sendobject works only one time

[absolutegrinding]

DoCmd.SendObject acSendReport, "INVOICE", acFormatPDF, holdemailaddr, , , "Current Invoice from xx", "Invoice Attached", False
Have been issuing this statement for several years, and now, I receive "[accessfile] can't send this email"


Have also used
DoCmd.SendObject acSendReport, "INVOICE", acFormatPDF, holdemailaddr, , , "Current Invoice from xx", "Invoice Attached", True
but same result.
If I close and open the access file, it will send one email, then I receive the same message.
Checked for new updates to access.
Any suggestions?

A client had this start happening, it slowly spread through the company. I suspect a Windows or Office update caused it. I switched them to Outlook automation, which worked.
