Microsoft Outlook.com app notification Some information:


I have 1 gmail account for my business/work related emails only I
have an outlook.com account for my personal emails 
I have another gmail account for non-important things i.e. newsletters and freebie
sites and other 'spam' type mail.


I would like to use the gmail app on my phone for the business emails only and 
I want to use the outlook.com app to take care of both personal and non-important emails.

Steps taken so far:

I have installed the outlook.com app on my nexus 5, running the latest android. 

I have then added a secondary account to it, via the web interface on my computer. This is my second gmail account that is used for non-important things and is linked via the POP3 settings, and shows up as a separate folder next to the inbox/outbox in the outlook app.

The app is configured to notify me by both sound and vibrations (both options checked in the settings) - and it is configured to receive push notifications.

However, the app behaves quite strangely. For the main account (my @outlook.com address) the push notifications are pretty instant and the phone vibrates/makes a noise. For my secondary account (gmail linked via POP3) there is no notification, I see these updates when I open the app (it shows unread count). How can I make the phone notify me of ALL messages that appear in the outlook.com app.
You can't have email push notifications over POP3. It's an old protocol and simply doesn't support push. It doesn't matter what client you use or what kind of mail server.

If you can set up Outlook to access Gmail through IMAP instead of POP3, and if Outlook supports IMAP IDLE for push notifications, then you'll get push notifications. Otherwise, you might have to use a mail client that does support IMAP IDLE, such as K-9 Mail.
