@jkrc717 I'm also getting the same error (85010017) on my 928. Have had trouble syncing when the problem was happening for most people and it's still not working (even tho Microsoft says the issue has been resolved).
I found this old article,
Support Code 85010017 - Microsoft Community, which basically suggested to sync less stuff and see if that works. I changed my sync settings to only do 3 days instead of 2 weeks on my phone, but that didn't help. Then I went into my email on my computer and deleted all messages with attachments (I get a lot of large .tif files) over the last three days since maybe that was too much to sync, but no dice. Haven't had trouble syncing those larger email attachments in the past, btw.
So I'm also at a loss and this is quickly escalating from irritating to crippling. I've already missed many impt msgs while on the go yesterday. Anyone have any ideas other than the nuclear option of reset?
