Background
• A lot of the background information is
captured in an internal wiki:
http://zed.cisco.com/confluence/display/U
CBU/Exchange+2010+Investigation
• Note that there are “children” pages off
the main Ex2010 wiki. They contain
important information too.
• Please follow the installation instruction.
This TOI is not going to repeat that.

CAS – Client Access Server
• All MAPI traffic goes through the CAS
when dealing with 2010 mailboxes.
• It is very important to install a CAS first
before any other role. Otherwise mailbox
access, even through Outlook, will fail.

CAS – Client Access Server
• To check if a mailbox database has CAS
set correctly, run the following in
Exchange Management Shell (EMS):
[PS] C:\>Get-MailboxDatabase
Name
Server

CAS – Client Access Server
• If RpcClientAccessServer does not point
to the correct CAS, issue the following
command in EMS:
Set-MailboxDatabase <Mailbox Database name> -RpcClientAccessServer <name of the CAS server>
For example:
Set-MailboxDatabase "Mailbox Database 1952193598" -RpcClientAccessServer SIB-E2K10-C.SIB.ECSBU-LABSEA.CISCO.COM

DAG – Database Availability Group
• Unity works with Exchange 2010 DAG.
However there is currently one limitation.
When there is a DAG switch over, Unity
could take up to 15 minutes (default GC
sync interval) to detect that. During this
period, Unity will be in UMR mode.

Throttling Policy
• Exchange 2010 enforces a throttling
policy. Unity must has this throttling
policy set to unlimited. To do that, follow
the instruction on this wiki page. (This
should be covered in the installation doc
as well.)

Script to check Throttling Policy
• We have created a PowerShell script to
check if an acceptable throttling policy
has been applied to the Unity messaging
account (typically named
“UnityMsgStoreSvc”).
• This script can be downloaded from the
same place where you downloaded this
TOI. We are also planning to including this
script into CommServer\TechTools.

Running the script
[PS] S:\wfu\Ex2010>.\umsg.throttle.check.ps1
Enter the name of the Cisco Unity Messaging Services Account
==>: UnityMsgSvc
Account Name: Unity MsgSvc
[CN=Unity MsgSvc,CN=Users,DC=SIB,DC=ECSBU-LAB-SEA,DC=CISCO,DC=COM]
RecipientType: UserMailbox
ExchangeVersion: 0.10 (14.0.100.0)
Unity MsgSvc is assigned to ThrottlingPolicy "Unity Exchange 2010 Policy".
RCAMaxConcurrency value for Unity Exchange 2010 Policy is null (unlimited).
This account is acceptable for use as the Cisco Unity Messaging Services account when Unity subscriber mailboxes are hom
ed on Exchange 2010.

Permission Permission Permission
• It is important to run the updated PW to
grant Unity access to the Exchange 2010
mailbox database.
• After the initial installation of Exchange
2010 support, when new mailbox database
is added, make sure to run PW again.

New mailbox database
• When new mailbox database is added in
Exchange, make sure to run PW.
• Also reboot Unity after a new mailbox
database is added. These are not new, but
worth to watch out for.

11
MAPI DLLs
• When working with Exchange 2010, it is
important to make sure that the correct set of
MAPI DLLs are installed on the Unity box. If you
follow the installation instruction, you should be
OK. But to double check:
• Make sure there is no emsabp32.dll and
emsmdb32.dll in windows\system32 directory.
• Windows\system32\mapi32.dll should be at
version of 6.5.7654.9 or higher. Or still at version
1.x. Anything in between is no good.

12
Misc
• UDP-Push Notification mechanism isn’t
used any more with 2010 mailboxes;
async RPC (slow RPC poll) is now used.
