hi, first of all sorry for my english
30 PC's and a local server mail Hmailserver
every PC have just one account with IMAP protocol.
everything works perfectly in 2010 with thousands of emails a day , received and sent.
after update outlook 2007-->2013 start problems begin duplicating email . each synchronization creating hundreds of duplicate.
I try uninstall and install office after remove it with the MS fix.
I try format a pc, clean install windows 7, clean install office 2013 but the problems persists.
in the computer with the problem I changed email program I have no problem , only with Outlook 2013
thunderbird works, en-client works, eudora works, windows live mail works, webmail (round cube) works outlook 2007 works.
All with the same configuration.
I tried contacting the telephone support microsoft and the aid was non-existent .
It 's funny how the only program fee is the one that does not work
bye
Fabio
