Archive Migration to Office 365

How can TransVault Help With Move to Office 365?

The first migration solution to be certified by Microsoft for email archive migrations, and available from global network of TransVault Certified Migration Masters, including Microsoft Global Services, TransVault™ quickly and securely migrates legacy archived email into Office 365 or, indeed, back into Exchange.

Your archives are moved in 1 step, direct from the source archive into Office 365 using banking-style transactions over EWS.

There’s no need to convert emails into an interim format (such as PSTs) and no need for ‘pre-staging’ or manual intervention, massively speeding up migration times and eliminating risk.

What are the issues with migrating single-instanced journals into Office 365 mailboxes?

Apart from the issues surrounding large mailboxes in Office 365 (which arguably are decreasing), putting all your compliance emails in one or more Office 365 mailboxes creates additional problems that you should be aware of:

  1. It breaks Microsoft’s licensing rules.  Microsoft states that using a single In-Place Archive as a means to store mail from multiple users or entities is prohibitedhttps://technet.microsoft.com/en-GB/library/exchange-online-limits.aspx. Microsoft defines its product warranty and scopes the functionality of future products based on its product licensing.  By bulk-moving multiple users’ email records into a one or more mailboxes (e.g. one mailbox each year) you could end up in a scenario where Microsoft isn’t able to support your journal data because you’ve contravened Office 365 usage rules.
  2. You risk incomplete eDiscovery searches. The Microsoft eDiscovery model works on the basis of searching one or more specified mailboxes.  If, as part of a journal migration you combined multiple users’ emails into one or more mailboxes, it is vital that these ‘non-standard’ mailboxes are included in any future eDiscovery exercise.  Bearing in mind that searches may take place many years hence, and that eDiscovery may be carried out by Compliance Officers, HR personnel, etc., that may not be aware of this ‘historic IT workaround’– it is easy to see how legacy journal mailboxes may inadvertently be excluded from an investigation, risking incomplete results.
  3. Your data becomes difficult to manage in the future.   With multiple users’ email held in one or more ‘single buckets’ it becomes difficult to apply policies for records management on anything other than a date basis.  For example, in the event of a divestiture, it is not uncommon for users’ data to be separated as different operational units break away.  By maintaining users’ data in individual mailboxes this process becomes easier. Your organisation will also have a clearer view of all the past employees or ‘leavers’ when their data needs to be managed or included in a search.  This visibility is easily lost when historic email records are kept in one mailbox.
