Support for Exchange ActiveSync policies and remote wipe
For IT administrators
If a user sets up an Exchange ActiveSync (EAS) account on
a HP webOS device, the device enforces only the EAS IT policies
listed here. If the company uses IT policies other than the ones
listed here, the IT administrator cannot enforce these other policies
on the device. The user, however, is still able to set up an EAS
account.
Setting password policies
IT administrators can force employees using a webOS device
to secure the device using IT password policies, including the following
options:
-
Password complexity (numeric or alphanumeric): Password
strength plays an important role in securing a device. A webOS device
supports a combination of numeric and nonnumeric characters.
Note If the IT administrator enforces an alphanumeric password,
the webOS device requires that the password include a minimum of
one non-numeric character.
-
Minimum password length (2–18): On a webOS device,
alphanumeric passwords can be between two and 18 characters. Numeric
passwords must always be four characters or more.
-
Maximum number of failed password attempts before local
wipe: IT administrators can set the number of failed password
attempts allowed to the user on the device before a local wipe occurs.
-
Autolock after X minutes of inactivity: IT administrators can
set the maximum password timeout interval in the Exchange policy.
-
Remote wipe: IT administrators can delete all
data from a user's device by doing a remote wipe from the Exchange
management console. Use remote wipe in case a device is stolen or
as a way to clear data from a device before it is transferred from one
employee to another.
Note An IT administrator can also perform a Full Erase directly
on the device to erase all data without using the remote wipe policy.
Setting up EAS policies on multiple EAS accounts
The IT administrator can enforce the EAS IT policies on all
EAS accounts on a device. Even if a user creates a personal EAS
account with an external vendor who hosts the email account on an
Exchange server, password policies enforced by the IT administrator may
apply to the personal EAS account.
-
If the first account the user creates has policies
associated with it, those policies are enforced for that account.
The user sees a series of screens prompting the user to enter the
numeric or alphanumeric password, depending on the policy settings:
-
The user can create additional EAS accounts with or without
EAS policy requirements. If the account requires EAS policies, the
user is asked for them during setup (as shown with the first account).
-
The most stringent settings from multiple EAS policies are
enforced on all EAS accounts. For example, if a user has two EAS
accounts with different timeout policies (one with a 5-minute timeout
period; the other with a 10-minute timeout period), and different
password policies (one requiring a 5-digit password; the other a
10-digit password), the device will enforce a 5-minute timeout period
and a 10-digit password requirement on both EAS accounts.
-
If the IT Administrator enforces policies on an account after
the user has created and synchronized the account, the supported
policies are applied to the account on the device, unless the device
already has an EAS account with policies that are being enforced.
-
If the IT administrator enforces policies on an already-created
account, policy changes to other EAS accounts are not enforced,
and those accounts stop synchronizing.
-
If the user removes the EAS account whose policies are being
enforced from the device, the user can create a new EAS account,
and the IT administrator can enforce policies in this new account.
The password for the deleted account remains the active password
unless the user changes it by entering a new password when creating
the new EAS account on the device, or by using the Secure Unlock
feature in the Screen & Lock application on the device.
For end users
If you set up an Exchange ActiveSync (EAS) account on your
device, the device supports the remote wipe feature and any password
policies enforced by your IT administrator.
Remote wipe
Remote wipe clears all data from your device. Use remote wipe
if your device is stolen, or as a way to transfer a device to another
employee. The IT administrator can perform the remote wipe, or,
on Exchange Server 2007 only, you can perform a remote wipe by logging
in to the Exchange server via OWA.
Password policies
Find out from your IT administrator what you need to do to
follow the policies that are enforced in your EAS account. You must
follow the password policies your company requires.
-
Password complexity (numeric or alphanumeric): Password
strength plays an important role in securing a device. Your device
supports a combination of numeric and non-numeric characters.
-
Minimum password length (2–18): On your device,
alphanumeric passwords can be between two and 18 characters. Numeric

-
Maximum number of failed password attempts before local
wipe: IT administrators can determine the number of failed
password attempts allowed to you on the device before a local wipe
occurs.
-
Auto-lock after X minutes of inactivity: IT administrators can
set the timeout setting for your EAS account.
Setting up EAS policies on multiple EAS accounts
If you create multiple EAS accounts on your device, the IT
administrator can enforce the EAS IT policies listed above on all
of your EAS accounts.
-
If the first account you create has policies associated
with it, those policies are enforced for that account. You see a
series of screens prompting you to enter the numeric or alphanumeric
password, depending on the policy settings:
-
You can create additional EAS accounts with or without EAS
policy requirements. If the account requires EAS policies, you are
asked for them during setup (as shown with the first account).
-
If the IT Administrator enforces policies on an account after
you have created and synchronized the account, the supported policies
are applied to the account on the device, unless the device already
has an EAS account with policies that are being enforced.
-
The password for deleted EAS accounts remains the active password
unless you change it by either entering a new password when creating
the new EAS account on your device, or by using the Secure Unlock
feature in the Screen & Lock application on the device.
