o365 Limit How Long User can Retain Emails For

Question

In office 365 is there a way to limit how long a user can retain emails for? If not, can a policy be created to purge users recycling bin every week?

Hi，

Thanks for posting your question in the Microsoft Q&A forum.

First, you must be a global administrator because only global administrators can create retention policies.

Hopefully the steps below will help:

1. Sign in to the Microsoft Purview compliance portal and navigate to Solutions > Data lifecycle management > Exchange (legacy) 
2. You can set up a new Retention Tag to suit your needs.
3. If you want to delete emails that have been in the user's recycle bin for more than 7 days, you can choose Automatically to default folder.
4. Then, select RETENTION POLICY and click +. Fill in the name of the retention policy and select the tag you just created. Finally, click submit
5. Sign in to the EAC and navigate to Recipients > Mailboxes.
6. In the list view, select the mailbox to which you want to apply the retention policy.
7. In the details panes for that mailbox, select Mailbox, and then for the Retention policy section, select Manage mailbox policies.
8. In the Mailbox policies pane, use the dropdown list box for Retention policy to select the policy you want to apply to the mailbox, and then select Save.

If my answer is helpful to you, could you please mark it as an answer for reference for people with the same problem?
