break anything while trying to fix!

Yeah - if you go into EMC, and go into the Distribution Group section under Recipients, it should complain about it. Aliases for anything can't have spaces or '@' in them.
