Office 365 Online Archive

Abdul Aziz 1 Reputation point

one of my user mailbox in office 365 with E3 License has reached 85GB of mailbox size out of 100GB.

i want to enable the online archive mailbox, does E3 is sufficient for enabling the archive mailbox option.?

also i want to know how to create the policy for specific user to move his email from primary inbox to Online archive mailbox by using policy ( retention). does it move folder as well once the policy is applied ? please provide the steps to do the policy.

Thank you

    Yes, E3 is sufficient, go ahead and enable the Online Archive. Once you do this, the default retention policy will kick in and start moving every message older than 2 years to the archive. If you want to customize the settings of the default policy or apply a different one, refer to the documentation for step-by-step instructions:

    Hi @Abdul Aziz

    E3 license supports for online archive, please refer to the limits for different licenses here:
    Storage limits

    We could create rentention tags firstly (which is used to specify how long a message remains in a mailbox and the action to be taken when the message reaches the specified retention age. When a message reaches its retention age, it's moved to the user's In-Place Archive or deleted.)

    Then you add the tags to the policy and apply the policy to the user.

    New-RetentionPolicy "RetentionPolicy-Corp"  -RetentionPolicyTagLinks "DPT-Corp-Delete","DPT-Corp-Move","DPT-Corp-Voicemail","RPT-Corp-JunkMail","Never Delete"  
    Set-Mailbox "Morris" -RetentionPolicy "RP-Finance"  

    To make the policy take effect:

    Start-ManagedFolderAssistant -Identity "<Mailbox Identity>"  

    The complete process is like below:

    And refer to the introduction of different Types of retention tags
