In addition to my previous blog article Office 365 & Exchange Online Archiving, here are the details of how to do this task in Office 365 portal for online users.
After the migration from Exchange on-premises server to cloud solution, the options are available for global administrator to activate it. Also it depends on the plan from O365.
The default quota size for an archive mailbox depends on the type of user license assigned to the mailbox.
How online Archive mailboxes help mitigate common issues?
You can log on the Office 365 Portal to create an archive mailbox for a user’s primary cloud-based mailbox. Users can use the archive mailbox, also called a personal archive, to store historical messaging data by moving or copying messages from their primary mailbox to their archive mailbox.
The archived messages reside in the cloud, and users can access it from any computer using Microsoft Outlook 2010 or Outlook Web App.
Steps below for how to enable the archive mailbox for Office365:
Caution When you disable an archive mailbox, the contents of the archive are permanently removed. The archive won’t be accessible by the user and you can’t reconnect the archive mailbox to the corresponding primary mailbox.
If you enable the archive mailbox after disabling it, a new archive mailbox is created, and it won’t contain the contents from the previous archive.
Enable archive mailboxes for all users in your organization by using Windows PowerShell.
In my previous blog, which mentioned how to connect Office 365 Powershell utility from on-prem to cloud to do the PS task.
To enable an archive mailbox for all users in your organization, run the following command:
Get-Mailbox -ResultSize unlimited -Filter {(RecipientTypeDetails -eq 'UserMailbox')} | Enable-Mailbox -Archive When you run this command, the archive mailbox name is set to “Online Archive – <display name>” by default.
After you enable the archive mailbox for a user’s primary mailbox, you can change the name of the archive mailbox if necessary.
The next time the user accesses their mailbox, the new name for the archive mailbox is displayed under the folder list in the left pane of Microsoft Outlook 2010 or Outlook Web App.
