I have a client who has an Exchange 2003 server and uses Entourage for the Mac. Last week all his sent items disappeared. It seems the problem is that Entourage’s local database corrupted and sync’ed back to the server that all these items where now deleted!

How To Speed Up Exchange Server Transport Logging
In Exchange 2010 SP1 and later any writing to the transport log files for activity logging (not the transaction logging on the mail.que database) is cached in RAM and written to disk every five minutes. In a lab environment you might be impacted by this as you might have sent an email and want to…

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 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).…

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…
