To connect to LetNet wireless your computer must have a wireless adapter that supports connections via Protected EAP (PEAP) security.

Some computers may have a built-in third-party wireless utility that controls your computer's wireless connections. We do not support how to connect through this software. Please disable any third-party wireless management utilities and follow these instructions to use Windows 8.

General Security Settings:

SSID: letnet (must be all lowercase)
Network Authentication: WPA2 (Enterprise)**See Special Note**
Data Encryption: AES
Authentication Type: PEAP
802.1X: Enabled

OLDER LAPTOPS AND DEVICES (if your device does not support WPA2/AES):

SSID: letnet-legacy (must be all lowercase)
Network Authentication: WPA (Enterprise)
Data Encryption: TKIP
Authentication Type: PEAP
802.1X: Enabled

**Special Note**
Some Windows 8 clients may not be able to connect to the letnet wireless SSID

Workaround

1. Connecting to letnet-legacy should work, provided you are using WPA/TKIP.

2. Use a Windows 7 wireless driver instead.

Please call the IT Helpdesk at (903) 233-3500 for additional assistance.

The two things to remember when making calls on-campus are:

1. On-campus numbers are dialed with only 4-digits.
2. You have to dial 8 to call an off-campus number.

Destination	How to Dial
On-campus	4-digit extension
Off-campus (local)	8 + 10-digit phone number
Long distance	Students: 8 + calling card phone number  Faculty/Staff: 8 + 1 + 10-digit phone number + long distance code
International	Students: 8 + calling card phone number  Faculty/Staff: 8 + 011 + International code + phone number + long distance code

LetNet Webmail

LetNet Webmail is probably the easiest and most convenient way for many people to use LETU email. To use LetNet Webmail, in your web browser, go to https://mail.letu.edu/, and log in using your LetNet account.  You'll then be presented with the LetNet Webmail interface, pictured below.

Outlook Anywhere

If you own Microsoft Outlook you may set it up to access email directly using Outlook Anywhere. Click here to view the Outlook Anywhere instructions.

Other email clients

Instructions for setting up Exchange mode on other email clients are available here.

Instructions for other methods (POP3/IMAP) are available on the LETU E-mail website.

Outlook provides a function called Favorite Folders which allows you to view the contents of frequently-viewed public folders easily from your main Outlook view without having to visit the All Folders tree-view of the public folder structure.

• You should have a button on the bottom-left menu of your Outlook called Folder List (see example screenshot below):
  
• Once you click on Folder List you should see a different view of folders - the top part of which is your normal email box folders and which at the bottom has an entry Public Folders
• You can access the delivered email for any particular public folder by browsing to your folder as in the example below:
  All Public Folders
    Faculty Staff
      Department
        FolderName
• If you'd like to be able to see the status of new items in that folder easily from the main page you see with your Outlook Inbox:
• Right-click on the FolderName folder and choose Add to Favorites
• Select OK for any prompts following.
• Then go up above in the Favorites section of the folder tree and right-click the copy of FolderName there and choose Add to Favorite Folders.
• This folder should now show up on the top-left corner of your outlook when you return to your normal view by clicking on the "Mail" view button on the bottom-left of Outlook. See below for an example of the final result - these folders will show unread message counts and bold on unread email just like normal Outlook folders.
  
  
  

• If you already have Outlook up and running with another account, close Outlook.
• Go into Control Panel and find "Mail".
• The Mail Setup - Outlook should appear, click on Show Profiles

• Find the profile you are using, it will say always use this profile and list it at the top, in this example, this computer is using the profile "Outlook". If there isn't a profile, click on Add, give it a name and click OK.

• Once the profile is ready, click on Properties.

• Click on E-mail Accounts.

• Once in Account Settings, click on New...

• Leave everything as default on this screen, click on Next.

• Type in your First and Last name for "Your Name", your LETU e-mail address and your LetNet password and click on Next.

• You may be prompted for a password, if you are, be sure and put letnet\yourletnetname in the user name where yourletnetname is your LetNet user name.

For outlook 2007: On the Tools menu, click Account Settings, select the Exchange account, and then click Change.

For outlook 2010: Select the File tab on the ribbon at the top. Then Select Account Settings.

For both Outlook 2007/2010:

• Ensure the box labeled Use Cached Exchange mode is checked. Outlook Anywhere will work very poorly without this critical step.
• Click More Settings, and then click the Connection tab.
• Under Outlook Anywhere, select the Connect to Microsoft Exchange using HTTP check box.

 Note   If the Outlook Anywhere section is not available, your computer is probably not running Windows XP Service Pack 2 or a later service pack. You need Windows XP SP2 or later in order to use this feature.

• To specify a proxy server, click Exchange Proxy Settings.

 Type in mail.letu.edu for the URL to connect to my proxy server.

 Select the Connect using SSL only check box.

 Select the Only connect to proxy servers that have this principal name in their certificate check box, and then type msstd:mail.letu.edu.

• Under Proxy authentication settings, click NTLM Authentication.

You now should be able to sync your Outlook client using Outlook Anywhere!
