Evo Shift, set to 3G only. using Exchange Activesync
I have an ongoing issue with emails that go missing from my phone after a few days. I am able to sync without any issues. But every day or two several emails go missing from my phone that were previously shown. They are still on the exchange server. If I remove and re-sync the account, all the emails show up. But after a few days, some go missing again. I use categories with my emails and thought this may be the issue.
Sprint is no help.
Have several android phones on the same exchange server, even one HTC Inspire and no one else has this issue.
I have tried several different setting with always the same result. Have 14 days shown, conflicts to leave on phone, sync every 15 minutes weekdays, every hour weekends. Using exchange 2007.
