I am running Outlook for Mac 2011 version 14.0. This is at work so its on a server. In the lower right corner of the Outlook page, it is constantly uploading 4 messages. Once it finished, no emails appear in the inbox and the upload just starts again after a couple minutes. Each time it uploads, it takes about 10-15 minutes. I am able to send and receive all other email, but receiving is VERY delayed. I know this because we have web-based email also that I can check.
