I recently signed up for outlook.com email. I've had problems sending mail (account is temporarily blocked) and attempts to verify the account fail. I'm blocked from forwarding an email because the account isn't "verified" but attempts to verify fail. Now I find that emails with attachments are not reliably getting through to me. Two emails that displayed on my iPhone that had attachments were never visible in either the web client or Apple Mail or the Outlook desktop client. Then they mysteriously disappeared from my iPhone, Outlook and the web client. On the web client, they're not in junk, deleted items or anywhere else. Later they mysteriously again re-appeared in the trash. I moved them back to my inbox and a few minutes later... Back in the trash. Either way, when I click on the message, the attachment doesn't show anywhere where I can download them. Both are extremely important, both are purchase orders from my customers. When I moved them back to the inbox and they showed up momentarily on my iPhone and Outlook, the attachments have a file size of 0 KB! I know Microsoft is trying to protect me from spam, but this is just amazingly absurd.
