A flexible and quick way to migrate all emails, contacts, tasks, and other data from a third-party hosted and managed Exchange Server to Office 365 Exchange Online.

    This service allows you to migrate from an Exchange Server to Exchange Online if you do not have direct administrative access to the server. Migration is possible using the credentials of each user.

    This migration occurs in the cutover migration mode when all information from mailboxes is immediately transferred to a new location.

    During MX record switching, the email service may be unavailable. The downtime depends on the DNS settings of your provider and the DNS system features of email senders.

    You can also use the additional email caching service, which will allow you to receive all emails regardless of the MX switching duration.
