I use Outlook 2013 as my mail client, and I have an account configured with IMAP. However, syncing is either delayed or not performed.
There used to be emails in my inbox, but Outlook cannot archive due to sync issues and so yesterday morning I dragged all the emails from the Inbox (200 emails only) and my sent items into my archive. Therefore I have an empty inbox currently.
Since then, I have received many emails on my phone. However, Outlook still does not have it. I click on the Inbox and Outlook automatically starts to sync (as indicated in the 'status' bar at the bottom). However, the inbox folder remains empty. I click Send Receive, and it takes longer, but again, the folder remains empty.
So, to clarify, the inbox used to work (receive email), but no longer works at all, but regardless the syncing can be some what delayed. I could get an email on my phone, and not get the email in Outlook for many hours (despite manually syncing)
I used the same email account when I was on Outlook 2010 and never had this issue. My mobile phone, which also syncs via IMAP, does not have this issue. Therefore, I'm hoping it's an Outlook 2013 bug or (more likely) my poor configuration. The issue I have is I don't know what I need to look for to fix it, and my searches only suggested I make sure I'm subscribed to the correct folder(s) which I am.
Within my settings I also just changed it to keep only 3 months off line.
