Auto-Expanding Online Archive Office 365

This week I had to check the “Auto-Expanding” archiving feature in office 365, after reading and implementing this, turns out that it is really a good one, this features provides additional storage space for our archive mailboxes – how are you asking? – follow me:

Usually, a user gets 100 GB of storage for archiving, when a mailbox capacity is reached, auto-expanding will add automatically additional storage, Office 365 automatically adds storage space to the archive when necessary, another important point it’s that auto-expanding adds additional space for shared mailboxes as well.

Actually, folders moved as a new subfolder on your archive folder; the funny thing is that Microsoft Office 365 decides which folder get moved when auto-expanding is added.

In order to enable this feature for a user, you have to be a member of “Global Administrator” or “Organization Management“.

Once you turned on auto-expanding archiving for your mailbox it can take up to 60 days for getting the additional storage.
BTW, almost forget to state – you cannot turn off auto-expanding as soon as you turn on it.

Before you turn on the “Auto-Expanding ” ensure you have enabled the archiving option to the user.

Get-Mailbox -Filter {ArchiveStatus -Eq "None" -AND RecipientTypeDetails -eq "UserMailbox"} | Enable-Mailbox -Archive

How to enable Auto-Expanding for your organization?

Maybe have you already enabled it? Check it out:

Microsoft says that only “Outlook 2016 for Windows, Mac, and OWA” are possible for accessing in the auto-expanded archive.
