html - Anchor links pointing to external site issue in Outlook -

my issue straightforward: generating newsletter webpage design in html. create anchor links connect summary section different parts of newsletter.

i have tried following

<a href='#part1'>click here part 1</a> [etc...] <a name='part1'>part 1</a> 

the problem when html page generated replaces #part1 www.mypagename/test.html#part1, providing reference external page. links anchor outlook email , not external page (just #part1!!).

how can achieve this? thank time.
