# Set the shared mailbox name and the path to the PST file
$sharedMailbox = "shared-mailbox@example.com"
$pstFilePath = "C:\Path\to\your\PST\file.pst"

# Create a new mailbox import request
New-MailboxImportRequest -Mailbox $sharedMailbox -FilePath $pstFilePath -TargetRootFolder "Inbox" -Name "PST Import" -BadItemLimit 10

# Monitor the progress of the import request
Get-MailboxImportRequest | where {$_.Name -eq "PST Import"} | Get-MailboxImportRequestStatistics

# Wait for the import request to complete
while ((Get-MailboxImportRequest -Mailbox $sharedMailbox -IncludeReport).Status -like "Queued" -or (Get-MailboxImportRequest -Mailbox $sharedMailbox -IncludeReport).Status -like "InProgress") {
Write-Host "Waiting for import to complete..."
