I’ve just been fighting with this today. Let’s call the behavior of removing the extra line breaks “continuation.” A little experimenting finds the following behavior:
- Every message starts with continuation off.
- Lines less than 40 characters long do not trigger continuation, but if continuation is on, they will have their line breaks removed.
- Lines 40 characters or longer turn continuation on. It remains on until an event occurs to turn it off.
- Lines that end with a period, question mark, exclamation point or colon turn continuation off. (Outlook assumes it’s the end of a sentence?)
- Lines that turn continuation off will start with a line break, but will turn continuation back on if they are longer than 40 characters.
- Lines that start or end with a tab turn continuation off.
- Lines that start with 2 or more spaces turn continuation off.
- Lines that end with 3 or more spaces turn continuation off.
Please note that I tried all of this with Outlook 2007. YMMV.
So if possible, end all bullet items with a sentence-terminating punctuation mark, a tab, or even three spaces.
