I have 3 IMAP accounts seed up on my outlook and normally its shoved all account inboxes (sent mails and deleted mails as well) under INBOX:

But couple days ago its stopped to show them after i am pressing send/Receive button.

Its shoving only one account ( and it is not primary account).

If i quit outlook and start it again its again shows all accounts, but as soon i press send/Receive it don't again.

How to fix it?
