When the Sharing feature is enabled, users can share any of their folders, including their mail folders, calendars, address books, task lists, Document notebooks and Briefcase folders.
Users specify the type of access permissions to give the grantee. They can share with internal users who can be given complete manager access to the folder, external guests that must use a password to view the folder content, and the public access so that anyone who has the URL can view the content of the folder.
When internal users share a mail folder, a copy of the shared folder is put in the grantee’s folder list on the Overview pane. Users can manage their shared folders from their ZWC Preferences Sharing folder. In this folder users see a list of folders that have been shared with them and folders that they have shared with others.
When distribution lists are used to manage shared items, members of the distribution list are automatically granted rights to the shared item. Administrators manage the shares from the DL’s Shares tab. All members of the list have the same share privileges that the grantee defined for the shared folder. When a member is removed from the distribution list, the share privileges associated with the DL are revoked.
Users must notify the administrator that they have shared a folder with the distribution list. When the administrator is notified, the administrator publishes the shared item in the Shares tab to make the shared item available to members of the DL. When a new shared folder is published, existing members of the DL are automatically notified of the new shared item.
New members added to the distribution list can be automatically notified about items that are shared with them. They can accept the shared item from their ZWC Preferences>Sharing tab.
Preferences is enabled by default. Users can modify the default preferences that are configured for their account. You can disable preferences and the Preferences tab does not display in users’ mailboxes. They cannot change the default configuration for features that are set up for their accounts.
Account quota is the amount of space in megabytes that an account can use. The quota includes email messages, Calendar meeting information, task lists, Documents pages and files in Briefcase. When the quota is reached, all email messages are rejected and users cannot add files to their account. If you set the quota to 0, accounts do not have a quota. See
Account Quota and the MTA
Users can be notified that their mailboxes are nearing their quota. The percentage threshold for quota notification can be configured. When this threshold is reached, a quota warning message is sent to the user. The quota percentage can be set and the warning message text can be modified in the Advanced tab settings for COS and Accounts.
The Address Book size limit field sets the maximum number of contacts a user can have across all of their address books. When the number is reached, users cannot add new contacts.
You can specify a policy that sets the maximum number of failed login attempts before the account is locked out for the specified lockout time. This type of policy is used to prevent password attacks.

When this box is checked, the “failed login lockout” feature is enabled and you can configure the following settings.
|
|
Number of consecutive failed logins allowed
|
The number of failed login attempts before the account is locked out. The default is 10 attempts. If this is set to 0, an unlimited number of failed log in attempts is allowed. This means the account is never locked out.
|
|
|
|
The amount of time in seconds, minutes, hours, or days the account is locked out. If this is set to 0, the account is locked out until the correct password is entered, or the administrator manually changes the account status and creates a new password. The default is 1 hour.
|
|
Time window in which the failed logins must occur within to lock the account
|
The duration of time in seconds, minutes, hours, or days after which the number of consecutive failed login attempts is cleared from the log. The default is 0, the user can continue attempts to authenticate, no matter how many consecutive failed login attempts have occurred.

|
Session idle lifetime sets how long a user session remains active, if no activity occurs. Activity includes any clickable mouse action, such as viewing contents of a folder or clicking a button. The default is 2 days.
|
|
You can manually expire a user’s web client session from the administration console Expire Sessions link.This forces the current session of the account to expire immediately.
|
The email retention policy for email, trashed and spam messages is set by COS. When the message purge function runs is set by the message purge command.
|
|
|
|
|
|
Number of days a message can remain in any folder before it is automatically purged. The default is 0; email messages are not deleted. The minimum configuration for email message lifetime is 30 days.
|

The server manages the message purge schedule. You configure the duration of time that the server should “rest” between purging mailboxes from the administration console, Global settings or Server settings, General tabs. By default, message purge is scheduled to run every 1 minute.
For example, when the purge interval is set to 1 minute, after mailbox1 is purged of messages that meet the message lifetime setting, the server waits 1 minute before beginning to purge mailbox2.
Attachment viewing rules can be set from Global Settings, by COS, and Accounts. The global setting rule takes precedence over COS and account settings. You can select from four options.
The appearance of the Zimbra Web Client user interface can be changed. A number of Zimbra themes are included with ZCS, and you can create others. You can select a theme to be the default and the themes that users can select from to customize their user experience.

The Preferences Import/Export tab lets users export all of their account data, including mail, contacts, calendar, tasks, Documents notebooks and Briefcase folders. They can export specific items in their account and save the data to their computer or other location. The account data is saved as a tar-gzipped (tgz) archive file so that it can be easily imported to restore their account. Individual contacts are saved as .csv files, and individual calendar files are saved as .ics files. The data are not removed from their accounts. The exported account data file can be viewed with an archive program such as WinRAR archiver. Any of these files can be imported into their account from the same tab.
