Recently our company deployed iPhone 8plus with company email. Basically, functions of sending and receiving email is working fine. then I found the Draft folder was not sync'd.
So I went into Settings -> Accounts & Passwords -> Fetch New Data. It's confirmed the corporate email was set to "Push" automatically. Then I taped into corp email and did not found Draft folder under "PUSHED MAILBOXES". There are only Inbox, Sent, Trash, Junk...etc.
Below is the version of iOS and activesync:
Device OS: iOS 11.3.1 15E302
ActiveSync version: 14.1
Appreciated if someone could help to advise what I miss or it's by design that Draft is no longer sync'd
Thanks!
