Mail retention policy for Archive M365 Data Lifecycle Management
Hi,
I want to apply an email retention policy such that, the emails in the mailbox are retained for 3 years and get deleted and the mail in the archive is there for 5 years and get deleted.
Now, I have enabled a retention policy through Data lifecycle management-> Microsoft 365.
The policy will retain emails for 3 years and after that, the emails will be deleted.
But, the issue is that this policy is being applied to the archive as well and I want to exclude the archive so that the archive will have a different policy- email retention for 5 years, could someone please suggest how to achieve that using Data lifecycle management-> Microsoft 365?
This is what the policy looks like in my archive email:
Hi newtotechcom-J,
no problem 🙂
Exclusion of users from retention policies can be accomplished using the Set-RetentionCompliancePolicy cmdlet.
This cmdlet provides the capability to modify existing retention policies by adding or removing specific locations, such as user mailboxes:Set-RetentionCompliancePolicy -Identity "YourPolicyName" -RemoveExchangeLocation "email address removed for privacy reasons"​<br />The above command is designed to eliminate the mailbox of the email address removed for privacy reasons from the retention policy named YourPolicyName.<br /><br />Set-RetentionCompliancePolicy (ExchangePowerShell) | Microsoft Learn<br /><br />As for when to exclude users, it’s generally more efficient to exclude them before making the custom policy default. This way, you ensure that the policy is correctly configured before it’s applied to all users.<br />

Hi newtotechcom-J,
in Microsoft 365, you can apply different retention policies to the mailbox and the archive.
However, it’s important to note that the same retention policy is applied to the primary and archive mailbox.To apply a different retention policy to the archive, you can use the Move to Archive action in your retention tags. This action moves items to the archive mailbox after a specified period of time. Please note that the Move to Archive action must have a lower retention age than the Delete action.
Applying Retention Policies to Archive Mailboxes - Microsoft Communityhere are the steps for configuring archive and deletion policies for mailboxes:
Activate Archive Mailboxes for Users: Ensure that each user in your organization has an archive mailbox.
Generate New Retention Tags for Archive and Deletion Policies: Retention tags specify the duration a message stays in the mailbox and the action taken when it reaches the specified retention age.
Formulate a New Retention Policy: This policy transfers items to a user's archive mailbox after a designated period and also removes items from the Deleted Items folder once they surpass a specific age limit.
Assign the New Retention Policy to User Mailboxes: A retention tag applies retention settings to individual messages and folders in a user's mailbox.
It's important to note that the actual rules governing the movement or deletion of items and the timing of these actions are defined by retention tags.
Retention tags are associated with an MRM retention policy, which is then assigned to a user's mailbox. When a message reaches its retention age, it is either moved to the user's archive mailbox or deleted.

(LinkedIn)Hi LeonPavesic
I have created a retention policy, but I can see that there is an existing default MRM policy.
How can I enforce this my retention policy to all users instead of default MRM policy?Hi newtotechcom-J,
thanks for your update and your question regarding assigning your custom retention policy for all your users.
To do that you can follow these steps:Sign in to the new Exchange admin center (https://admin.exchange.microsoft.com), and go to Mailboxes.
