Exchange Server 2007 (The HTTP Filter DLL C:\.......\AirFilter.dll failed to load . The data is the error.

Hello guys,

I'm testing some stuff in my  virtual Lab. I have 1 DC 2008 SP2 with Ex2007SP1 + 1 Transport Edge 2008 SP2 - EX2007SP1 .

I added 2 new Servers in my "domain.local"  : DC2012 and 2012R2+EX2013.

To respect the coexistance of Ex07 and Ex2013 i had to upgrade Ex07 to SP3. The upgrade was perfect and it didn't show any issue but the localhost/owa does not work . I didn't find nothing regarding this error , I found 3 articles  but they were useless.

Could You please Help me ? Now i'm installing RU10 .

Thank You,

Alexander
