Export Entire Outlook Mailbox to PST file

[SamPo]

Hi All,

I'm wondering if it's possible to initiate a backup of an entire 365 mailbox to a PST file. Currently we do this directly from the 365 server using the built in backup tool.

Use case: When an employee leaves the company we backup their entire mailbox before deleting their account.

Was thinking this could be done with UI Flows but wondering if there's a way to do it via API.

Anyone have an ideas or experience with this?

Thanks,

Sam

Hi @SamPo 

Exporting an entire mailbox is currently not supported as a direct action in Power Automate. (You could export individual email though but still there is a limit on the number of emails that you can get using the get email action and export email action)

If you think this should be added as a feature/ function, you can create an idea post here or upvote already existing similar ones. https://powerusers.microsoft.com/t5/Power-Automate-Ideas/idb-p/FlowIdeas

Hope this Helps!

Going with an Office 365 backup tool is the best solution to converting Outlook mailbox to PST. This tool helps to bulk migrate office 365 emails and does not alter a single data during the conversion. I am a frequent user of this tool and this tool easily migrates the office 365 emails with accuracy. The Office 365 backup tool for Mac enables migrating/converting Office 365 emails to 20+ various file formats and email clients. You can opt to migrate only selective emails using the Date Range Filter of this tool.
