Everything About Microsoft Exchange Server

Microsoft Exchange Server

What is Microsoft Exchange Server?

Microsoft’s calendaring, email, scheduling, contact, and collaboration platforms are all Microsoft Exchange Server.

The primary purpose of the Exchange service is to adopt and give access to the users who can message from mobile phones, web-based systems, and desktops. The Exchange Server has telephony capabilities that support voice messages.

Features like Security and storage help the organization achieve content, executive compliance tasks, and perform searches.

Microsoft Exchange Server

The working of Exchange Server

Exchange Server is an enterprise-class collaboration product whose primary focus is sending, storing, and receiving email messages. It also provides several collaboration features like calendaring; it has tight interaction with other Microsoft applications.

Features of Exchange Server 2019

The salient features of the Exchange Server of 2019 provide significant fast, more reliable failures between servers. It was made to improve overall performance and the advantage of solid-state drives, including larger disks and also the latest storage hardware.

Some of the main features are

  • It provides support up to 48 CPU cores and 256GB of memory
  • On the Windows server, it enables installations.
  • It prevents forwarding the meeting invitations by the attendees.
  • With additional out-of-office options, it provides end-users.
  • It also enables administrators to assign permission to others.
  • It also has a feature where it allows the administrators to cancel the meetings even if the organizer left the company.

Requirements for 2019 Exchange Server

  • Even in Active Directory (AD) forests, Exchange 2019 can be installed with the existing Exchange 2016 and 2013 servers. Before this, no earlier versions had the feature to install the same as in 2019.
  • There must be at least Windows server 2012 R2 or higher AD forest function level.
  • Must use the 64-bit processor for the Server hosting Exchange 2019.
  • The Server should have between 128 and 256 GB of RAM
  • All disk partitions which are containing the system partition require New Technology File System(NTFS).

Database availability groups

The available database groups are an Exchange subsystem which ensures HA. It was first introduced in 2010 (Exchange 2010), and within no time, it became one of the most critical subsystems within exchanges.

Database Availability Group is not based on technology specifically made for the Exchange team alone but based on Windows Clustering. This means that the features and bugs that are in the Windows server can also make a significant impact on how Exchange functions.

Can’t Connect Outlook 2003 To Exchange 2010. Unable To Open Your Default E-mail Folders

E-mail Folders

I was trying to connect to my Exchange 2010 RC Server with Outlook 2003, but couldn’t connect successfully. I tried with Outlook 2007 & 2010 and was able to connect successfully. That made me search whether Outlook 2003 is a supported client and it is. The error message is “Unable to open your default e-mail folders”

After playing around for a while, I found the solution. Before I jump in to the fix, let me explain a few changes in Exchange 2010 in terms of MAPI connectivity.

All MAPI clients connecting to Exchange 2010 server connects to the mailbox through the CAS Server.
A new service named Exchange RPC Client Access is introduced in 2010 CAS which handles all MAPI connections.
All MAPI clients connect to the mailbox server directly in Exchange 2007.

We can see that this service needs rpc encryption and it is set to True by default.
Same is the case with Outlook 2007 & 2010 profiles! Encryption between Outlook and Exchange is enabled by default, which explains why these clients can connect to Exchange 2010 without any issues.
Outlook 2003 profiles don’t enable encryption by default.

Once I checked the box, I could connect to my 2010 mailbox.
You can also disable the requirement of 2010 CAS servers to have encryption enabled by running Set-RpcClientAccess –server servername –EncryptionRequired $false. This is not recommended though!
If you have too many Outlook 2003 clients trying to connect to a 2010 server, you can enable encryption using Group Policy.

Connection Filtering In Exchange 2013

Connection Filtering

The change in Exchange 2013 architecture with just two roles has had an effect on the connection filtering anti-spam agent.

John asked via email – “How can I implement connection filtering in Exchange 2013 now that FPE 2010 is discontinued? I was able to install the anti-spam agents on a 2010 hub server & the connection filtering was taken care of”.

In Exchange 2013, the anti-spam agents can only be installed on the Mailbox role. But, the connection filtering which is very useful in fighting spam emails is not available in 2013. Same goes for the attachment filter. Even though CAS proxies emails back and forth (if setup correctly), it is a stateless proxy and can’t have any anti-spam agents on it.

As there is no Edge role in 2013 yet, the workaround is to use a 2007 or 2010 Edge role with the Exchange 2013 infrastructure. Both versions of Edge server can perform connection filtering. One point to note is that the edge subscription is setup from the Mailbox role in 2013 compared to the hub in 2010.

Another option to have connection filtering will be to use a cloud based anti-spam offering like FOPE or Exchange Online Protection (EOP) as it is called these days.

Message Moderation Is Not Working In 2007 & 2010 Mixed Organization

Message Moderation is a new feature in Exchange 2010, which establishes an approval process for email delivery (especially for distribution groups). Check one of my previous articles for more info.

I came across a problem in an exchange environment which has both 2007 and 2010 transport servers. There were few distribution groups for which message moderation was enabled and it wasn’t working as expected.

The problem was that the emails to the distribution groups were picked up by a 2007 transport server and hence message moderation wasn’t working. Why? Message moderation is a new feature of 2010 transport server and it is not supported by 2007 counterparts.

Hence what can we do to make sure that moderation works in a mixed environment? The trick is to set a 2010 transport server as the “Expansion Server” for the distribution group. To do that, take the properties of the group and navigate to “Advanced” tab. Check the option “Set Expansion Server” and select a 2010 server.

Lagged Database Copies In Exchange 2010 DAG

Lagged Database

The concept of lagged database copies was introduced in Exchange 2007, implemented using Standby Continuous Replication (SCR). With SCR, we can delay the time when the logs have to be replayed to the SCR target. There is also the option of specifying truncation lag time, the option which allows us to delay the time before the log files are truncated. The maximum lag time for both the options is 7 days in Exchange 2007.

With Exchange 2010 DAG, the lag time for both replaying and deleting the logs have been increased to 14 days. This is good if your company wants to go backup-less. Of course, the company has to be aware of the risk of going without backups, as lagged database copies can’t be a solution for all recovery/restore issues.

The two parameters you need to know are ReplayLagTime and TruncationLagTime. The ReplayLagtime parameter specifies the amount of time that the Exchange Replication Service should wait before replaying log files that have been copied to the database copy location. The format for this parameter is Days.Hours:Minutes:Seconds. The default value is zero seconds.

The TruncationLagTime parameter specifies the amount of time that Exchange Replication Service should wait before truncating the log files that have replayed into a database copy. The time period begins after the log has been successfully replayed into the database copy. The format for this parameter is Days.Hours:Minutes:Seconds.

The lag times can be configured either while setting up the database copy (Add-MailboxDatabaseCopy) or after setting up (Set-MailboxDatabaseCopy).

Archive Mailbox In Exchange 2010

Archive Mailbox

Archive Mailbox is one of the many welcoming features in Exchange 2010 Server. This feature solves issues related to PST files which gives headache for any exchange admins.

Let me explain how archive mailbox feature will address the existing problems.

  • There is no company which doesn’t have staff using PST files. Archive mailbox gets rid of PST files by giving the user an additional mailbox.
  • PST files are local to the user’s machine, gets corrupted easily and is hard to include the files in backup. Archive mailbox sits in the same mailbox database as the user’s main mailbox and can be included in the backup easily.
  • Archive Mailbox is available in Outlook as well as Outlook Web App (OWA), which is a huge improvement. Users can access their email archive irrespective of where they are.
  • Archive Mailbox is included as part of the Exchange Enterprise CALs and hence no extra cost is required (for those who have ECALs).
  • Retention policies can be set for emails/folders in the archive mailbox.
  • User has the option to search for emails in archive only or both primary & archive mailbox.
  • Archive Quota can be set separate to the primary mailbox.
  • Emails in existing PSTs can be dragged into the archive mailbox very easily.
  • Users get Conversation View scoped to archive mailbox as well.
  • The archive and primary mailbox share the same user account.
  • Only one archive mailbox can be configured for a user.
  • Archive mailbox gets created on the same mailbox database as the primary one, which is a drawback. Future service packs might bring the option to create the archive mailbox in a different database.
  • The default quota warning for the archive mailbox is 10GB, which can be changed.
  • All in all, it is good news for admins as they don’t have to worry about issues like a lost laptop with PST files in it, corrupted PSTs etc.
