[TMB_XV6700]

This is really just an FYI.
Not sure if this registry entry was modified by Microsoft, Helmi, or the kitchen staff (or anybody), but I came across the consequences this week while standing at a rental car counter in a distant city. As a habit, when I travel I just paste relevant flight, hotel, and rental car information into the notes section of a calendar entry. This time, my information included some internet tags that made the size balloon up a little, and the note was truncated with a reminder that if I edited the appointment on the device all the associated notes on the server would be overwritten. Up to WM2003, there was no limit on the notes size, but WM5 supposedly introduced a 5kB default limit. Turns out my limit coming out of the kitchen was 1kB.

The associated key is
[HKEY_CURRENT_USER\Software\Microsoft\ActiveSync]
"BodyTruncation"=dword: Change from 1020 to 5120 (Decimal)

This change worked fine for me, as does bumping the dword value up to 20480 (Decimal),
supposedly the absolute upper limit in WM5.
