- Outlook version
- Email Account
I have several Windows devices running either Outlook 2010 or 2013. I also have 2 Windows Phone with Outlook. I use one Microsoft account and sync all of these with the Outlook connector for the 2010 version or EAS sync for 2013. Mail comes in fine on all devices. However, many times when I delete a message on one machine it does not delete on the others. It seems random, sometimes they delete and sometimes they don’t. I check Outlook.com and it always deletes there, but it seems the devices are unable to sync correctly with Outlook.com. So all my various devices now have emails that have been deleted on other devices. None of them have the same emails. Why does this happen? Is it a bug Microsoft has not fixed? Is there a way to fix it? Can I delete the .ost files and let it resync?
