I had this before. Try to reinstall your mailclient and check all permissions. I had this issue with mailenable pro / plesk

If you are using Horde as a webmail type, you can try reconfiguring it in the following way:
> cd %plesk_bin%
> defpackagemng --fix --type=webmail
> websrvmng --reconfigure-webmail
