Thanks HeliosBean
The multiple accounts issue was my issue exactly. I am using Outlook 2003, IOS4.0.1, and Itunes 9.2.1.5.
On upgrade to ios 4.0, notes stopped syncing.
From what I can tell, once the os was upgraded, a "notes" section was added on my active accounts including my gmail account. In the notes application, the default view was "All accounts". However, creating a note defaulted to being created in the gmail account versus the outlook account.
Symptoms:
All outlook originated notes synced/updated fine.
All iphone created notes never showed up in outlook
I followed the steps from HeliosBean to find the multiple accounts. I then manually cut and pasted the notes from the "gmail" account to the "outlook" account.
Finally, I went into the mail settings and turned off notes for the gmail account.
Removing the notes from the "gmail" account reverted the notes application to just one account and removed the accounts page altogether in that app.
After this, I haven't had any problems, but I am only 2 syncs in.
