I am having a major problem with the Windows 10 mail app.
I have a single Gmail account that I'm trying to use with it, and basically nothing syncs. Occassionally the Inbox will sync, but it's sporadic, so I'll have messages from a week ago and the app will try to tell me that it's "up to date." Folders simply do not sync at all, giving a variety of messages ranging from "Still working on it" to "Not synced yet" to "nothing to sync." This includes All Mail, Sent Mail, and more.
Basically this renders the app useless. Because of the sync issues, I can't count on notifications or the live tile to be correct. Any sort of Cortana integration is a bust too. One of the core components of this new operating system is completely non-functional. The Windows 8 Mail app wasn't anything to get excited about, but it worked pretty flawlessly as basic as it was. I had no problems with it, and honestly wish I could have it back. The Windows 10 app looks nice, but it just plain doesn't work.
Can anybody help me fix this?
For the record, I've tried removing and re-adding the email account, as well as toggling the privacy settings under Contacts and Calendar. Any advice would be much appreciated.
