I Am Already Using Office 365 On The Cloud, Do I Still Need A Separate Email Archiving Solution?

There is a lot of chaos about archiving office 365 mailboxes. Here is what you should consider for archiving your office 365 mailboxes.

Is moving to cloud email good?

With the continuous increase in usage of emails for almost all business conversations, moving to cloud is just a matter of time. It is no longer a question of ‘should you move to cloud’, but rather about ‘when’. We have been consistently speaking about the benefits to the customer of moving from an on premise setup to a cloud email service. Customers moving to a cloud email platform like SkyConnect, Office 365, Google’s G Suite etc., are free from the relentless work required to keep an on premise mail setup running.

It frees you from stressing about infrastructure issues, software upgrades, planning and provisioning for disaster, security, data backup, manpower and more.

But, office 365 Cloud Email and its ilk may not be a panacea for all ills

While office 356’s cloud mail solutions covers a lot of ground, customers of cloud email services we’ve spoken to, have expressed concerns about the inbuilt archiving system.

Concerns regarding the features not being easy to use or not doing enough to meet compliance needs, and having limited eDiscovery capabilities.

In addition, difficulties in extracting large volumes of data are challenging, with not enough protection from loss of email data; either malicious removal or accidental loss only adds to the woes. Increasing regulation, incidences of litigation, and operational needs, further fuel these concerns. Thus, making it necessary to have immutable storage of email data, along with speedy, accurate and complete access to it.

As you decide moving your emails to the cloud, it is essential to remember that it is your data and you should consider how to appropriately protect and exercise control over your data. The responsibility of safeguarding your data ultimately is yours. But what are the best ways to be sure of being protected? Here is a guide that will help you know 7 things you should consider for your office 365 cloud email archiving needs.

1. Is your email data immutable by default?

A copy of every mail sent and received should be automatically captured and stored by default. An archive store of a cloud email archiving solution, by default should be immutable and secured by strong access rights. This ensures that the data cannot be deleted, until the retention period ends. The most suitable cloud email archiving solution, will store an independent and separate copy of all the email data in a facility outside of the operational cloud email infrastructure.

Let’s understand why the ‘legal-hold’ feature offered by some cloud email services in not enough. The inbuilt archive system providing a legal-hold option is an ‘in place archive, providing just another view of the existing mailbox. They are not separate copies of the email. This means that the Legal Hold option, when switched ‘ON’ for certain users, is simply meant to preserve data for a period of time (to probably handle an investigation or legal case that is ongoing or may come-up during a fixed duration) and is not really meant to be a long term immutable archive store. The litigation or legal hold is not automatically deployed on mailboxes. It is a conscious decision on the part of the management to switch this on for certain users. Mailboxes not on hold, can be tampered with.

2. Is your email data easily retrievable?

Consider this: You accidentally deleted some or all of your mail (or your account was hacked deleting all emails).

The most suitable archive platform for such a scenario, is to have all your data in an immutable archive store, irrespective of what has transpired on the primary mailbox. It will also allow you to retrieve all the stored data so you can rebuild your primary mailbox. Being able to do so easily is a great productivity booster. If the same level of recoverability has to be achieved with the in-place archive feature, then mailboxes will have to be put on legal hold from the start. A side effect of this would be that a user would not be able to delete any mail, leading to bloated primary mailboxes. Needless to say, this is a productivity killer.

3. Can you run deep searches and analysis across mailboxes without hampering the performance of your primary platform?

There is an explosion in the storage required by enterprises towards meeting stricter regulations and to provide historical data in case of disputes & litigation. Generally companies maintain a typical period of 7+ years, over which the historical data must be maintained. The growth in mailboxes sizes can severely compromise productivity, due to difficulties in locating relevant information. A cloud email archiving solution such as Vaultastic, creating separate copies of the mail exchanges, can help reduce the size on the primary or active mail boxes. Vaultastic helps by archiving Office 365 mailboxes, and providing for an immutable, long term and high durability store of all the historical data for recovery, compliance and eDiscovery. Searches, analysis, data movement can be more freely executed on the copy of the mail box, without causing disruption or impacting performance of the active mailbox.

4. How difficult is it to serve request for Historical data? Does your system offer a DIY interface?

Employees are increasingly using Office 365 cloud email and the like as their primary mechanism to share and access important information. IDC says 60% of business critical information is stored, sometimes exclusively, in Email. While, Gartner estimates that by 2019, 75% of organizations will treat archive data, including email, as an active data source. A quick analysis of our helpdesk for our cloud email service, shows that a good number of requests relate to locating and/or recovering historical mail (a few mails or the entire mailbox). This can severely load the enterprise IT team if, the archive system is not equipping users with a self-service feature to search through their own archive store and recover their own mail.

5. Do you have an option to maintain the historical data of employees who are no longer with you?

In most cloud email platforms, if an employee leaves your organization, you have two options to maintain their information.

a. Download all their mail and store it in a local archive, and then delete the user.
b. Deactivate the user, deploy a legal hold and maintain the information on the primary email platform.

The problems with (a) are the same as storing data in premise – ensuring safety, security and accessibility over time. The problems with (b) are the cost of maintaining an inactive account (often similar to the cost of a live mailbox).

A cloud email archiving solution such as Vaultastic allows you to pack off the data of inactive users, into an inactive archive. In addition, Vaulastic provides guaranteed availability at a reduced price, to be used on demand for knowledge discovery, analysis etc.

6. Is your email archive data getting splintered?

Consider this: When companies grow through acquisition and mergers, it may find the individual companies in the group using different email systems. One could be Archiving office 365 mailboxes, the other could be on the G Suite platform without any archiving. Consolidating all the mailboxes onto one platform can be very challenging and disruptive. It would be easier to have all the email data from disparate email platforms, archived to one central archive store, thereby bringing greater control and preparing the grounds for future mailing system consolidation. You now have access to the entire information via a uniform, standard interface and can comfortably service compliance, recovery or discovery requests. All this without working your way through the vagaries of so many platforms and fragmented data.

7. Are you locked into your email vendor?

A cloud email solution offers an inline archive, where it stores primary and archived mailboxes in the same single environment. Thus making it more difficult to switch to another email environment or use tools offered by others – essentially leading to a vendor lock-in. Getting data IN is quite easy and builds up over time, but when you need to change your mail platform, you need to extract all the information in a short span of time, which makes it very challenging. Therefore storing archived email data in a separate platform and location, supports not just compliance and regulatory requirements, but also frees you from getting locked-in to a particular mail platform.


In conclusion, migrating your email to the cloud is a good move, covering a lot of ground. However, businesses will need to purchase a third party cloud email archiving solution to offset the shortfalls outlined above and create a stronger solution.

To recap, ensure that the email archiving solution you choose:

a. Stores the email data in a separate immutable store

b. Gives control to the owner of the data with easy data extraction on demand
