Configure HTML Security in Microsoft Office Outlook

Microsoft Office Outlook may block or warn before sending MLS reports that use HTML code (HTML link or Embedded HTML). (To fix a CDO Error, see CDO Error at the bottom of this screen or the Fix CDO Error related article.) Blocking HTML code is intended to prevent junk email senders from identifying your address as active. However, it may also block legitimate HTML email code (such as used by MLS reports). The warning is to help prevent some virus from automatically sending itself out through your Outlook email address book without your knowledge.

To set Outlook 2003 (or later) to not block sending HTML code, you can either (1) turn off its "Don’t download pictures or other content automatically in HTML e-mail" security option; or (2) add www.ctimls.com to your Internet Explorer’s Trusted Zone and set Outlook to permit downloads from web sites in your Trusted Zone.

I. To turn off the "Don’t download pictures or other content automatically in HTML e-mail" option in Office Outlook 2003 (or later):

1. Start Outlook. 
2. On the Tools menu, click Options. 
3. Click the Security tab, and then click Change Automatic Download Settings.
4. In the Automatic Picture Download Settings dialog box, un-check Don’t download pictures or other content automatically in HTML e-mail check box.
5. To stop the Outlook warning when sending messages with HTML code, un-check "Warn me before downloading content when editing, forwarding, or replying to e-mail"
6. Click OK twice.

For further details about Outlook 2003’s security options, see "Safe Senders Option in Outlook 2003" in related articles below. For security information about earlier versions of Outlook, see Microsoft Help for Office Outlook in related articles below.

3. Click on Trusted Sites > then Sites button
4. Un-check “Require server verification (https:) for all sites in this zone"

(www.ctimls.com should be in your Trusted Zone as described above.)
6. Click OK twice to close the Tools screens.
