Hi,
this is the error that shows up:

A network service error has occurred. msg: system failure: deleting contents for folder 3
code: service.FAILURE
method: FolderActionRequest
detail: soap:Receiver
trace: btpool0-6:1221719167467:023ef868888a21ae

How can I solve this? I'm using Zimbra desktop 0.90 build 1278 against a Zimbra server as stated in my profile.

Thanks,
Luca.
