Software :: Won't Sync Mail Accounts With MobileMe

I have an Apple laptop and an Apple desktop. Both are running 10.5.4 and have the MobileMe 1.1 s/w update.

On the laptop, I've set up my Mail accounts, contacts, keychains, bookmarks, etc. as I want them.

I access MobileMe in System Preferences and indicate I want all data on MobileMe replaced by the data on my laptop.

As soon as the sync has completed, I access MobileMe in System Preferences on my Desktop and indicate I want all data on my desktop replaced by the data on MobileMe. Unless I'm missing something, the laptop, MobileMe, and the desktop should all by in sync at this point.

Without touching either computer or accessing MobileMe, I'll get a message on my laptop and/or desktop within an hour telling me that more than 5% of my Mail accounts have changed and asking me what I want to do. If I look at the details of the change, the before and after views of the account are absolutely identical. I've tried resetting the sync history via iSync but that doesn't help. I really don't want to alter the changed percentage that triggers the message because it could be useful for Contacts, etc.
