We have a mailbox and an archive folder for each user. Mailbox and archive mailbox are stored on separate servers, but when a user logs in to his email, he can see the Archive folder, and all the emails sent and received are stored.

User has no access to remove the contents of the Archive folder.

But few users have removed the Entire Archive folder, and now they are not able to find it back.

How can i bring the Archive folder back on the folder list?

When i login to the Administrative page, i can see the Archive emails and all the contents.

Help appreciated.
