First off, loading messages can often take an unreasonably long time. For example, I click to expand a two paragraph text-only message, and it takes ~5 seconds to load.
And then 4/5 times I try to send a message, it just hangs with the sending animation looping. Eventually I refresh or it times out and I see double drafts in the draft folder, and nothing in the sent folder. Sometimes I refresh and it appears that the message has been sent, but I'm never sure.
Also, on a side note: I had a look in an old Hotmail account of mine, and it's completely empty. Luckily this was not an important account of mine (I primarily use gmail), but it sure looks like Microsoft did a stellar of the switch over.
I think the outlook.com interface is excellent, and I'd like to sort out the issues mentioned above. Has anyone experienced any of this weirdness?
