Hi

Thank you for the information!

We're also experiencing a lot of problems with messages not deleting, and we've been working with technical support and the sales manager on this issue.

We can try several workarounds, but we believe this is more likely a product improvement by Intersystems. They're working on it in 2026 Iris version.

Finally I edited this class and it works

Thanks :)

I did, but it says "/// Do not edit this file - use external tool to generate it."
