Exporting Emails from Office 365 and Exchange Mailbox Purges folder using EWS managed API

Plenty of times users reports missing email issues, you have them check deleted items folder, and recover deleted items folders, but the items are not there, now you check mailbox stats and see there are items in purges folders, as Purges is hidden from the outlook view you can access it from outlook, though you can use the MFCMapi to access the purges folder, but that is pretty time-consuming job for a person like me, I would rather prefer spending twice the in building the script, them doing the job manually using the GUI based tool.

This script give you power to report the emails in Deletions (Recoverable Items folder) and Purges folder, you can export and share the report with user to review if the missing emails are then and then if you wish you can export the emails in ".eml" format and share the same with user or you can import emails into user mailbox.

Please check my script on importing email into user Mailbox using EWS managed API below.

As we are going to use the EWS make sure you met all the prerequisites before you plan to run this script.

• Admin account should have application impersonation rights, you can follow this msdn post to setup the permissions.
• Install EWS managed API on system where you plan to run the script from, if API is not installed, download the same from here

Note: Please install the latest version of EWS API, version 2.2 is currently being used in my script.
