We are in a mixed mode environment where we have Exchange 2003 as the partner exchange server. we also would like to plan on migrating mailboxes over to 2010. we applied ES35 and all the necessary patces and server updates, however, when users on 2010 access their mailbox via TUI, they get a failsafe message saying "your messages are not available now".
Unity event viewer generates a log with:
Event Type: Error
Event Source: CiscoUnity_MALEx
Event Category: Error
Event ID: 30007
An error occurred while AvCsMgr tried to logon to MAPI mailbox
/o=KILROY/ou=ElSegundo/cn=Recipients/cn=(name of users)on server KRCWMCDAG1.
The MAPI subsystem return the following error: The information store
could not be opened..
I opened a TAC case and they saw bugs related to this only when 2010 was the partner exchange. we decided not to pursue further.
is there a workaround to get this working or when will Cisco have a patch to get this fixed.
