Having a strange issue and I think my WP7 Focus is the culprit. For the last few weeks, I'd been noticing that there were emails marked as read in my personal Gmail inbox, but I hadn't read them--I actually missed a few emails because of this. I thought it was related to my Google Chrome mail-checker extensions, as I also have a Google Apps work email on my phone and that account is fine.
However, after paying more attention, it seems to be WP7 related. I no longer use any mail checking extension in Chrome, but all of my email that I receive overnight is marked as read. I have to go in and check my mail, finding that anything sent after 10 (I work early, usually passed out by 10) at night is marked as read by morning.
I'm going to delete/re-add the account, but has anyone had this before??
