Long Links Break Apart in Emails

Outlook 2011 connecting to Exchange 2010. Full patched Outlook and Exchange server.

Plain Text email format.

I want to send someone a link, such as:

http://www.neweggbusiness.com/Product/Product.aspx?Item=N82E16828118627&nm_mc=KNC-GoogleBiz&cm_mmc=KNC-GoogleBiz-_-pla-_-Printer+-+Laser+Printers-_-N82E16828118627&gclid=CPf4oZWPgrUCFUjZQgodV0sALQ

The resulting link breaks up after 80 odd characters, in the case above, after the "&nm" part. So my link ends up looking like:

http://www.neweggbusiness.com/Product/Product.aspx?Item=N82E16828118627&nm
_mc=KNC-GoogleBiz&cm_mmc=KNC-GoogleBiz-_-pla-_-Printer+-+Laser+Printers-_-
N82E16828118627&gclid=CPf4oZWPgrUCFUjZQgodV0sALQ

Because of the broken up link, only the first line is clickable. So my recipients get "link not found" errors because they are only able to click on a portion of the link.

(Note that the above link to the newegg business site is actually smart enough to know what I want to see without needing the remaining characters of the link, but that's because of the newegg's webserver acting intelligently - outlook 2011 is still breaking up the link)

If I send this link to a gmail user, the link is fine. If I send it to another Outlook 2011 user, or if I look in my Sent items, the link is broken.

How do I fix this?
