Hello everyone,
I am planning on migrating 150 mailbox from Linux, postfix to Office 365.
I was wondering if anyone has experience in this field:
1. Can I use this solution (IMAP to office 365)?

2. I also thought about exporting mailboxes to PST then switch MX to office 365, linking each account to office 365 using Outlook then importing PST indivually I know it sounds silly and long process but is it an option?
3. Is there any other options?
4. Are there any limitations which I should consider before starting this process i.e. size of mailbox, length of username, downtime etc?
