  • Configuring Exchange Server 2013 Unified Messaging With 3CX and Not AsteriskNOW

    This article is an addendum to my blog series on configuring Exchange Server 2010 and Exchange Server 2013 with AsteriskNOW. AsteriskNOW is a easy to install version of Asterisk 1.8 in that it includes the underlying OS and the FreePBX software. The problem with Asterisk 1.8 is that it does not work well with the…

  • Building An Exchange Unified Messaging Lab (Part 8)

    In the extended series of blog posts we are looking at creating a unified messaging lab for Exchange Server. So far we have looked at installing a software PBX (AsteriskNOW) and configuring Exchange Server (both 2010 and 2013) to accept calls from our PBX. We have also looked and configuring our PBX to send and…

  • Building An Exchange Unified Messaging Lab (Part 7)

    In this series of blog posts I am looking at creating a Unified Messaging lab for Exchange Server 2010 (and 2013). Earlier posts have looked at the installation of the PBX (AsteriskNOW) and the configuration of the Exchange Server. This post will look at the configuration of the user’s settings. For each user there are…

  • Building An Exchange Unified Messaging Lab (Part 6)

    Earlier parts in this blog have talked about VoIP, configured AsteriskNOW software PBX and configured inbound and outbound calls via the PBX. Now it is time to configure voicemail to be provided by Exchange Server 2013 and for the telephone users to be able to call Exchange an listen to their voicemail. In addition to…

  • 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 2)

    This series of blog posts started with Part 1 where we discussed the requirements of the lab and what you would need from any PBX that you might have to hand. Part 2 (and the next few parts) will look at installing AsteriskNOW to provide a software PBX to support the Exchange Server unified messaging…

  • 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…

  • Building an Exchange Unified Messaging Lab

    This is a project I have been meaning to do for some time, and when I got around to doing it found it to be harder than I expected it to be. So this blog series covers the steps needed to build a Unified Messaging lab utilising Exchange Server 2010 and Microsoft Lync Server along…

  • Highly Available Geo Redundancy with Outbound Send Connectors in Exchange 2003 and Later

    This is something I’ve been meaning to write down for a while. I wrote an answer for this question to LinkedIn about a week ago and I’ve just emailed a MCM Exchange consultant with this – so here we go… If you configure a Send Connector (Exchange 2007 and 2010) or Exchange 2003 SMTP Connector…

  • 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

    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…

  • Office 365 Hybrid Coexistence and Edge Server

    One of the delights in my job is when Microsoft give me a call and ask me how something works in one of their products! Such a call came today and it involved get Office 365 hybrid coexistence working with an Edge Server. Exchange Server Deployment Assistant does not have the answer to this issue;…
