Microsoft Exchange Client Extension v/s COM Add-in

[Rahul]

Hi,

I am new to this field so Please help me out how to start..

I have read Microsoft Exchange client extension and Com add-in both.
But I am unable to find out the difference between these two i.e which
one should be used in which situations?

I have to do following tasks:
a> Finding details of mail while sending?
b> Finding details of mail while receiving?
c> If mail is stored in "Message Storage" then how to get message-body
from it?

Please help me which will be the best way to solve this.

Thanks in advance.

Regards
Rahul.

As per my understanding Microsoft Exchange client extension is not
related to any mailer i.e. it will work will all mailers like
outlook,outlook express and opera M2.
But COM add-in will be specific to outlook.

Is my understanding correct?

Your understanding is not correct. An Exchange extension will only run in
Outlook. You would need completely different, totally incompatible software
to work with OE or opera.

Exchange extensions are not supported going forward with Outlook and can
only be written using Extended MAPI (C++ or Delphi only, unmanaged code
only). Extended MAPI has a large learning curve.

COM addins can be written in any managed or unmanaged code language that
supports work with COM and can perform Outlook automation and can handle the
extensibility interface events.

A COM addin is suitable for what you want to do. However, again, you would
need completely different incompatible code to work with OE or opera.

Ken,

Where have you read the Exchange Client Extensions are not supported in
Outlook ?
Are you saying in the next version of Outlook, 2008 ?

Michael, "going forward" was what I said. The plans are to not support ECE's
in Outlook 14. So writing a new ECE at this point will limit the code to
Outlook 2007 and earlier. Sorry for the confusion.
