Introduction

Office 365 retention policies can be used to automatically delete e-mail older than a specified time. Default retention policies (which can't be modified by users) are applied against the "Deleted Items" and "Junk Mail" folders to automatically remove items older than 30 days from each folder. No other folders have retention policies applied by default but users may choose to apply personal retention policies to automatically delete e-mail from non-system folders (i.e. all folders except Inbox, Sent Items, Drafts, Deleted Items, and Junk Mail) after a set time period, such as 6 months, 1 year, 5 years, etc. Note that policies may take up to a week to begin applying.

Please refer to the instructions below to add retention policies to a non-default e-mail folder.
