Public Folder to Office 365 Groups Migration Script

Earlier, I wrote on a new technet article that details migration to Office 365 groups from on prem public folders. Actually walking through that I noticed some inconveniences I figured I could improve on with a script. The main one being that the endpoint in Office 365 only supports a single Public Folder, excluding child folders.

So I wrote up a script (with resume support) that will map your Public Folders to O365 Groups and migrate them in as many batches as are required, fully automated.

You’ll end up with a nice csv file with all the details. Note:

  1. this script expects you to know what you’re doing!
  2. only tested with Exchange 2010 as source
  3. everything on prem is left untouched
  4. groups are not mail enabled, and security settings are not copied
  5. contacts are not copied

update 05/01: improved the connection status check + reconnect for remote ExO and fixed report file path auto generation

update 11/01: moved everything to start-job so exchange sessions are always isolated (no prompting after 1-2 days) and added total migration overview display 

Setting up Okta User -> Office 365 contact synchronisation

Okta natively does not allow you to sync users to Office 365 contacts; they either exist as users in Office 365, or they don’t exist at all.

In hybrid scenarios where you are doing a staged migration to Office 365, or where you simply manage your contacts in Okta, you may want to populate the Global Address List in Office 365 with your Okta users.

I’ve written a simple solution for this, you will require:

  1. Okta Admin Access (to obtain a token)
  2. Office 365 credentials (to write / modify Contacts)
  3. An Azure Subscription (for automation)

The solution will sync your users in Okta to Office 365, take note of the following: Continue reading Setting up Okta User -> Office 365 contact synchronisation
