Unable to set flags, unknown error

[embersas]

I just updated to the latest N8N version (was 4 versions older) and latest IMAP node version (was 2 versions older).
Now I seem to have broken the ability to mark my email as seen?

Mail provider is ZOHO

Thanks for the report!

This issue is most likely related to your IMAP server. The error usually occurs when the server responds with an unexpected or invalid result during a flag-setting operation.

There haven't been any recent changes in the IMAP node related to setting flags, so it's unlikely this was caused by a node update. I also doubt that the N8N core update is responsible.

Did flag-setting work before the updates?
Please also try the node with a different mail provider (like Gmail) to check if the issue is specific to ZOHO.

Let me know what you find!

Thanks for the quick response!

Yes it has worked previously, noting that I only created this flow a few days ago (and only updated the versions today) so I don't have any long-term experience to comment on how stable it is with Zoho.

Is there any additional debugging / logging I can enable that might shed some more light?
