Dear Lirex Lirex,

Good day! Thank you for posting to Microsoft Community.

Based on the issue you have shared, the issue with importing PST file in Microsoft purview seems there is a service degradation posted in Microsoft service health dashboard with the tracking number MP1011050. You can refer to the incident detail below:

Title: Some admins receive a 500 error when attempting to generate Shared Access Signature (SAS) URLs during PST imports

User impact: Admins receive a 500 error when attempting to generate SAS URLs during Personal Storage Table (PST) imports.

More info: Admins receive the following error message: "The remote server returned an error: (500) Internal Server Error."

Current status: We've further identified that a security code update inadvertently introduced a regression that's causing a permissions issue with a section of storage infrastructure, resulting in a 500 error when users attempt to generate SAS URLs during PST imports. We're developing and testing a fix to repair the permissions issue, and once the fix has been validated, we'll start a deployment to affected users.

Scope of impact: Your organization is affected by this event, and some admins can't generate SAS URLs during PST imports.

Root cause: A security code update inadvertently introduced a regression that's causing a permissions issue with a section of storage infrastructure, resulting in a 500 error when users attempt to generate SAS URLs during PST imports.

For affected customers to easily identify the information here, you may subscribe to this thread for updated information. I will post back here once the issue is resolved. Thanks in advance for your understanding! Your patience and cooperation will be highly appreciated.

Thank you for your patience and understanding. We apologize for any disruption this service degradation may cause to your operations.

Have a good day!

Hi,

the support of my country distributor made me add the user account nominatively in the roles mandatory to do mail import/export, even if the user was a global admin and the global admin group has already the right roles, I was sceptical but it worked.

I don't know if they've done anything else from their side (I think not), but at least give it a try and give us a feedback.

Hello,

Same issue with all my customers tenants in France.

I'm working on many migration from Exchange On Prem to 365 Online and all is blocked.

It's an aleatory issue but recurring since 2019.

We need a real solution !
