Mail For Exchange (MfE)

For general informatipon on synchronising your N900 with a mail or calendar server, please see the sync page

This page answers questions which are commonly asked by new N900 MfE users. It is mostly based on the analysis of the MfE support thread.

The current version of the page addresses two versions of MfE:

  • Sales release ()
  • PR1.1 ()


Compatibility

What server versions are supported by N900 MfE client?

Microsoft Exchange 2007 with service packs on top. MS Exchange 2010 also works fine according to users reports.

What server versions are NOT supported by N900 MfE client?

  • Microsoft Exchange 2003 (is supported in the first MfE update which is not available for public yet).
  • All non-MS services, although there has been reported success synchronising with Google services.

How can I check is my server version supported or not?

  1. Take the logs following the steps described in the section How can I turn the logging ON or OFF?
  2. Grep (search) for "MS-ASProtocolVersions:" in the logs. If it contains "12.1" token, there is no problem with the version of your sever (if it is Microsoft Exchange server, not something else).

Why is feature XXX present in MfE for S60 but not for the N900?

S60 and Maemo MfE are different implementations.

The table below tries to summarize the most important differences between S60 and Maemo MfE implementations.

Feature S60 status Maemo status
E-Mail YES, subfolders are not synced YES, subfolders are synced
Calendar YES YES
Tasks YES YES
Meeting invitations replying YES NO
Corporate address book (GAL) YES NO (*)
Exchange servers support 2003, 2007 2007 (*)
Autodiscover YES YES
Provisioning support Partly YES NO

(*) This feature will be supported in a forthcoming MfE update

Lack of provisioning support in MfE for the N900 is the most common cause of problems with corporate Exchange servers in North America. See Provisioning for additional details.

Known issues

Provisioning

N900 is considered to be "non provisioning device" from Exchange server point of view. It basically means that it can not be managed from Exchange server - administrator can not wipe your device, request you to use autolock and so on. Basically, all the provisioning data received from the server is ignored and the server is informed that N900 MfE does not support this feature.

Exchange administrator can configure the server in 2 ways - he/she can allow to use non-provisioning devices or disallow. In the second case N900 MfE will not work as server will reject the connection.

Post with Exchange server 2003 management console

SSL-related errors

The error message is displayed "Exchange server requires secure connection or account is disabled".

This infamous error message is caused by the fact that server certificate is untrusted from Maemo MfE client PoV.

Possible root causes and workarounds:

Server certificate is either self-signed or signed by the non-trusted authority (root certificate is not visible in N900 "Certificates" application).

In this case, the server certificate shall be added to N900 certificate storage. Check this message and the thread after it for additional details.

Keep in mind - self-signed certificate shall have "CA" field. Otherwise, N900 certificate manager will not allow to install it.

Another important hint about importing certificates.

Unfortunately, there is no way to disable certificates check at the client side in the current MfE release.

Server certificate is valid and trusted but MfE fails to sync

Check this bug.

Troubleshooting

How can I check the version of the software installed in my N900?

  • Open "Settings" view
  • Scroll to the "General" section
  • Open "About product" applet
  • Check the "Version" string

Versions strings versus releases:

How can I turn the logging ON or OFF?

In order to turn the logs ON:

  1. Install syslog and reboot the device
  2. open terminal
  3. Execute the command: sudo gainroot
  4. Execute the command: cat /dev/null > /var/log/syslog
  5. Execute the following commands:
    1. gconftool-2 -s --type=int /apps/activesync/AsDaemon/Syslog/MinLogLevel 0
    2. gconftool-2 -s --type=int /apps/activesync/modest/Syslog/MinLogLevel 0
    3. gconftool-2 -s --type=int /apps/activesync/AsProvider/Syslog/MinLogLevel 0
    4. gconftool-2 -s --type=int /apps/activesync/AsBackup/Syslog/MinLogLevel 0
    5. gconftool-2 -s --type=int /apps/activesync/asapplet/Syslog/MinLogLevel 0
    6. gconftool-2 -s --type=int /apps/activesync/AsStatusApplet/Syslog/MinLogLevel 0
  6. Reboot the device
  7. Initiate the synchronization session

/var/log/syslog will contain the logs. In order to filter only activesync-specific logs the following command can be used: 

     grep activesync /var/log/syslog

In order to turn the logs OFF, execute the following commands from xterm: 

    gconftool-2 -u /apps/activesync/AsDaemon/Syslog/MinLogLevel
    gconftool-2 -u /apps/activesync/modest/Syslog/MinLogLevel
    gconftool-2 -u /apps/activesync/AsProvider/Syslog/MinLogLevel
    gconftool-2 -u /apps/activesync/AsBackup/Syslog/MinLogLevel
    gconftool-2 -u /apps/activesync/asapplet/Syslog/MinLogLevel
    gconftool-2 -u /apps/activesync/AsStatusApplet/Syslog/MinLogLevel

After device reboot the logs will not be collected.
