One of my client want to migrate from "Linux Mail Server packaged BOX" to Office 365.
I'm OK with the migration of mail content (via IMAP / Supported by Microsoft).
My question is for Calendar & Contacts migration. Do you know how to do the import of this data on O365 (process or with a software) ?
Some information :
- Only webmail access to the source mail server (Linux)
- No Outlook installed on computers : users will only use OWA on O365
- Old server can only be accessed via IMAP
