Exchange still hates me but now i may be getting somewhere

Well, apparently we have some corruption somewhere in our Exchange organization. I ran this command:

Get-MailPublicFolder | Sort-Object -property Alias | Select-Object -property 'Alias', 'Identity' |fl

And the first thing i see is this wonderful error:

WARNING: Object corp.COMP.com/Microsoft Exchange System Objects/Offline Address Book - First Administrative Group has been
corrupted and it is in an inconsistent state. The following validation errors have occurred:
WARNING: "Offline Address Book - First Administrative Group" is not valid for Alias. 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 one of them 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 email address which is generated from such an alias.

I guess i will be calling Microsoft in the morning and using one of those wonderful support incidents we have.

I will let people know what the results are.
