  • Open the menu next to your display name, and click Options.
  • In the left column, choose Connection.
  • At Connection settings, click the button Advanced settings.
  • Delete the SOCKS entries.

• If you are using Windows Vista, disable the auto-tuning feature.
  • Click Start, All Programs, Accessories.
  • Right-click the entry Command Prompt, and choose Run as administrator.
  • When Windows prompts for your consent, click Continue.
  • Now enter the following line in the command prompt, and press Enter:
    netsh interface tcp set global autotuninglevel=disabled
  • Note: using this command, you are disabling the Windows auto-tuning feature.
  • Now retry to sign in to Messenger.
  • If it still doesn’t work, re-enable the auto-tuning feature by repeating the preceding steps, yet typing this line instead:
    netsh interface tcp set global autotuninglevel=normal
• If you are using Windows Vista and a router (e.g. made by Linksys, Netgear, D-Link) to connect to the Internet, visit your manufacturer’s website to check for updates to your router’s firmware.

When you delete or block a contact person, Messenger will try to synchronize your local contact list with the server, and this connection cannot be established properly on some organizational environments.

• Solution 1: Add Messenger servers to exception list
  1. Click Start, Control Panel, Internet options.
  2. Switch to the Zones tab.
  3. Mark the entry Trusted sites, and click the Sites… button.
  4. Add the following entry to the list of trusted sites:
     https://*.contacts.msn.com
  5. Click OK, and switch to the Connections tab.
  6. Click the LAN settings button. If the Advanced button is active, click it and add *.contacts.msn.com to the Exceptions list.
  7. Click OK to close the dialogs.
  8. Retry to sign in to Messenger.

• Solution 2: Choose a different place where to synchronize your contact list
  1. Take your notebook home and connect to your private Internet.
  2. Sign in to Windows Live Messenger.
  3. It will synchronize the contact lists.
  4. Now, Messenger will also sign in at your corporate intranet, as long as you do not change your contact people.
• Solution 3: Switch back to Messenger 2008
  • The last resort is to uninstall Messenger 2009 and start using Messenger 2008 (8.5) again.
    Update 15 September 2009: Since Messenger 2008 does not work anymore, you will have to contact the Messenger support (see below).

I might be wrong, but to me it’s another ‘company’ trying to make something never thought of before, that isn’t going to make it, and it doesn’t looks secure at all. I don’t see Opera Unite getting anywhere.

I mean, Opera is used by 1 to 3% of all the people online? And they really think that they can pull this off? More importantly, with that small sized company with no serious skills will be able to secure files etc? It’s just one big joke.

Today, Lawrence Eng, product analyst at Opera, talks about some details on what Opera Unite is designed for, why it was invented, and what it is not.

We don’t hate social networks and big-server computing. The point I tried to convey is that users should have a choice–freedom to decide how and where their data resides and is used. In some circumstances, they may choose Facebook or Flickr, but in other (equally legitimate) circumstances, they may choose to host it themselves. Opera Unite is our way of removing people’s reliance on the big datacenter solution, not because big servers are necessarily bad, but because they’re not enough.

Millions of people are comfortable with other people hosting their data, but there are also plenty of people who aren’t so comfortable, either because it’s a hassle, hard to use, or because of privacy concerns. I share photos online (Flickr, Facebook, and My Opera) but that doesn’t mean I want to share all of my “stupid digital photos” on the public web. Just today, I used Opera Unite to share some content with close friends that I wouldn’t necessarily want to put on Facebook, Flickr, etc.

When possible (depending on one’s router and the design of particular Unite services), Opera Unite supports UPnP (enabled by default) so that users can bypass Opera’s proxy service. Even when that proxy service is used, the data that passes through it is not stored by Opera.

At the end of the day, Opera Unite is still a work in progress, and we need informed, critical voices as well as enthusiastic ones to make it all work. Your feedback has been valuable, and I’m glad I had the opportunity to clarify some issues (even if some points of disagreement persist). People have always counted Opera out, but the company has been around for 15 years, and we’re going stronger than ever on multiple fronts (including the desktop). We did make ambitious statements about Opera Unite, and big claims paint a target on our back, but we think it’s better to aim high and not give up, even if we stumble a little out of the gate. Maybe I’m just an idealistic American, but I think the best is yet to come.

Did you have a look at Opera Unite yet?
