Case #08115189 Feature Request: Option to Send Backup Report as Plain Text in Email Body Instead of HTML Attachment

[sven.madai@switch.ch]

Hi R&D Forums

As a service provider, we send automated job notifications to our customers. These notifications currently include the detailed backup report as an HTML attachment.

Over the past few weeks, we have observed that these notification emails are increasingly being quarantined by customers using Microsoft Exchange Online. Analysis of the mail headers confirms that SPF, DKIM, and DMARC are all correctly configured and pass validation. However, the HTML attachment is being flagged as suspicious by Microsoft Exchange Online Protection (EOP), resulting in quarantine – even when the sender address has been whitelisted tenant-wide and a Mail Flow Rule (Transport Rule) has been configured on the recipient side.

Have you received similar error messages from other customers or service providers?
How has your experience been over the past few weeks?

Feature Request:
We would like to request that a future version includes the option to send the detailed backup report as plain text directly in the email body, as an alternative to the current HTML attachment. This would significantly improve compatibility with strict spam and malware filtering policies such as Microsoft EOP.

Environment:
- Product: VBM 365 8.4.x
- Sender: Exchange Server on-premises (SE CU1)
- Recipient: Microsoft Exchange Online (EOP)
- Issue observed since: approximately May 2026

Thank you very much for all your feedback—we have already reported this to Veeam Support and logged it as a feature request.

Hi STS,

I apologize for the late reply.

It seems that no other service provider here in the forums has reported the same issue. I also haven’t heard of other VSPC having issues with emails blocked by Exchange Online Protection.
Regarding the feature request, I can make a note of it, but I don’t expect such a feature to be implemented in the foreseeable future.

May I ask if you have upgraded to v8.5 in the meantime? Are the emails still being blocked by Microsoft?

Best,
Fabian
