What is Email Archiving with Office 365?

Office365 provides features and functionality that many users of on-premise Exchange email systems will be familiar with, such as the reminder to ‘archive your old items’ that Outlook suggests, especially when mailbox storage limits are approached.  

Like on-premise Exchange, Office365 permits old copies of email to be moved from a user’s live mailbox to an archive.

Office 365 email archiving services offer this in three ways: the recoverable folders structure, the ability to export to .pstfiles and the use of legal hold.

Why do Office 365 Customers Need 3rd Party Email Archiving?

A 3rd party email archiving solution is essential with Office 365 to easily access and retrieve data for compliance purposes. There are many useful features of Microsoft Office 365, but the email archiving tool has been scrutinised and has let customers down. A supporting email archiving tool such as ArcTitan can ensure Office 365 Customers can archive emails efficiently and securely.

Email archiving has become an essential function within modern organisations, it’s not enough to simply store your messages, they need to be easily searched and retrieved for compliance.

Office 365 can search through approximately 50 different attachment file types (mostly Microsoft files), but there are hundreds of other potential files that Office 365 can’t interrogate. Office 365 permits only 50GB of email storage capacity (including your archive), meaning you can quickly run out of space.

Unfortunately, these inadequate features can expose businesses to litigation risk. If you can’t properly retain and search your emails, then you’re in danger of non-compliance with government regulations, which can result in substantial fines or even imprisonment.

Organisations require a better email archive solution – one that enables them to archive emails in a fully compliant and secure manner.

Advantages of Using O365 Email archiving solutions

Cloud-based email archiving is the quickly becoming a standard software for businesses using office 365 as their email service provider. By implementing an email security solution, businesses are given additional features that are not available in office 365. Features include:

Instant access & retrieval of files – it goes without saying that accessing emails in outlook is a time-consuming and frustrating process. Email archiving for office 365 solutions allow you to gain access to archived files instantly. Access and retrieval of archived emails within seconds, therefore, helps with employee productivity.

Compliance - ArcTitan, provides cloud-based archiving and retrieval of emails, compliant with Sarbanes–Oxley, HIPPA, and other regulations for eDiscovery, retention, and audit. Archived emails include an audit trail, documenting any modifications to messages, ensuring compliance to regulations.

eDiscovery for Data Management - an eDiscovery request can be instantly produced with an email archiving solution. If an organization is unable to produce emails/records that they are required to by the law or rule, it leads to fines and perhaps even criminal charges. Archiving emails doesn’t just assist a business in avoiding fines; it can provide a wealth of material for a business’s legal team in an easy-to-access format

Retention Policies - Email retention software sends emails, email attachments, contacts, tasks, calendars, and other email data to an archive, which is different from an email backup. With a solution like ArcTitan, admin users can set up automatic retention policies and rules.

Storage – an email archiving solution provides organisations with unlimited storage.
