Building An Exchange Unified Messaging Lab (Part 4)
This blog post series is the steps to build a working unified messaging lab for Exchange Server. I thought I would write it all down as I found a lack of end to end documentation for the process and what I thought would be a days work turned into many as I worked at finding…

Building An Exchange Unified Messaging Lab (Part 3)
This blog is part of a series on creating a unified messaging lab for Microsoft Exchange Server. Configuring Unified Messaging was not as easy as I thought it would be and there was a lack of information that brought all the settings into one place, and a lot of incorrect information! The series started with…

Merge Exchange 2010 Personal Archive Back to Primary Mailbox
A feature of Exchange 2010 SP1 was to store “older” emails in a different database and to have that database on a cheaper storage subsystem. Given that Exchage primary mailboxes work very well on slower storage anyway you could well be in the position of needing to move archived content, that is content moved to…

Starting Exchange When You Have Active Directory Issues
I had a call the other day from a company who had Exchange issues. One investigation it turned out they had a very suspect Active Directory and no-one would admit to what they had actually done to get it in such a state! One server (DC1) would not talk to the other DC’s (Kerberos issues…

Domain Redirection and BPOS to Office 365 Migration
With Microsoft Exchange Online via BPOS (the precursor to Office 365) you were able to configure a simple CNAME redirection to make access to OWA easier for your users. For example, you could create a CNAME in DNS for mail.fabrikam.com (where fabrikam.com is your domain in BPOS) which pointed to go.domains.live.com and then when users…

Restricting Message Sizes in Exchange Server to Low Bandwidth Sites
Exchange Server has a series of different settings for controlling the maximum message size into and around an Exchange organization, but what about when parts of your organization have a considerably lower bandwidth than other parts, for example offices with servers in rural or hard to reach locations and require satellite WAN links or ships…

Fix Federation Trust Issues After Exchange Server Recovery
I had a need to recover an Exchange Server following a blue screen after patching that I could not undo. I had the databases intact, and of course Active Directory was installed on a different server so I installed a new server and ran setup /m:recoverserver (after installing all the updates and hotfixes that is).…

Hosting Exchange 2010 and Issues With Duplicate Contacts
When you are creating a hosted Exchange system using the Exchange 2010 On Premises product (not the /hosting version of the product) it is likely that if two or more of your customers create a mail contact in the global address list (GAL) for the same external email recipient they will see some issues with…

HTTPS Load Balancer Issues with Exchange 2010 SP2
When you install Service Pack 2 (and maybe SP1 too) on Exchange 2010 it resets the SSL flag on the root directory of the IIS website. You might have removed this setting for a number of reasons, mainly to do with having a HTTP to HTTPS redirect, but it can also be removed if you…

Shadow Redundancy Promotion Disabled After Exchange Server 2010 Service Pack 2
One of the new features added in Exchange Server 2010 Service Pack 1 was called Shadow Redundancy Promotion. Service Pack 1 creates a setting in EdgeTransport.exe.config to control the behaviour of this setting, and it defaults to a value of “False”, so that the feature is turned off. Enabling Shadow Redundancy Promotion is done by…

Exchange 2010 SP2 Prerequisites
To upgrade Exchange 2010 SP1 to SP2 requires the addition of an additional Windows server role that was not listed on the RTM and SP1 requirements. Therefore if you try an upgrade you will get errors about “IIS 6 WMI Compatibility” not being installed. To install this feature quickly on Windows Server 2008 R2, bring…

Exchange Log Truncation Failure in a DAG
Today I visited a client who had noticed that no log files had ever been removed after any backup within Exchange 2010 SP1. It was fortuitous that they had enough log disk space for about eight months of log generations. The disadvantage was that we were four months into this time period, so it was…

Exchange Server 2010 has a feature that tries to ensure that emails in transport cannot be lost. This feature is called Shadow Redundancy and lots of information on how it works can be found on the Internet. But what happens if a mailbox server or site is unavailable? Items will queue in a single location,…

How to Speed Up Hub Transport Server Selection
Install Exchange 2010 SP1! Installing the service pack fixes the round-robin selection process for remote hub transport servers in other sites (see Hub Transport Load Balancing) so that only the IP addresses of operational servers are used. Exchange 2010 runs on Windows 2008 (or 2008 R2) and this operating system supports IPv4 and IPv6. In…

Formatting Get-ExchangeDiagnosticInfo
For the last blog post for today, this one looks at formatting the output of Get-ExchangeDiagnosticInfo as the XML that this cmdlet returns can be quite long. For example if you want to see if your server is in backpressure then you need to view the output of the ResourceMonitor component, but as this contains…
