Problem 6

Intro: Successfully joined the core WAE to the active directory. Verified both Core and Edge WAE for optimization with the command "accelerator mapi verify encryption-settings". Seeing that some connections are correctly being optimized (See below). Would be nice if someone could bring some light into what Unknown Context means and how to deal with this. Let me know if I can provide more information.

Environment: Exchange 2010, WAAS Version: 5.3.1

Issue: Some Connections are being optimized and some are not. Note: Times might not be the same everywhere because the test was repeated several times and the log file outputs where taken at different times (but checked and are the same).

Here seems to be the root cause as we don't receive a context.

The connetions that work receive a context.

Authentication does not work, but this is the edge WAE so i guess this should not be the root cause.
