Released: Hybrid Organization Configuration Transfer V2

Exchange Team Blog -

We are happy to announce Organization Configuration Transfer (OCT) - V2, which includes updates to OCT-Phase 1 that was launched earlier this year. OCT-V2 further reduces the manual work that admins are required to do once the hybrid setup is complete. OCT-V2 is now available as part of the Hybrid Configuration Wizard (HCW).

What does OCT-V2 include?

OCT-V2 not only copies the organization policy objects from on-premises to Exchange Online (EXO), but also updates the values in EXO with the values from on-premises. Seven additional objects have been added to OCT as part of V2. The list of objects considered in OCT so far are:

OCT (available since June 2018)
  • Active Sync Mailbox Policy
  • Mobile Device Mailbox Policy
  • OWA Mailbox Policy
  • Retention Policy
  • Retention Policy Tag
OCT-V2 (available now)
  • Active Sync Device Access Rule
  • Active Sync Organization Settings
  • Address List
  • DLP Policy
  • Malware Filter Policy
  • Organization Config
  • Policy Tip Config

If object values are updated on-premises after they are moved to EXO, admins can re-run OCT to copy over the updated values from on-premises to EXO. Admins will continue to control the process of keeping the objects in sync but with reduced effort by using OCT.

How is V2 different from the initial version of OCT that was launched in June 2018?

Phase 1 of OCT dealt only with copying objects from on-premises to EXO. However, it did not edit/update the parameters in EXO. As part of V2, if an object with the same name already exists in both on-premises and EXO, admins can now choose to either overwrite the values of the objects in EXO or keep them as is. A rollback script with values of the objects prior to the update in EXO will be available to admins in the log folder.

What are the Exchange Server Versions supported?

The supported versions are Exchange Server 2019, 2016, 2013 and 2010. OCT-V2 requires the latest cumulative update or update roll-up available for the version of Exchange you have installed in the on-premises organization. If you cannot install the latest cumulative update or update roll-up, the immediate previous release is also supported. Older cumulative updates or update roll-ups are not supported.

Announcing support to migrate up to 250K public folders from Exchange On-Premises to Exchange Online

Exchange Team Blog -

In an earlier post, we announced we were increasing the maximum number of public folders that could be migrated from Exchange Server 2010 to Exchange Online to 250K. We also highlighted in that post that the migration of public folders on Exchange Server 2013 and 2016 were limited to 100K.

We’ve been working hard to remove this limitation and we are very pleased to announce today that we now support migrating up to 250K public folders from Exchange On-Premises 2013/2016/2019 to Exchange Online.

What does all this mean to you?
  • Any Exchange On-Premises customer running Exchange 2010/2013/2016/2019 with up to 250K public folders can now migrate them directly to Exchange Online.

Please do check this link for planning migration of public folders to Exchange Online. The current Exchange Online limits can be viewed here.

We’ve love to hear your feedback and please feel free to ask any questions via the comments section below.
