Move to O365 and Add PST files to outlook

[hntaurus]

Hello

we have an On Perm Exchange 2010 , we are planning to use O365 instead

we have 100 mailboxes and lest than 10 Public Folders.

In order to plan for migration , I was thinking to create users and O365 Groups(instead of Public Folders). and instead of uploading mailboxes and public folders , just export them to PST file and add them to each user's outlook so that they can see the old emails . and send/receive emails on their new mailbox. Now I was wondering if this solution makes sense and it would work?

@hntaurus It does make sense, although this migration method requires some manual work. You can export mailboxes to PST, using the New-MailboxExportRequest (here's more information about this method) and then use the Outlook import tool, or upload them to Azure storage.

Hey!

Your plan to switch to users and Office 365 Groups instead of Public Folders, and then moving old emails by exporting them to PST files for each user's Outlook, is really smart.

Adam Aardvark has already given a step-by-step guide to help you with the process. If you want any other methods on bringing in PST files to Office 365 or Microsoft 365, you can check out the blog post: https://the-tech-trend.com/gadgets/how-to-import-pst-to-office-365-or-microsoft-365/.

Hope this helps!
