My Outlook started sending empty emails. The really annoying thing was that I could spend an hour composing the perfect email, hit Send, and it would strip the content before sending. The email in the Sent folder was devoid of content too. Gone!
I dunno if the following really fixed it, or if it simply went away on its own at the same time:
- File > Options > Mail > Compose messages in this format:
- Set it to Rich Text
- Send an email. It works!
- Set format back ot HTML. It still works!
