The Compound Document File contained a Stream with an invalid FAT chain

Hi,

While sending excel sheets to some clients through email (its not happening to every one), the email gets delivered however the attachement gets deleted. Their network team sent us following reason.

We have checked the gateway and the reason is the attached Excel file , it has the following in the logs of the gateway " The Compound Document File contained a Stream with an invalid FAT chain. "

We are using CDO.Interop for sending emails.

Any suggestions, why this is happening?

Regards, Vinay

Hi,

We are not sure if the issue is related to Aspose.Cells(older
version that you might be using).

But could you try our latest version/fix v4.9.1.x, I have
attached the version here. Let us know if it works fine now or your clients still finds this issue.

Thank you.

Yes, we are using the one of the latest versions; its 4.9.0.5.

Hi,

Could you share us the invalid generated file and the template file here? We will check your issue soon.

Thank you.

I’ve send you the attachment in a private post ID: 238440
