I’m working on an Office 365 migration where several users have separate archive mailboxes containing years of historical email data. Instead of handling each mailbox manually, I’m looking for a practical way to move multiple archive mailboxes to Office 365 while keeping the data properly organized.
The main challenge is the volume of information involved. Each archive mailbox may contain thousands of emails and attachments, and some users have much larger archives than others. Manually exporting and importing them one at a time seems like it could take a lot of time and also make it harder to keep track of which mailboxes have already been processed.
I’m particularly interested in maintaining the existing folder hierarchy during the migration. It would also be helpful if the process could preserve important mailbox information and attachments rather than simply transferring the email content. Another concern is duplicate data. If messages already exist in the destination mailbox, I’d prefer to avoid creating unnecessary copies.
Date-based filtering could also make the migration easier. For example, instead of moving every message from an archive, administrators could migrate specific periods first and then handle the remaining data separately. A migration report showing successful, skipped, or failed items would also be useful when dealing with multiple mailboxes.
I’ve been researching different approaches and came across the option to migrate archive mailbox to Office 365 using software rather than performing every transfer manually. I’m still comparing the available methods because I want something that can handle multiple mailboxes without making the process difficult to monitor.
One tool I’m currently looking into is the SysInfo Office 365 to PST Export Tool. I’m interested in understanding how it handles Archive, Primary, Shared, and Public mailbox data, particularly when administrators need to process a large amount of information and maintain the existing mailbox structure.
For those who have managed multiple archive mailbox migrations, how did you approach the process? Did you migrate the mailboxes individually, use date filters, or handle several archives together? I’d also appreciate any advice on tracking skipped and failed items during a large Office 365 migration.
