I do not think there is an EASY, right click -> export to PST for a mailbox, if you know of one, please let me know.
Since I can't find an easy way, I am going to attempt the code route.
I am looking to write some code to export an O365 mailbox to a .pst file. This is a local backup for when we want to keep the contents of an O365 mailbox after removing licenses.
After removing the O365 Licenses, the mailbox will stay for 30 days and then it is deleted.
I saw a post with a description about using Redemption which I have licensed, but there really is no detail on the process.
Microsoft Graph API to extract a .pst
I have access to the mailbox via EWS and would like to iterate through folders and then mail items in each folder.
Has anyone done anything with copying an O365 Mailbox offline to a .pst file?
