ActiveSync Won't Sync Online but will Offline

[robshobs]

ActiveSync has suddenly started acting strange (like that's a surprise to anyone). Everything was syncing just fine. I normally connect Outlook directly to the server when I start it. On Friday, all of my messages were available on my PPC.

On Saturday, the Exchange server was down, so I worked offline. Everything sync'd OK. Throughout all of these problems, my PC syncs every hour with the server.

Today, I connect to the server and sync. Now only one third of my messages are showing up in my PPC Inbox. I have not changes the setting of ActiveSync. The messages showing up are a random sample. For instance, my PC Inbox had 77 messages that date over the past 12 months. I have messages 12 months old and some one day old. About 10% of Friday's 35 messages are showing up in the PPC Inbox.

So I take Outlook offline and re-sync. Well what do you know, the PPC Inbox populates with all of the PC messages. GREAT. It works.

Nope. Go online and sync again and I'm back down the the same 25 messages.

Any ideas? How can I get ActiveSync to behave correctly both online and offline?

I have a HP IPAQ 5555.

Try uninstalling and reinstalling ActiveSync. Usually helps with the weird problems. You might want to download the latest ActiveSync while you're at it (if you haven't already).
