How do I back up Outlook data to move it to another account?

  In Outlook, click File > Import andExport.

  In the Import and Export Wizard dialog box, do the following:

1. Under Choose an action to perform, select Export to a file, and then click Next.
2. On the Export to a File page, select Personal Folder File (.pst), and then click Next.
3. On the Export Personal Folders page, under Select the folder to export from, select Mailbox -<user name>. Select the Include subfolders check box, and then click Next.
4. On the Export Personal Folders page, in the Save exported file as box, note the location where the backup.pst file will be created. By default, it's C:\Users\<user name>\AppData\Local\Microsoft\Outlook\backup.pst. Under Options, select Replace duplicates with items exported, and then click Finish.
5. On the Create Microsoft Personal Folders page, click OK to create a .pst file. If you want, set a password to protect the .pst file, which will be named backup.pst. A password isn't required.

The Differences Between WEP and WPA

When using a wireless access point or router it is important to
remember that if you can send information from one device and receive
it at another, anyone else within range might also be able to receive
it. When protecting data send via wireless, security and protection is
offered through  encryption schemes that come with your wireless
hardware you can enable.

Short for Wired Equivalent Privacy (or Wireless Encryption Protocol),
WEP is part of the IEEE 802.11 wireless networking standard and was
designed to provide the same level of security as that of a wired LAN.
Because wireless networks broadcast messages using radio, they are
susceptible to eavesdropping. WEP provides security by encrypting data
over radio waves so that it is protected as it is transmitted from one
end point to another.

WEP was the encryption scheme considered to be the initial standard
for first generation wireless networking devices. However, it has been
found that WEP is not as secure as once believed. WEP is used at the
two lowest layers of the OSI model - the data link and physical
layers; it therefore does not offer end-to-end security.

WEP's major weakness is its use of static encryption keys. When you
set up a router with a WEP encryption key, that one key is used by
every device on your network to encrypt every packet that's
transmitted. But the fact that packets are encrypted doesn't prevent
them from being intercepted, and due to some esoteric technical flaws
it's entirely possible for an eavesdropper to intercept enough WEP-
encrypted packets to eventually deduce what the key is.

This problem used to be something you could mitigate by periodically
changing the WEP key (which is why routers generally allow you to
store up to four keys). But few bother to do this because changing WEP
keys is inconvenient and time-consuming because it has to be done not
just on the router, but on every device that connects to it. As a
result, most people just set up a single key and then continue using
it ad infinitum.

Even worse, for those that do change the WEP key, new research and
developments reinforce how even changing WEP keys frequently is no
longer sufficient to protect a WLAN. The process of 'cracking' a WEP
key used to require that a malicious hacker intercept millions of
packets plus spend a fair amount of time and computing power.
Researchers in the computer science department of a German university
recently demonstrated the capability to compromise a WEP-protected
network very quickly. After spending less than a minute intercepting
data (fewer than 100,000 packets in all) they were able to compromise
a WEP key in just three seconds.

It wasn't long before a new technology called WPA, or  Wi-Fi Protected
Access debuted to address many of WEP's shortcomings.

WPA aims to provide stronger wireless data encryption than WEP, but
not everyone has or was able to jump onboard with the new wireless
encryption technology. In order to use WPA all devices on the network
must be configured for WPA. If a device is not configured for WPA, it
will usually fall back to the lesser WEP encryption scheme, enabling
the wireless devices to communicate on the network. The technology was
designed to work with existing Wi-Fi products that have been enabled
with WEP (i.e., as a software upgrade to existing hardware), but the
technology includes two improvements over WEP:

       *  Improved data encryption through the temporal key integrity
protocol (TKIP). TKIP scrambles the keys using a hashing algorithm
and, by adding an integrity-checking feature, ensures that the keys
haven't been tampered with.
       * User authentication, which is generally missing in WEP,
through the extensible authentication protocol (EAP). WEP regulates
access to a wireless network based on a computer's hardware-specific
MAC address, which is relatively simple to be sniffed out and stolen.
EAP is built on a more secure public-key encryption system to ensure
that only authorized network users can access the network.

WPA has been a mainstream technology for years now, but WEP remains a
standard feature on virtually every wireless router on store shelves
today. Although it's mainly there for backward compatibility with the
oldest hardware, if reports and studies are accurate, a significant
percentage of WLANs operating today (especially those used in homes)
are still using outdated and insecure WEP for their encryption.

Widespread use of WEP is almost understandable given that to the
layperson, the similar abbreviations WEP and WPA don't convey any
meaningful difference between the two security methods (and they may
even imply equivalence) Plus, WEP is almost always presented first by
the security interface of most broadband routers since WEP comes
before WPA both historically and alphabetically).
