If you receive Server Error: 0x80048849 and/ or 0x80048820 in Windows Live Mail at home or while you're in your regular network, it may be due to the setting of the MTU (Maximum Transmission Unit) on the mail client.
If you get this synchronization error at a coffee shop, airport or a place from where you don't usually connect to the internet, we suggest synchronizing mail on your regular internet connection.
When the MTU setting on the mail client is larger than the MTU settings configured on network devices between your mail client and the mail client servers, some data packets may be lost, causing mail synchronization to fail.
Follow the steps given below to fix synchronization errors due to mismatched MTU settings:
Determine the MTU setting on your network device
Apply the MTU setting to your mail client
Determine the MTU setting on your network device
This is a trial and error process, and will be different for each user. You may have to repeat the procedure below a few times, before you can find out the MTU setting of your network device. Follow the steps below:
Open command prompt
Click Start ? Run ? Type cmd
In the Command Prompt Window, type in the following:
Ping <Mail server address> -f -l 1500
Notes:
The <Mail server address> is the IP address of the mail server that you are unable to synchronize with.
For Hotmail, 65.55.33.106 is the IP address for DeltaSync (mail.services.live.com).In this document we will be using this IP address as an example.
In the -l 1500, 1500 is the max MTU for Ethernet connections.
You may get an error like this (100% packet loss):
C:\Users\username>ping 65.55.33.106 -f -l 1500
Pinging 65.55.33.106 with 1500 bytes of data:
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Packet needs to be fragmented but DF set.
Ping statistics for 65.55.33.106:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss)
If you received the error above, subtract 28 from the 1500 bytes of data. In the Command Prompt Window, type in the following:
Ping <Mail server address> -f -l 1472
If you get a 0% Packet Loss with 1472, it means the MTU setting of your configured network is 1472
Note: If you continue to receive the error described in (b) above, repeat the above steps by subtracting 28 from 1472 bytes of data. Repeat these steps until you get a message for 0% packet loss. If you were able to communicate with the mail server at an MTU size of 1424, you will receive the following:
C:\Users\username>ping 65.55.33.106 -f -l 1424
Pinging 65.55.33.106 with 1424 bytes of data:

Ping statistics for 65.55.33.106:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss)
Approximate round trip times in milli-seconds:
Minimum = 162ms, Maximum = 230ms, Average = 187ms
Apply the MTU setting to your mail client
Follow the steps below:
Open command prompt as administrator (you must be an admin on the computer)
Click Start ? Run ? Type cmd
In the Command Prompt Window, type in the following:
netsh int ip show int
You will receive a message similar to the following. Find the connection name that you use to connect to the internet and note the Idx value
C:\Users\Username>netsh int ip show int
Idx Met MTU State Name
--- ---------- ---------- ------------ ---------------------------
1 50 1472 connected Loopback Pseudo-Interface 1
11 20 1472 connected Local Area Connection
To apply the correct MTU setting on your mail client, type the following in command prompt:
netsh int ip set interface <Idx value> mtu= <MTU setting of your router> store=persistent
Press Enter
For example, if the correct MTU setting was 1424 and Idx value of your connection was 11, you will type:
netsh int ip set interface 11 mtu=1424 store=persistent
If (c ) was successful, you will receive the confirmation message "Ok"
Exit command prompt
Restart your computer
Open WL Mail and see if the issue persists.

The issue here would appear to be with the communications between the laptop and the server or wireless access point. Can you get other laptops to access the internet using your server?
Unfortunately, many people seem to fixate on the error number at the end - 0x800ccc0d. While that can be useful, and it's easy to search on, they're missing all the additional information that Outlook is providing in the error. Specifically, this:
"If the Incoming Mail (POP3): setting is wrong, then error 0x800ccc0d can result."
If you have more than one account, you may see multiple items in the list. Click on the one with which you are having trouble and click on Properties. In the resulting dialog box, click on the Servers tab and you should see something like this:
Note the arrows pointing at the two instances of the mail servers you would be using: one for POP3 (incoming email) and one for SMTP (outgoing email).124 views
