Creating a dedicated backup-network for Exchange DAG

DAG is a very useful technology, we can all agree on that. It is, in fact, so simple and useful that I’d say that everyone who can afford an extra Exchange-server license and storage, should use it. And that is, frankly, pretty much everyone. Best case scenario, you have nodes on completely separate hardware and cover both database, server and storage failure; worst case you’re on the same virtualized host and cover database failure. Either […]

Enabling impersonation in Exchange 2010

There are a bajillion blogs about this, but there’s also alot of wishy-washy stuff around it. So I figured it might be worthwhile condensing it all down to what you really want to know. The scenario is this: You have an application (in this case Dynamics CRM), which connects to EWS and wants to use a service user to interact with mailboxes. In 2007 you’d have to grant rights; but that is, frankly awful to […]

Exchange 2013 CU2 released

Good news everyone! CU2 for Exchange 2013 is out; and it brings back many of the features that where missing from CU1/RTM; but where there in 2010. Deets are here: http://blogs.technet.com/b/exchange/archive/2013/07/09/released-exchange-server-2013-rtm-cumulative-update-2.aspx Highlights are the fact that all CUs are now full installs; and new servers need not be patched, but deployed using the CU-installer. Which means bigger DL; but easier install, and less hassle. Also: Support for 100 databases in Enterprise, up from 50 in […]

Credential prompts in Outlook / Exchange 2013 & 2010 – Updated!

Coexistence between Exchange 2010 and 2013 is fairly new still; so a few bugs is to be expected. This is however a rather large one. Credential prompts in Outlook (I’ve seen this in both 2010 and 2013) is usually an indicator of authentication/virtual directory configuration errors.   What I’ve seen a few times now is that if you have this scenario: User mailbox is on Exchange 2013 User accesses resoruces (public folders or shared mailbox) […]

Setting up single namespace in Exchange 2013

One of the great changes in Exchange 2013 is the simplification of namespaces. Where you in previous versions needed a handful, you can now stick with two. Well, you CAN do it with one actually. The documentation on this is a huge ball of misconceptions and old best practices, so I decided it’ll be worth doing a simple tutorial on how to set it up. Once you know how to do it, it actually is fairly simple. […]

Installing Exchange 2013 CU1 in co-existence

A simple walkthrough of the install of  Exchange 2013 CU1 in a Exchange 2010 environment. This is based on a clean server 2012 install. Just to emphasize one thing first: CAS-arrays are out. CAS in 2013 is just a simple proxy to redirect to the correct user mailbox, so they are no longer needed. Download CU1 from http://www.microsoft.com/en-us/download/details.aspx?id=38176, and extract. Download and install the Microsoft Unified Communications Managed API 4.0, Core Runtime 64-bit from http://go.microsoft.com/fwlink/?LinkId=260990 Download and install […]

Exchange 2013 CU1 released!

Finally! This one has been long in the wait. CU1 enables co-existence with older versions of Exchange (2007/2010), which to be honest most have. Released just now; so not much experience with it so far, but part of the delay has been due to extensive testing, so I imagine it’s all good. Details on the Exchange team blog: http://blogs.technet.com/b/exchange/archive/2013/04/02/released-exchange-server-2013-rtm-cumulative-update-1.aspx And of course the download: http://www.microsoft.com/en-us/download/details.aspx?id=38176 This is a 1.3GB download, so I imagine this is […]

Event ID 36888 – Schannel

I stumble upon this all the time. It’s logged as an error, and it usually comes in bunches, looking like this:   So what to do about this. What is it? Well, nothing. It’s a false alert if there ever was one. It’s basically saying that someone tried to access a website (Exchange website in this case) using an unsecure connection, when a secure connection is required. Http instead of https usually. I did spend […]

0x80200049 Offline Address Book-error

This totally stumped me for a while. I had a few random users getting an 0x80200049 error when downloading the offline address book. I went over everything on Exchange (2010) and everything looked fine and dandy. Even tried resetting the Outlook profile, to no avail. Well, lo and behold; Outlook uses BITS to download the OAB; and if the BITS queue goes full (60 jobs I think), it stops. Intuitive, right. No mention of BITS anywhere, […]

Exchange ActiveSync features

So I stumbled upon this handy chart: http://en.wikipedia.org/wiki/Comparison_of_Exchange_ActiveSync_Clients Which cured my head-scratching over why I couldn’t see a recovery password for certain devices. Not all Active Sync clients support it. In fact, most don’t. Could be useful to keep in mind when deciding company policy.
