Message size limit:

·         A message (including attachments if any) that exceeds the maximum message size (35 MB by default) will be skipped during the migration.

Migration of mailboxes from Zimbra 6 and 7 is not supported anymore.

Release (05/24/2017)


The consumption of ODME resources was reduced for better scalability.

This enhancement was implemented to optimize the content of processing flow. As a result, the consumption of ODME resources per migrated mailbox has been decreased for the benefits of scalability.

Release (05/22/2017)


The volume of Azure storage that is used to facilitate gathering of migration statistics has been minimized. This lets you avoid excessive utilization of ODME resources in case of migration of extra-large mailboxes.

All supported migration scenarios.

ODME has the mechanism that facilitates gathering of migration statistics. This mechanism has the deficiency: excessive volume of Azure storage is consumed in case of migration of extra-large mailboxes. This deficiency leads to scalability issues that cause the migration slowdown.


For all supported migration scenarios, ODME internal application settings were aligned with Microsoft Azure best practices to ensure the best migration performance and scalability:

·         ODME application settings are set to process concurrent user requests

·         The Nagle’s algorithm that has a negative performance impact is turned off


Scope: Migration from G Suite to Exchange 2010, 2013 or 2016 and from Office 365 to Office 365

The migration performance has been increased up to 30 per cent by introducing multi-threaded upload operations.

Release (05/16/2017)


In order to allow connectivity to the source and target email service, it is required to ensure that your firewall is opened for the IP addresses used by ODME. The list of IP addresses in the About box from the ODME home page now includes only the product deployments for the current Azure region. So, the region cannot be changed once the customer account is registered.


Overall responsiveness of the ODME portal has been improved.

Release (04/28/2017)


Migration rescheduling strategy is improved for migrations from G Suite:
Once the size of migrated content has achieved the value of Gmail daily throttling limit, ODME pauses. The duration of this pause is calculated to ensure that the migrated content size for the last 24 hours will not exceed Gmail daily throttling limit. This is especially beneficial for migration of extra-large mailboxes.

Release (04/25/2017)


ODME deployments now include Azure cloud data center in Australia.

Release (04/21/2017)


As for migration from G Suite, the overall migration rate has been improved due to change of the message extracting protocol from IMAP to GMAIL API. Therefore daily limit for the amount of data you can extract from your G Suite source during a migration has been safely increased from 2.2GB to 10GB.

The new value will be applied to all newly created plans by default. In order to safely apply the new value to an existing plan, you need to stop the plan and update this value manually.

For details refer to Managing Google Throttling.
