The answer is OWA Admin tool from Microsoft. You can get it from: http://www.microsoft.com/downloads/details.aspx?FamilyId=4BBE7065-A04E-43CA-8220-859212411E10&displaylang=en Good luck...Eric

this tool just work for Exchange server 2003

Hello You can control the size of an OWA signature via a registry key (REG_DWORD) on the Exchange Server. To modify the value of the signature, use a registry editor to navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWeb\OWA The default SignatureMaxLength value is 4096 (4KB) and the maximum value is 16672 (16KB).
