Unable to delete emails via Webmail

[Dimitris]

When trying to delete all emails from Roundcube after search, and select > *All > Dellete i get the following error:
Server error: UID MOVE: error in IMAP command UID MOVE : too long argument (0.001 + 0.001 secs)

How to overcome this issue? the emails is around 69k.

Thank you,
