Hello-
We are running a single Exchange 2013 SP1 server and clients are running Outlook 2013 SP1. What we are finding is that since we enabled MAPI over HTTP random messages are not appearing in some user mailboxes, but they are showing on their ActiveSync devices. Closing and opening Outlook does not trigger the messages to appear in Outlook, but clicking the Update Folder button on the Send/Receive tab does. Clicking the Update Folder button seems to be the only way for these messages to appear as clicking Send/Receive All does nothing either.
This problem was introduced immediately after updating Exchange to SP1. Are there any known issues that would cause this type of behavior where messages are missing in Outlook until the Update Folder button is clicked? Outlook shows as connected the entire time and other messages will come in and be sent just fine.
Thanks.
