If you carefully watch the progress during the sync of a folder with greater than a couple thousand messages, you will see 'Updating local.' a lot before the newer mail starts arriving (newer than the initial 512 that come down). This is also further exacerbated by an Exchange issue where it gets unnecessary change events before the newer mail arrives. This is why it will look like you are not getting new mail when a folder is still going through initial sync.

Due to the design of Outlook's sync engine (and how exchange works), you will see the 512 newest messages in a folder at the initial start of sync then the rest of the folder's contents will be back filled before you see any mail that arrives after this point. Do NOT make subfolders under the Inbox.Īny folder with more than a few thousand messages is going to take some time to fully come down when you first sync your account. (this is the number one cause of problems with sync). The Inbox syncs more frequently than any other and should be kept as clean as possible.

Perhaps improving your Inbox will free up the sync to server so outgoing mail will send before timing out. We aren't seeing reports on this forum about outgoing messages saved to drafts so I have nothing specific to suggest other than to post the basics that help explain how Outlook syncs to the server.
