You do not need permissions to perform the import process through the Desktop Outlook Application. But if you are to perform the process through Exchange Management Shell, then you need to provide the permission to perform Import process. For that execute the following command
New-ManagementRoleAssignment –Role “Mailbox Import Export” –User {username}
In the above command, username stands for user asking for Import permission.
For Ex: New-ManagementRoleAssignment –Role “Mailbox Import Export” –User Administrator
Then, for Import, execute the below command
New-MailboxImportRequest -Mailbox “User_Mailbox_Name” -FilePath “UNC_shared_File_Path”
Note: User_Mailbox_Name is the name of the User mailbox to whom the resultant PST file will be imported to. UNC shared File Path is different from the Normal File Path. If you don't know how to create UNC shared File Path, Refer: Creating UNC shared file path for a PST file
