• Incremental Migration support to avoid duplicates 

  EdbMails supports an incremental migration feature, ensuring that you can perform migration without duplicating data when running consecutive migrations from the same computer to the same target mailbox. This feature migrates only newly arrived emails from the source server to the destination, conserving time, bandwidth, and storage space on the target server. There are no restrictions on consecutive migration attempts

• Maximizing Migration Efficiency with Automated Throttling Control

  EdbMails automatic throttling management feature guarantees a seamless migration experience, enabling you to transfer all your data in a single task, even during peak usage hours on your Office 365 server. The software optimizes the migration process while expertly managing Microsoft's throttling protocols.

  EdbMails simplifies mailbox mapping by automatically mapping mailboxes between the source and target servers. All you need to do is select the 'Map Mailboxes Automatically' option in the mapping window. Additionally, there are options to manually map the source mailbox to a different target mailbox and map the source mailbox folder to a specific target mailbox folder.

• Zero Downtime throughout the migration

  EdbMails guarantees zero downtime during Office 365 migration, even when migration takes place during standard business hours. The migration process has no impact on email service availability. Users maintain access to their source mailboxes throughout the migration and can immediately resume work in the target Office 365 tenant once the migration completes.
