Dear all,

Recently we have decided to use Kerio mail server for some of our staff for their over the air sync.

In the POP3 Download function, we have ticked the box "Drop duplicate message" which means POP3 download function will leave a message copy on the REMOTE server, the problem we are facing now is that, everytimes POP3 download the msg remote server, it's not only download the new msg but also the old msg which have download by the previous session. we have enabled the schedule with every 1 minute, the POP3 function will start to download and our user is good flooded with the old messages from the previous session, instead of new mail only.

Anyone have an ideal how to fix this ?

Many thanks

Unless Kerio made a change recently to the POP3 functionality, the POP download should remove everything from the original mail server.

If you select "Drop duplicate messages" in the POP3 Account settings, then mails to multiple users on the server will only be delivered to one recipient. Alternatively, if you do not select "Drop duplicate messages" then all recipients will receive a copy for each recipient specified. iewarticle&kbarticleid=68

Have you manually edited your config file, to not remove messages when downloading via POP3?

I'm bumping this thread because I have the same problem. When I click "Download Now" for any of my accounts, it removes the copy from outside client. It stays on Kerio and iPhone, but not on my other webmail setups. Why is that?

With the upcoming version 7.1 (still in Beta) you can tick the box

"Leave messages on server"

for the POP3 download. This is not possible with previous versions.
