Replied emails comes as Unread in Lotus Notes

Hi all,

I have a user with me who faces an issue with her emails that when ever she replies to emails from Lotus Notes, those replied emails turns to “Unread”. This happens within a two minutes time after she has given a reply to the mail.

We tried replacing the design of her server copy in LN,but still no luck.

Is there any solution for it?

Thanks,

Vidhya
