Outlook – Getting IMAP push notifcations to work in Outlook 2013

The issue is that Outlook need someplace to store the local items, such as your Tasks, your Calendars, Notes, etc. With IMAP mail servers, your mail lives on the IMAP server, and it can have it's own folder structure aside from the local folder structure. This is why you see both 'trees'. When you use Outlook with POP3 mail servers, POP3 functions differently; the mail is downloaded from the POP3 server and then stored in your local mail folders (and then usually deleted from the POP3 server). So you only ever see one 'tree'.

You mention that with Exchange you don't see the 'Outlook Data File', that's because Outlook works with the exchange server directly, and the Exchange server is your 'Outlook Data File'. That is, the Exchange server is the storage location for all our email, tasks, notes, calendar, etc. If you then add an IMAP account, you should see both the Exchange Mailbox and the IMAP folder structure similarly.

To answer your questions directly: I'm not sure if you can set whether various panes are hidden or shown by default; you might be able to accomplish this via Group Policies but I'm not sure. I suspect you would need to go to the individual machines and just do these things and then it will remember how you have things arranged. You can however remove the Data File version of 'Inbox' and other folders from the favorites and instead add the IMAP versions (they will look different though).

Regarding the Junk-Mail settings, there's a difference when you're using Exchange server. Exchange server itself is [generally] capable of handling junk mail, and it can scan and move mail into the junk mail folder without the intervention of Outlook. This is different than an IMAP server, again keeping in mind that your mail lives on the IMAP server, Outlook is not actively monitoring incoming mail for you. Instead, when you connect to the IMAP server, the IMAP server tells Outlook what mail is there waiting to be read. For the most part you would need to have some server side junk mail filtering going on to effectively deal with the junk.

I hope that helps, even though its probably not the answers you wanted.

In the end I solved the problem by unsubscribing from IMAP folders I didn't want to use. In my case it was: - Gmail/All_messages - Gmail (Gmail - Inbox)

To do it, you just go to Folder => IMAP Folders => and deselect those you don't want to download to Outlook.

Another option is to go to Gmail web mail (gmail.com) => Settings => Labels => And set labels you don't want to synchronize with Outlook to not show in IMAP access
