Nokia E66 Zusätzliches Handbuch

To check your access point proxy settings, do the 
following:

Go to your device's access point settings (not Mail for 
Exchange settings).

Make a new access point based on the access point 
being used with Mail for Exchange.

Select 

 > 

. There should be 

two proxy settings. Delete the values in both settings 
and save the new access point.

Set Mail for Exchange to use the new access point.

If you cannot connect, you may need to contact your 
provider to get a more appropriate plan or see if there is 
another access point available under your current plan 
that does not use a proxy.

The Mail for Exchange setting 

 affects 

battery life and connectivity. The setting applies to 

 connections. A higher heartbeat interval improves 

battery life.

However, a heartbeat interval that is too high may lead to 
getting disconnected for a few minutes every hour. The 
ideal heartbeat interval depends on a variety of factors 
including Exchange server configuration, network 
conditions, and network configuration.

The heartbeat interval value that you set for your device is 
used as a starting point. Normally you can leave the 
default value as is. Mail for Exchange will monitor the 
connection and determine the best setting for your 
current environment. If you start with a value that is too 
high, you may notice disconnects until Mail for Exchange 
determines a proper heartbeat interval.

View the 

 setting to check your current 

heartbeat interval. If your determined heartbeat interval is 
consistently low (1-5 minutes), consider contacting your 
email account provider for different connection settings, 
removing the proxy from your access point, or notifying 
your system administrator.
