IMF and the Junk E-mail folder in Outlook

I’ve posted several IMF-related blog postings in the past — here, here, and here. In these posts, I’ve focused mainly on the gateway behavior of the IMF. This is because that’s really what the IMF is, of course… just the gateway behavior. But when your mailbox server is running Exchange 2003 or better, there’s a whole…


Trouble Upgrading your Exchange 2003 Cluster to SP1?

Note: This information is now available as a public KB article: KB.867624 Some folks on the newsgroups are having difficulty getting their Exchange 2003 clusters upgraded to Exchange 2003 SP1. One example of an error that’s been reported: Not able to upgrade the EVS because of error c1037b44:”Version of Exchange on this machine does not…


Exchange Special Mailboxes Part 1 – System Mailbox

Every now and then, people ask about one (or all) of the system-related mailboxes on Exchange 2003 servers. There are actually three in particular that people frequently notice and confuse: SystemMailbox{guid}, System Attendant Mailbox, and SMTP (servername-{guid}) Mailbox. There are a bunch of common questions, which I will try to address in the next few…


Interesting Issue: E2k3 Cluster setup.exe prompts for 5.5 Site credentials

Exchange 200x clusters install in two separate phases: In the first phase, the administrator runs SETUP.EXE on the CD. The Exchange binaries are copied from the CD to the local harddrive, some IIS bindings are created, miscellaneous local-to-the-node stuff happens. A number of things are read from the AD, but little (if anything) is actually…


Exchange Special Mailboxes Part 2 – System Attendant mailbox

This post is a follow-on post to the SystemMailbox post from last week. Here I’m talking about System Attendant mailbox in Exchange 200x.   System Attendant mailbox What is it and what is it used for?   Each Exchange 200x server has one (and hopefully only one) System Attendant mailbox. If the server has a…


Hooray for Eastern Standard Time!

Well, I’m back from vacation and thanks to this morning’s time change (at least in the US), very glad to be back into Eastern Standard Time! Warning: Timezone misunderstandings are a huge pet peeve of mine. Ask my friends. 🙂  This is the easy part of the year — the half of the year where no matter…


Do I really need to upgrade my filters?

After posting the Exchange 2007 OPATH intro and How to Upgrade the Filters posts to EHLO over the past few days, one question that’s come up enough to warrant another blog post is “Do I really need to upgrade my filters”. And the answer is pretty straight forward: maybe. Ok, that’s not fair. Let me…


MSDTC and Exchange clusters

Over the years, the best practice recommendations on where to place the MS Distributed Transaction Coordinator (MSDTC) resource in Exchange cluster has bounced between two differing views. One camp thought it was unadvisable to place this resource in the cluster group occupied by the quorum resource, while others noted that Exchange doesn’t really use DTC…


Filterable Properties in Exchange 2007 RTM

Since I’ve posted a number of times about OPATH filters for Exchange 2007 and RecipientFilter parameter for EAP/AL/GAL/DDG objects, it’s only fair that I get a lot of email asking me questions about how to use it, how to convert old-style LDAP filters to OPATH, and what are the filterable properties that can be used….


Badmail changes in Exchange 2003 SP1

Prior to Exchange 2003 SP1, if your SMTP protocol virtual server didn’t have anywhere to go with a timed-out email, it would drop it in the BadMail directory on your server. This directory could potentially grow and grow without bounds until it filled up the disk, etc. There are two big changes to Badmail in…
