[horde] Activesync calendar won't sync, log shows Duplicate entry

[John H. Bennett III]

Hello all,

I'm seeing this error in my log.

Feb 15 12:47:27 jbesmith HORDE: SQL QUERY FAILED: Duplicate entry

I read this link, http://wiki.horde.org/ActiveSync/KnownIssues#toc9,  
but until I remove this entry, my calendar won't sync with new/changed  
entries, everything else seems fine.

Is there anything I can do, short of completely deleting the account  
and recreating it?

Thank you,

John Bennett
