Something a little different this week – two mini-posts!

One today on a Lync Server update. One tomorrow on the Jabra BIZ 620 Duo USB headset.

Mobile Clients are Coming Soon: Prepare Lync Server

Yesterday I tweeted a link to a recent Microsoft announcement: Lync clients coming soon for Windows Phone 7, the iOS platform, and Android (via Engadget).

Last week, Microsoft also released a new Cumulative Update for Lync Server 2010 – one intended to prepare Lync for use of these new mobile clients.

The update, Cumulative Update 4, consists of multiple server-side (and client-side) updates, as well as six new Cmdlets. The cmdlets are what mark this as a mobility update. Tom Arbuthnot has written thorough descriptions of the cmdlets over at the Lync’d Up blog. I’ll just give overviews on what they do here (go read his post for full information – it’s worth it!).

  1. CsAutodiscoverConfiguration: Lets you change Autodiscover settings. Autodiscover helps client apps (like a mobile Lync client) find certain resources, like a user pool.
  2. New-CsWebLink: Creates a Web link to Autodiscover. Handy for updating configuration with new clients.
  3. Test-CsMcxPushNotification: Verifies that Push Notification’s working, so you’re able to send notifications out to mobile devices.
  4. CsMobilityPolicy: Lets you control Mobility Policies. In Lync, these policies govern who can use a mobile client, as well as if you can use Call via Work (using work numbers instead of mobile numbers for calls).
  5. CsMcxConfiguration: Configures Lync Server Mobility Service settings. Enabling mobile devices to use many of Lync’s services – Presence information, voicemails, conferencing, etc.
  6. CsPushNotificationConfiguration: This cmdlet lets you configure Push Notification.

Lync Server Updates for Core Components, Administration and Clients: Install Them All

The Cumulative Update 4 files are available for download at Microsoft Downloads. The easiest installation method would be to use the Cumulative Update Installer (LyncServerUpdateInstaller.exe).

If that doesn’t work for you, look under “Installation Methods” on this Microsoft Support page for a manual install option.

And as Justin Morris wisely reminds us – don’t forget to backup your Lync Server setup first!

Check back tomorrow for our second Lync headset review!

    Has anyone noticed that after applying the latest lync updates to your edge servers you can now login with any user without a password? This started happening in our test environment after applying the update. I have checked with one of my peers who also runs a lync environment and he is having the same issue. He did not notice it until I pointed it out. You still have to type in a password for your director and front end pools. This is happening on our edge pool.

    That is pretty curious, Brad. I don”t think we”ve encountered that yet. I”ll check with our engineers though; sounds like a potential security hole if it isn”t addressed before going live. Thanks for bringing it up!
