Reducing Mail Security installation time

If you do not have Internet connection on your system, then installing Mail Security may take a long time to complete. Mail Security tries to examine the certificate revocation list (CRL) to verify the code signing certificate each time that Mail Security compiles an assembly into managed code. When Mail Security is not connected to the Internet, each CRL request may time out before the installation can continue and increases the installation time.

To reduce Mail Security installation time

  1. Start Internet Explorer.

  2. On the Tools menu, click Internet Options.

  3. Click the Advanced tab, and then locate the Security section.

  4. Uncheck Check for publisher's certificate revocation and then click OK.

  5. After the installation is complete, check Check for publisher's certificate revocation.


The Check for publisher's certificate revocation option is set on a per-account basis.
