In a post from KC Lemson:
A few weeks ago, we asked you for your list of questions about E12 and said we'd pick a few and post answers on the one year anniversary of this blog, February 9th. Well as you can see, I totally missed that date :-) Very sorry about that and I'd be happy to list off my excuses, but let's get on to the good news instead: for the foreseeable future, we are going to have a monthly post about E12, the content will usually be based on the questions we get from you. So without further ado, here are answers to the first set of questions. Please add any additional questions as comments on the E12-focused posts and they'll be added to the list for consideration for answering the next time around. We won't be able to answer everything, depending on the state of the feature in question, as we only want to talk to you about features that are very baked. Without further ado:
Question #1: Lots of people asked about the 32k rules limitation: "As someone else mentioned how about improvements to server side rules (32k limit)", "Since I ask this every time I talk to Microsoft developers :), any news on when will the 32k server side rule limitation be resolved".
Answer #1: I'm happy that I get to be the one to tell you that the 32k rules limit is gone... It's now 64k! Just kidding!! We are still determining what the default will be (there's a tradeoff in performance of course, the more processing you ask the server to do on inbound mail, so we want to choose a smart default), but the administrator will be able to change the limit.
Question #2: I'd like to see a unified messaging function in E12 (facsimile, voice,...).
Answer #2: UM is absolutely an area we are investing in, as you can see from some of the articles about it, such as this one from eWeek. If you call me at Microsoft today and leave me a voicemail, it gets routed to my inbox using only Microsoft technology.
That's it for right now, and look for a post next month with some more questions and answers about E12.
