Using Office 365 E3 plan
Service upgraded 3 days ago.
Since then i'm receiving new emails as draft.
On web apps outlook, in the inbox, on most of the mails received, it is written draft- massage not send and my mail address shown instead of the sender address.
On the local computers, using Outlook 2010 pro, sender is correct but the icon of most mails is draft icon. Only if we reply to the mail, icon change to email icon (the envelope)
