The PST file used to import must have the same name as the Exchange Alias of the account to be imported
The Mailboxes section that will be imported into the pst file must exist
To continue, we need to download and install the Outlook 2010 version here.
As recommended by many experienced users, experts are advised to set up a group - the group used to assign the role and then add user accounts to this group. In case you have created a group, it must be Universal Security Group, then use the following command from Exchange Management Shell:
New-ManagementRoleAssignment –Name 'MailboxImportExport' –SecurityGroup 'your_group_name "- Role' Mailbox Import Export '
At this point, we will assign the user account to import the PST file to the newly created group, then close the Exchange Management Console / Shell section , log - off and log - on again to apply the changes. . Technically, there are several ways to import PST files, which can be done in turn or all. As recommended, you should follow the simple way first (in turn), after everything is stable and sure, it will switch to all after mode. The above command is used for both Exchange 2007 and 2010.
Basic command structure for bulk import:
Get-Mailbox | Import-Mailbox –PSTFolderPath x: Full_Path_To_PST_Files
Note that the parameter x: Full_Path_To_PST_Files is the full path of the PST file.
The import order in turn:
Import-Mailbox –Identity 'Display_Name' - PSTFolderPath x: Full_Path_To_PST_File.PST
The –Identity parameter here can be the display name, email address or Exchange Alias, and the PST file name should be explicitly specified when executing the command.
Good luck!
