Cache related registry settings

For [HKLM\Software\Hewlett-Packard\Outlook PlugIn\Cache]:

•AttachmentsOnly=True: Indicates whether the Ofﬂine Cache Manager should cache only those archived messages that contain one or more attachments. The default is True. Changing this to False causes the Ofﬂine Cache Manager to cache all messages, whether or not attachment(s) exist. This is a user-conﬁgurable setting.

•EncryptCache=True: Encrypts ﬁles in the ofﬂine cache location using Microsoft’s Encrypting File System (EFS). The default is True. Depending on the computer’s security settings, only the current user can read ﬁles stored in the ofﬂine cache. Depending on the Folder options on the user’s computer, ﬁles may appear as green in Windows Explorer. This is a user-conﬁgurable setting.

NOTE:

Archived messages will only be stored encrypted in the ofﬂine cache if EFS is properly conﬁgured on the client. If you want to implement this option, consult Microsoft’s documentation for information on conﬁguring EFS.

•Location=: Folder in which the ofﬂine cache is located. Cached ﬁles are then stored in this location according to the current Outlook proﬁle. The administrator should not assign a value to this registry value in HKLM. It is initialized in HKCU to

\Documents and Settings\CurrentUser\Local Settings\Application Data\Hewlett-Packard\Cache upon ﬁrst execution for a user. This is a read-only setting.

•MaxDays=30: Maximum number of days archived messages are contained within the ofﬂine cache. This is based on the received date of the message, not the date it was archived or tombstoned. The Ofﬂine Cache Manager retrieves and caches any archived message where the received date is more recent than the number of days speciﬁed. Note that the MaxSize setting takes precedence over the MaxDays setting. Setting MaxDays to 0 causes all archived messages that can be contained by the MaxSize setting to be cached regardless of the received date. This is a user-conﬁgurable setting.

•MaxSize=100: Size, in megabytes, of the ofﬂine cache folder. If this size is exceeded, the cached .eml ﬁles are deleted in reverse chronological order until the size of the ofﬂine cache is once again below the limit speciﬁed by this setting. Note that this setting overrides the MaxDays setting. This is a user-conﬁgurable setting.

•ScanInterval=15: Number of minutes the Ofﬂine Cache Manager waits before instigating a scan for new archived messages. The timer for this setting does not begin until after all queued retrieval requests are complete. Therefore, if the Ofﬂine Cache Manager is busy retrieving archived messages this setting is inactive. This is a user-conﬁgurable setting.

•UseCache=True: Indicates whether the plug-in should use the Ofﬂine Cache Manager to cache messages that have been archived in the RISS. The default is True. Changing this to False prevents the Ofﬂine Cache Manager from starting and downloading archived messages, and messages are only cached per Outlook session. This is a user-conﬁgurable setting.

•CacheEML=False: Used in support of Outlook 2000 when UseCache=True. Setting CacheEML to True causes the plug-in to retain any .eml ﬁle downloaded and stored in the session cache location when Outlook is exited. This setting is useful in diagnosing retrieval issues. This is an administrator/diagnostic setting and should be modiﬁed only at the direction of HP technical support.

•CacheMsg=False: Deprecated and is no longer used.

•ConnectRetryInterval=5: Number of minutes the Ofﬂine Cache Manager waits before resuming the retrieval of archived messages after a dropped connection or other network failure occurs. This is an administrator/diagnostic setting and should be modiﬁed only at the direction of HP technical support.

•MaxConnectRetryCount=2: Number of times the Ofﬂine Cache Manager tries to recover from a network failure before exiting. This is an administrator/diagnostic setting and should be modiﬁed only at the direction of HP technical support.
