Exchange 2010 went GA:

Here's hoping for a solid release, especially considering all the new stuff in this one!

Exchange 2010 has just gone RTM:

I'm pretty excited about this release, especially with regards to clustering. Hopefully
the bits are solid and ready for production.

I am posting this in hopes that it helps other admins. We ran in to an issue that involved a huge increase in log generation on one of our storage groups. After running thru the usual suspects (virus scanning, looping mesages) we attempted to identify any potential users that could be causing the issue by using exmon. Most articles specify looking at the log bytes column for users
on E2k7 but for a mailbox on an E2k3 server, that column is non-functional. You can however use the BytesIn column to get an idea of any clients generating a lot of traffic to the server.

While exmon helped, it still did not definitively identify the user who was causing this issue. The next step was to use powershell to examine a subset of the logs being generated to idenitfy any patterns:

This ended up being the method that allowed us to identify a particular user that was causing an inordinate
amount of updates in the logs (apparently you need at least 50 logs files to get a good set of data). Going on a hunch from another case I had read about, we deleted this users OST file (he was running Outlook 2007/sp2) and the excessive log generation stopped. We are still waiting to hear from MS on whether their is a fix for this issue but at least we have a better method of identifying the problem user.

Here is a nice article on the new mailbox auditing features included in sp2 for Exchange 2007. This feature has been sorely missing as the in the box tools were basically useless and the 3rd party tools that we have looked at ended up causing more problems than they solved.

Also nice work adding a special hidden permission to allow you to exclude service accounts from the auditing as it makes looking at the logs much easier and helps conserve log space.

Microsoft just released SP2 for Exchange 2007 which is required if you are installing
Exchange 2010 in an existing environment. Be sure to test in your lab environment
before deploying to production servers.

SP2 for Office 2007 has been released and there are some major improvments with regards to Outlook performance, especially in cached mode. These were back ported to the Feb. cummulative update but are also included in SP2 along with other stuff.

Wow..... the high availabilty changes in Exchange 2010 are a game changer. If it all
works as well as described every Exchange shop in the world will be redundant after
adding a second server. I remember asking about mailbox replication at the MVP
summit a few years ago but they weren't there yet. I'm glad to see they kept on that
direction and hope this turns out to be a solid feature. Paul has a good rundown of the
details involved:

The first large scale review of Exchange 2010 is up (one of many) and it sounds like the
next version of Exchange might make up for all the sins 2007 did against the admins.  Only
time will tell...

Rollup 7 for E2k7/sp1 looks to be a turd as well as there are many reports of the update
failing during the installation process leaving the server in an unusable state. Apply with
A recent update to Outlook 2007 really helps speed up the app and allows for much larger cached mode mailbox support (MS claims 5gb now across most hardware should get good performance). This is a big change from the 1-2gb they used to recommend as a max when using cached mode. I've tested this patch on a few systems and it does seem to make performance improvements but time will tell if those improvements stay.

Well that was quick.... rollup 6 turned out to be a turd causing all kinds of issues. MS just
released rollup 7, hopefully it will be better!

Just an FYI..... if your trying to run jetstress on a Windows Server 2008 box and having
issues with it starting, try disabling UAC on the server. In my case this resolved the issue
although I haven't seen this documented anywhere.

Looks like the Mac is about to get a full featured Exchange 2007 client in the near future....
