Pocket Outlook Email Filter

Question

 

Hi, I'm trying to develop an application closely combined with Pocket Outlook. I have a few questions regarding that. If any of them is already answered please point me to that. Here are my questions.

1. A filter should receive the emails before it reaches the Inbox. Extracts email details as-well-as all the attachments, targeted for a specific email ID. Block the required email to reach the Inbox.

2. Generate the default email-receive notification (Sound+Light+Vibrate combination depending upon the profile).

3. Create and put the email, along with attachment in the Outbox.

4. Get notified when an email is sent and moved to sent items folder.

5. Delete emails from Outbox, sent Items folder.

 

If (worst case) 1 and 2 above are not possible, is there any way to get events/callback when a new email reaches the Inbox and programmatically move it from the Inbox.

An additional question:

Is there any way to know, from the received email, the sequence in which the attachments were attached in the original email?

Thanks in advance.

Hi Kausikd,

 

You can use CEMAPI, which implement IMAPIAdviseSink that listens to any events occurred to a mail store. 

Click below link to get sample:

For delete and create a mail, you will open related email message stores , then do some operating:

Hi Thanks for the reply. As per your advice, I've downloaded the code from http://support.microsoft.com/default.aspx?scid=kb;en-us;230770 and able to run in XP. The application is nicely getting notifications.

BUT I need the application to run in WinCE. So after putting a terrific effort, I could decode the flow of the code and developed the wince replication. I am attaching my code here.

I've defined a simple Sync handler as described in http://msdn2.microsoft.com/en-us/library/ms531697.aspx and am waiting on a break point in OnNotify. My Application is not getting any event. I tried with:

1. Email is received

2. Email deleted.

3. Folder created.

4. Folder deleted.

As per MSDN the "Advice" methos id not implemented in WinCE for IMAPITable interface.

Can tell me where I'm wrong?
