shino tomoka customer review for zimbra migration

Shino Tomoka

Outlook 365

Osaka - Japan

Migration from Zimbra to Office 365 has been successfully performed. I had to migrate only selected emails from certain years such as 2018, 2021, 2024, and some of the emails of the current year 2026, besides contacts and Briefcase. Since I did not need to migrate any other emails from other years, filtering and ignoring unnecessary emails consumed some additional time. Nevertheless, the migration has been successfully carried out and I have transferred all the necessary data to Office 365. Zimbra kara ofisu 365 e no saitekina ikō o arigatōgozaimashita

The use of KDETools Zimbra to Office 365 Converter made the whole process easier and more automated. The customer support was there to help us with all the necessary actions.
