Online Archiving in Office365


If you are a user of Email, chances are that you are aware of the concept of archiving. What it really means is that in order to ensure that our mailbox remains within the specified limit, we remove the mails from our mailbox and store the same as a backup usually in the form of a .PST file. In many cases, this process is automated whereby a user specifies that any mail beyond, say, 6 months should be archived and the PST file is then stored on his PC or on the Server.

This method is widely used. But it has certain flaws:


1) If the PST is stored in the local computer and the hard disk fails, chances are that PST will be lost along with data


2) If the Admin makes a global search , the mails in the PST will not be searched. So compliance and e discovery suffers.


3) The data in the PST is available only from the Outlook of the user . If the user were to login on a different PC, then this data is not available.



To overcome these issues and to better manage the mail backup, there is a very useful feature available in Office365, called Online Archive. Administrators can provision it for the users. And then the users can see the Archive mailbox along with the actual mailbox in Outlook as well as in Outlook Web Access – OWA.


Note that the total mailbox size remains 50 GB. It just gets divided into 2 : main mailbox and archive mailbox.



1) The PST is stored Online . So even if local hard disk fails, the PST is safe in the Microsoft Datacentre.


2) Since it is stored in the Cloud, the Admin can make global search which can even search for mails inside PST


3) As the PST is Online, it is available from any PC and not just from the PC of the User
