Agree with these comments:
* Add the ability to manage Exchange functions back into ADUC. It's hard to tell support that they have to go back to two utilities to do their jobs. <note: I understand why you made a separate tool, to separate admin functions, but why does a separate tool have to preclude the use of an integrated too, too?>
* The ability to see mailbox sizes in the GUI view of recipients, or store database sizes would be good too. Anything to help me balance several CCR clusters is helpful.
* An easier to learn message tracking system. Oh how I long for Ex2k3 message tracking. I know, I'm just not use to it yet.
* The cert process is ridiculous- even the example you posted had syntax errors. If you can't get it right, how in the world can a jack-of-all-trades, overworked admin?
My two biggest frustrations are:
1. That you opted to build out Powershell/EMS completely while also choosing to remove critical parts of the GUI. It's fine to add features (like EMS), but doing so at the expense of features that we've used for years is a BAD idea. Many admins are now collecting EMS commands in notepad files. Is this really a step forward? Imagine of the Office team decided it was too complicted to code the Print function into Word 2007 and just had users enter a Powershell command to print documents...
2. Even with SP1 installed, there seems to be a massive memory leak, at least in a single-server environment. I'm waiting on hold with PSS to get this sorted out right now (and yes, I have the aforementioned hotfix installed).
3. The install scripts were not prepared well at all. For example, the single label domain issue should have been caught at install, and the hoops I had to go through to get SP1 installed were nothing short of atrocious: Every time the install failed a complete reboot was required and once when it failed it left many services set to disabled.
I've been using Exchange since 5.5 and this version isBY FAR the most unstable, difficult to admin, buggy version, and we're over a year out from RTM now. Are the problems and feature gaps ever going to get fixed, or will this be like Vista: The version everyone tries to avoid while waiting for the next one?
