1and1 IMAP migration onto Office365 RRS feed

  • Question

  • We have 1and1 IMAP acount with 200 users and setup Office 365 migration batch for pilot users. I have some questions and concerns about staged migration from 1and1 to Office 365.

    1. As we are not migrating all users, is there anyway migrated users incoming mails can be forwarded from 1and1 to Office 365 till we cahnge MX record for mailflow?

    I have followed below link, but not working for 1and1.


    1. Can we migrate users in batches and schedule continuous batch sync in office 365, so that users no need to login to 1and1 and start using office 365? I don't find any source to run migration batches continuouly or scheuled intervals like every 10 minutes.


    3. Is there anyway we can use 1and1 admin account credentials and migrate user mailboxes without using user password in 1and1?

    Thanks in advance for your help.
