And sure the most important thing I forgot, SBS 2008 Server FE SP2, Exchange 2007 SP1 . Migration was performed earlier but I wasn't in this firm so I don't know how was performed. I think that migration was performed on SBS 2003 ->SBS 2008 but not on exchange entirely.

Take a look at these links which will help you resolve the invalid aliases. This is common when you migrate from pre 2007 Exchange to 2007. I used these scripts and did some of my own customization to fix invalid chars. http://www.expta.com/2010/03/fixing-leading-and-trailing-whitespace.html http://msexchangeteam.com/archive/2007/06/15/441802.aspx Exchange & Powershell Geek View my MCP Certifications
