Do you know what is currently the largest size this can *actually* grow to, when you're supposed to have "unlimited" archiving? I ran into this issue with my family member's Exchange Online Plan 2 over a year ago. Your sample screenshot showed an Online Archive mailbox provisioned at 100GB. Get-Mailbox | Set-mailbox -RetentionPolicy policy-name To set a specific retention policy for all mailboxes, use Set-Mailbox -Identity -RetentionPolicy policy-name To apply a specific retention policy to a specific mailbox, use When archive is enabled, the default retention policy is applied to the mailbox. Get-Mailbox -ResultSize unlimited -Filter | Enable-Mailbox –Archive To enable the archive only on usermailboxes, use To set all mailboxes to use the online archive, use this format: You can of course do the same thing with PowerShell, using the enable-mailbox command: Using PowerShell to enable Online Archive Remember, this options vary depending on the Exchange Online plan the mailbox is subscribed for. Selecting that will show you a window providing details of the mailbox. Users can drag and drop items into the archive folders and email policies (user and organizational) can now utilize that folder.Īs an administrator, if you again look at the mailbox, under in-place archive you will see an option View Details. You can enable the in-place archive using the Exchange admin portal or using PowerShell. With Exchange Plan 1 the total size of the Inbox combined with the in-place archive cannot exceed 50GB. For example, in Exchange Online Plan 1 you could have a 25GB Inbox and a 25GB Archive, or a 10GB Inbox and 40GB archive.
Plans that have Exchange Online Plan 1 (Business, and E1) have a current limit of 50GB of storage between the Inbox and the Archive. Plans that include Exchange Online Plan 2 (E3, E4) have an unlimited archive.Other versions of Outlook will not display the archive folders even though they may be present and enabled.
