I am supporting a longtime hotmail user who is having trouble with his hotmail account.

He reports problems both in sending and receiving mail.

He often uses browser to view email via outlook.com on a browser, but he also uses ipad and iphone as well as both Mac and Windows computers.

Issues seems to exist on all platforms.

I have been testing using Chrome 30 on a Windows 7 computer.

His account shows only one received  email since Nov 2.  I have sent messages that are not showing in his inbox or junkmail.  My server reports successful delivery to his email server.

I have used webmail interface to send outbound mail.  When I click send I get a message at the top saying "Sorry, Outlook wasn't able to complete this request."  When I click on inbox or other folder to change view I get a warning notice saying I am leaving the page without my message being sent.

The sent messages are actually received at the other end, however they are not showing in the sent folder.

For trouble shooting I have tried:

clearing browser cache 

moving 228 of 9975 messages in the sent folder to another folder

Testing after each of these has resulted in the same behavior.
