Things that have changed
Outlook 2007 | Is this
an issue? | Impact |
No support for
animated gifs
|  | The image will be rendered as static, only the first frame will display.
Ensure your animated gifs have a link in the first frame. |
No support for Flash
or other plug-ins
|  | Email was not designed for Flash, this is not a new issue as it
has always been a problem. |
No support for CSS
floats/positioning
| | Not best practice - This has been an issue with a number of the webmail
clients such as Hotmail, Gmail and Yahoo. |
No support for using images
as bullet in unordered lists
| | Easy work around using a table instead of an unordered list. This may
be slightly more difficult for non technical users. |
Background images will not
render
| | Not best practice - Due to issues with other webmail clients such as
Hotmail, Gmail, and Yahoo. |
Forms will not display
properly
| | Not best practice - Forms have been a problem with previous versions
of Outlook and other webmail clients such as Hotmail, Gmail, and Yahoo. |
Poor background colour
support
| | Only an issue if using background colour in nested tables. |
| Alt tags will be modified | | Keep Alt tags concise and to the point. Start them with descriptive copy so if they
get cut off... |
