Exchange Mailbox/Mail-enabled Folder permissions required for push notification subscription
===

I need to subscribe for [push notification][1] on several Exchange mailboxes and mail-enabled folders using single Exchange account. 

Which [Exchange folders access account permissions][2] are required for this?

Would Reader permissions on that mailboxes and folders be enough?
