Hi Wallace,

Your problem may occur due to the exchange server OS was not patched though the AD RMS Cryptographic Mode 2 was enabled. To resolve the problem install the appropriate patch on the server OS.

Be informed that, clients must be windows Vista SP2 or upper and must be 2008 R2 SP1 of AD RMS server. Cryptographic change signature support from SHA-1 to SHA-256 and signature and encryption support from RSA 1024 to RSA 2048. To support Cryptographic both server and client require and additional software and at least SP3 required for Exchange 2010.

Hello,

I understand you got an error code while trying to run Microsoft Office after installing Cryptography, you need to update your Microsoft Office.

Try this out:

1) Disable the firewall. 

2) Delete the Catroot2 folder from "C: WindowsSystem32"  folder.

3) Start Cryptographic Services:

   a) Click Start, click Run, type "SERVICES.MSC" and press enter.

   b) Double click the Cryptographic Services and click Start.

4) Then go to the Windows site and update it.
