Title
Mail agent is taking significant time when logging in and processing mail data -
Description
In the log of a mail agent the following can be observed:9/13/2011 3:49:25 PM CSession::Logon TraceMsg 4800 Logging on to the mailbox 'LEDN of the user' (Server: 'name', user: 'exch
\admin', has assocciated PFDB: 'True', connection flags = 0).
9/13/2011 3:49:25 PM CaeMAPISession::Logon TraceMsg 0 Trying to synchronize MAPI profile creation.and then, after 15 or 20 minutes, the agent will proceed with:9/13/2011 3:58:09 PM CBaseApp::Init Informational 4700 Migration Manager for Exchange Mail ... Agent (ver. 8.8.0.194) has been
started on server 'Servername'. -
Cause
This applies only to QMM 8.8 and to a situation where multiple mail sync agents are employed on the same agent host machine.When working on a computer the agent needs to create a MAPI profile. Such profiles are created on the OS level and only one profile can becreated at time. If two profiles are being created simultaneously them the MAPI will error out and start malfunctioning.
In order to avoid any issues the agent, when creating a profile, is setting a so called "mutex", this happens on the OS level. The secondagent is waiting and once a profile is created and the mutex is released the second agent will lock the mutex and will create a profile, andso on.

Resolution
There is no real workaround. If this is causing serious inconvenience then one might consider to place the agents of different computers
(agent hosts).
