Microsoft announces Exchange “14”

Nice one! Microsoft announced the existence of Exchange 14 (the successor to Exchange 2007) today. With Lotusphere on the horizon, I’m sure it’s just a coincidence. My home domain is hosted on Exchange 14 through Exchange Labs, and I’ve been working with it quite a bit for a number of projects. There are some very exciting things in it, and I’m looking forward to being able to talk about it more.

Extremely detailed summary of what’s new in Exchange

Wow. Rob Sealock, a technical account manager at Microsoft, posted an incredibly detailed list of Exchange fixes and updates for the month of December. I sure hope he keeps these posts up.

Entourage to get Exchange Web Services support

Great news from Microsoft’s Mac Business Unit: they’ll be releasing a version of Entourage that uses Exchange Web Services. This is great news because WebDAV, the protocol that previous versions of Entourage have used, doesn’t provide full support for every type of Exchange data item. The Exchange Web Services (EWS) version of Entourage will support full synchronization of tasks, notes, and categories with servers running Exchange Server 2007 SP1 or later. This should please some of the folks who have been lamenting the lack of Exchange sync functionality in Entourage. The best part: they’ll release this as a free update to Entourage later this year.

Cutting off e-mail for former employees

Say you’ve fired someone, or laid them off, or sadly waved goodbye as they left of their own volition. How can you effectively prevent them from accessing your Exchange servers once they’re gone?

Most connections to an Exchange server are persistent, in the sense that once the client’s authenticated the connection will remain open. This allows the client to continue to send and receive mail… the exact opposite of what you want. You might think that disabling the Active Directory account for the user would do the trick, and it will indeed prevent other logons from succeeding. However, for about two hours, existing logons will continue to work. Here’s what to do to instead:

  1. Disable the user’s mailbox. This prevents new logons to the mailbox.
  2. Set the Send Prohibit quota to 0. This prevents the user from sending new mail; the quota change takes effect immediately.
  3. Move the user’s mailbox to another database. This will immediately disconnect all open mailbox connections from any client.

Voilà! Problem solved. (Hat tip: Scott Schnoll)
