Windows 7: Windows Live Mail Server Error

Windows Live Mail Server Error

Beginning yesterday, I can no longer connect to my msn account via WLM. If I go directly through hotmail, I can sign in and all is well. I tried reconfiguring my WLM for the msn account, but that didn't work.

Here's the error message I get:

Unable to send or receive messages for the Msn (xxxxxxxx) account. Sorry, we were unable to sign you in to Windows Live ID at this time. Please try again later.

Server Error: 0x80048820
Server: 'http://mail.services.live.com/DeltaSync_v2.0.0/Sync.aspx'
Windows Live Mail Error ID: 0x80048820

As far as I know, nothing was updated yesterday, so I'm not sure why the sudden problem...

While I do use WLM, I use it to access POP3 and IMAP accounts as we did with Windows Mail in Vista and Outlook Express in XP/Win98. In WLM Microsoft has added Hotmail access via the HTTP protocol accounts and delta sync. Upon Googling the specific error number in your post, I found a discussion of your particular server error and a (complicated) way to tackle it using a command prompt (>): Windows Live Mail Server Error: 0x80048849 and/or 0x80048820

What it basically says to do is check the MTU of your network connection to the mail server by pinging it with different sizes of the MTU until you find the one with no packet loss, starting with 1500:
>ping 65.55.33.106 -f -l 1500

if 1500 fails, but 1472 works then reset it to 1472:
>netsh interface ipv4 set subinterface "NIC name" mtu=1472 store=persistent

To find the NIC name or verify the change, use this:
>netsh int ip show int

I've substituted the command to change the MTU to one used in this post because it worked based on the above verification command to "show" the interface: Tinypic will not load on one computer whereas the one shown in the Microsoft post did not pass the above verification test on my Windows 7 system.

Here is a link I found to an automated MTU test: http://qsextreme.com/mtutest/. That discussion says that you can add 28 bytes to the maximum size obtained from the ping test, so if the sucessful ping test occurrs with a maximum packet size of 1472, the MTU can be set to 1472+28=1500. (FWIW, 1472 was the recommended value I received from the automated test based on a discovered maximum ping value of 1444. 1472=1444+28)
