The number of subfilters exceeds maximum allowed number of 100
A colleague of mine has been struggling a bit with an Exchange 2010 implementation. CAS and HUB transport roles were deployed successfully but the MBX-role failed to install with the error:
The number of subfilters exceeds maximum allowed number of 100. Processing stopped.
Apparently an e-mail address policy cannot contain more than 100 address templates. Read on for more details: Watch those recipient Policies!!!
Note: an individual recipient cannot have more than 100 e-mail addresses either.
