Tip & How-To about Computers & Internet

Outlook Security Update stops you open "unsafe" file types, plus you get a warning if a script tries to read your addressdata or send emails without permission. Specify the types of files can be opened with mounting options (www.slovaktech.com / attachmentoptions.htm).

why can't i read my message and my friend's message while chatting?

One of you has a scripting problem.
When you type a message and 'send' it, you should be able to read it in the upper conversation window. When you receive a message, it should be visible in the Conversation window.
If this is the case the fault lies with your contact's computer.

Email this to them:
You may have scripting disabled in your Internet Explorer.
To enable scripting:

Click "Tools"
Click "Internet Options."
Click "Security" tab.
Click "Custom Level" button.
Scroll down to "Script ActiveX controls marked safe for scripting"- enable
Scroll down to "Scripting - Active scripting" - enable
Scroll down to "Scripting of Java applets" - enable
Click OK
Click OK
Restart Internet Explorer
Still not working ? Update software

Below is a link to help update software.


After updating, check if you do not have Old Versions of Flash player, Shock wave player and Java running alongside the latest/newest - these can cause conflicts
Start / control panel / programs/
now delete any old versions.

Best of luck to You. Hope this helps.

Server Error 553, ErrorNumber 0x800CCC78

(Outlook Express) Email is not configured to relay mail to address
Try this settings:

Outlook Express
  1. Click Tools then Accounts
  2. Click Mail
  3. Click Properties
  4. Click Servers
  5. In the Account Name field, it should be the first part of your email address (probably it's like this already).
  6. Put a checkmark by My Server Requires Authentication at the bottom of the page.
  7. Click Settings
  8. Select Log on Using
    • Type Account Name (which will be your full email address)
    • Type Password (which will be your email address password)
  9. Click Apply
  10. Click OK
  11. Click Close
This should fix the Outlook Express to send email, close Outlook Express and re-open it to start sending mail.

Microsoft Outlook
  1. Click Tools then Email Accounts (Accounts and Services on older versions of Outlook)
  2. Click View and Change and Click Next (skip if it opens up to the account screen)
  3. Click Change or Properties of your Email Account
  4. Click More Settings
  5. Click Outgoing Server
  6. Check My Server Uses Authentication
  7. Select Log on Using
    • Type Account Name (which will be your full email address)
    • Type Password (which will be your email address password)
  8. Click OK
  9. Click Next
  10. Click Finish

This should fix the Outlook to send email. Close Outlook and re-open it to start sending mail.

it depends on the type of file. many types of files can be used to harm other people's computers. this is why viruses spread.

Receive Security Warning

So this is in your internet window? Pretty much all internet windows are unencrypted and unsafe. Use Outlook for encryption. It is more than likely is a generic XP warning window. Click on it and should just redirect you Yahoo. Yahoo mail, hotmail, gmail, they are all encrypted to a certain degree. Don't send passwords, bank account info, etc. through email though. Hope that helped.
