We have jobs to import PST files (attach screenshot) using office 365 admin portal, i want to get job's status using Microsoft graph API it is possible?
Non of the exchange online administration functionality is available in Microsoft Graph API at this time.
There are Exchange Online PowerShell commandlets that are available. have you checked there? https://learn.microsoft.com/en-us/powershell/exchange/exchange-online/connect-to-exchange-online-powershell/connect-to-exchange-online-powershell?view=exchange-ps
That team is starting to plan for this, with the intention then of being part of our Microsoft Graph PowerShell SDK too.
