Hi,
if i download a message and handle the attachments afterward i want to add a Tag like " Done + Timestamp" to the Subject. However the change will never saved.
Code:
```
mail.Subject = mail.Subject + " // DONE " + DateTime.Now;
```
Any Ideas why? Or isn´t it supported?

Hi Nico,
the only way to change the subject is to recreate the message. The code about should be working fine. Does the exception occur everytime you try to call AppendMessage? Are you sure the client is connected at that moment?
What you also can use to mark the messages are custom flags or, if using GMail, labels.
Greets,
