Migrating to Microsoft Office 365

Thousands of organizations are making the move to Microsoft Office 365. Office 365 replaces on premise Microsoft Exchange and offers a bundle of cloud services including messaging, calendaring, instant messaging, social collaboration, file sync/share and more.

Many organizations considering a migration to Office 365 have previously relied on a third party product to archive their users’ email. Today, they have terabytes of archived mail that include different data types:

  • Email messages, for both active and inactive users
  • Stubs or shortcuts
  • PSTs
  • Message journals

What Happens To Your Archive When You Migrate To Office 365?

Get ready for some angry end users and legal team, as well as an overloaded Help Desk!

Most archiving products do not work, or at least work well, with Office 365. When you move your users’ mailboxes to the cloud, you break the message stubs or shortcuts, so users can no longer access those archived messages.

Journaling for compliance and e-discovery will not work once you migrate; you are no longer in compliance with internal policies or external regulations. Workarounds do exist for some tools, but they almost eliminate many of the reasons for migrating to Office 365.

What about PST Files?

One of the greatest issues in most Office 365 migrations is PSTs. Traditional migration methods do not validate the integrity of the messages, or the existence and number of stubs.

Key Email Archive Migration Concerns

If you are planning an Office 365 email archive migration and have a third party or legacy email archiving product, you need to address the following as part of your migration project:

  • Do I want to continue using my third party archiving product once I migrate to Office 365?
  • How will my users be affected if I do not migrate their archived mail?
  • How will my users be affected if I delete MS Exchange stubs/shortcuts?
  • How much data do I have in my third party archive?
  • What kind of data is it (mail, stubs, PSTs, journals)?
  • How much email do I have in the journal archive?
  • How much “dark data” do I have (archived messages from inactive users)?
  • Is the data of any value to my organization?
  • If I have ongoing or pending litigation; can I still migrate my mail?
  • How do I manage archived email that is under legal hold?
  • Assuming I decide to migrate my archived email, should I migrate the entire archive and journal archive?
  • Will migrating my archive delay my Office 365 implementation project?
