Need to deploy Exchange 2010 with all roles HUB, CAS and Mailbox to be load balanced. Currently deploying DAG with two members.

Suggestion to deploy all roles redundancy:

To load balance CAS you need to use Windows Network load balancing or Hardware load balancer. If you are also deploying DAG along with load balance CAS then it is recommended to install mailbox and CAS server role on different machines or servers. Because DAG uses Windows Failover Clustering which cant co-exist with Network Load balancer Or you can use Hardware Load balancer.

You could refer below article for regarding Load balancing in Exchange 2010

When try to uninstall exchange 2007 get error

“Uninstall cannot continue.  Database “Public Folder Database”: The public folder database “SERVER\Second Storage Group\Public Folder Database” contains folder replicas…

Solution:

Run the Get-PublicFolderStatistics cmdlet using the Exchange Management Shell and check the output. If the folders listed are of no use then you can pipe this command with Remove-PublicFolder

Get-PublicFolderStatistics | Remove-PublicFolder

Once done, confirm there is no folders or no results by running same Get-PublicFolderStatistics cmdlet

Refer below article for further clarification

Clarifying the public folder store removal on Exchange Server 2007

Moving from Exchange 2003 to 2010. When use Public folder Management Console in EMC 2010 to perform Public Folder move, it errors saying

“Multiple MAPI public folder trees were found”

These are the first few steps.

1. In the Console tree, click Toolbox.

2. In the Result pane, double-click Public Folder Management Console. The Public Folder Management Console appears.

3. In the public folder tree, click or expand Default Public Folders, and then select the parent public folder of the public folder that you want to move to Exchange 2010. This is where I get the error.

Could see Public folder under Exchange Administrative Group in ESM on 2003 server but on 2010 it errors out. No event generated on either of the Exchange server.

Solution:

The Smart Host impacts Public Folder replication.This setting is found in Exchange 2003 System Manager under:

Administrative Groups > ‘Exchange 2003 Administrative Group’ > Servers > SERVERNAME > Protocols > SMTP > Default SMTP Virtual Server (Properties) > Delivery tab > Advanced Button > “Smart Host” field.

A smarthost specified here will break public folder replication with Exchange 2007/2010.

Generally you should not use a smarthost at this level.  In order to have your outbound internet email sent to a smarthost you can set that under Routing Groups and then properties of whatever the name of your internet connector is.

Someone restored backup to Exchange 2003 Datastore. The mailbox once logged in merges all the changes from restored data into the local .ost file with no emails missing.

Later users complained that there mails missing in the shared mailbox accessed through Outlook.

This seems like .ost file doesn’t merge the data not belonging to its own mailbox/ of another mailbox. Could be let me know resolution as how to merge the shared mailbox data into user’s mailboxes.

Solution:

For OST file recovery in disaster scenario is to login to the user mailbox in offline mode and extract ost file into pst file and then copy that data again from PST file to recovered mailbox after logging as online mode.

We have stretched across two sites, primary and DR. Wan link is 150Mbps and we have encountered some network issue. We are planning to rate limit/ policy on traffic destined to DR site to 100Mbps. Not aware as will the packets be dropped after reaching the limit of 100Mbps.

Ans: Exchange would do is just throttle back and queue up the replication traffic.   So, at worst, your D/R site would just get behind on replication.

Need to build a DAG with 2 mailbox servers. Need a guidance in doing this. What test need to be performed to be sure that everything works well

Ans: As you Enterprise edition you can configure your mailbox servers into a DAG. For further details you can follow below article:

We have exchange 2007 in 2008 windows root domain. I removed a child domain from the forest and now cannot view the mailboxes of the users belonging to that child domain.

Moved one user AD account to another OU and since then he isn’t able to use activesync on his phone. When checked his ‘manage mobile device’ in EMC it gives error

http://209.85.62.24/365/183/0/p408925/r.jpg and in EMS as oops.. will replace it later.

Ans: The error message just indicates a process that didn’t finish correctly. Click “Refresh” from the EMC and then click on Manage mobile device

OR

Try to reconnect the user mailbox with the AD account:

1. Open EMC, expand to recipient configuration, right click the user and choose disable.

2. In Disconnected mailbox, right click the disconnected mailbox and choose connect. If the disconnected mailbox does not appear, right click “Disconnected mailbox” and choose “Connect to server”. Select the mailbox server which hosting this user’s mailbox.

3. When reaching the Connect mailbox page, click “Existing user”, then select this user’s account
