Transfer events from user mailbox calendar to a shared mailbox calendar

Question

HI,

I created a shared mailbox and I want to transfer events from other users' calendars to the calendar of this shared mailbox. Is there a way to do this via PowerShell?

Hi, @abderrahmane belabes

If you're using Exchange Online, you can try Vasil Michev's suggestion.

If you are using Exchange Server, you can also try to use New-MailboxExportRequest and New-MailboxImportRequest to export calendar events from the user mailbox to a PST file and then import them to the shared mailbox.

You can create a PowerShell script that leverages the EWS API, or use this existing one: https://github.com/David-Barrett-MS/PowerShell-EWS-Scripts/wiki/Merge-MailboxFolders.ps1

Similarly, you can use a Graph-based script, although there is no support for cross-mailbox move operations within Graph. But you can fetch the item(s) in question and all their properties, then create matching items within the shared mailbox.
