Duplication of default folders
After certain period of using, some default folders, such as Deleted items,Junk email, etc., may
be duplicated in the Kerio WebMail’s folder tree.
This problem occurs under the following circumstances:
•besides Kerio WebMail, a user connects to his/her mailbox also via an email client which is
not directly supported by Kerio MailServer (e.g. MS Outlook Express),
•this unsupported email client is not in English,
•client applications connects to the server via IMAP.
If the conditions described above are met, the mail client might create its own set of special
folders (they cannot be found at the server since their names are in English there). These
changes are copied by Kerio WebMail.
In MS Outlook Express, the problem can be removed by renaming the critical folders (Sent Items
and Drafts) under Tools →Accounts:
1. Click on the particular email account and click Properties.
2. Select the bottom IMAP folder and change the Sent Items and Drafts folder names (for
details, see figure 1.18).

Messages signed in MS Outlook
Senderswho use MS Outlook with the Kerio Outlook Connector (however, thisproblem can arise
even if some obsolete email clients are used) can send digitally signed messages in a format
that is not supported by Kerio WebMail. This problem can be solved by allowing sending of
digitally-signed email messages in MS Outlook as clear text messages.
If your messages are digitally signed, in MS Outlook check the Send clear text signed mes-
sage when sending signed messages option under Tools / Options on the Security tab (see
figure 1.19). This option provides that also Kerio WebMail users may read the message.
