Copy Contents From One Office 365 Mailbox to Another

Open powershell and connect to Exchange Online (see earlier post).

You can only copy the contents from the source mailbox into a folder on target mailbox. Use the following command –

Search-Mailbox source-id -TargetMailbox target-id -LogLevel full

You will be prompted to enter a folder name. Once you have entered the name the command will run. This will probably take several minutes and a small report will be displayed at the end.

Close the session to Exchange Online
