WAAS and IMAP

Hello

Sometimes the Outlook client displays succesful synchronization with the server but the OWA shows new mails that were not available with the client. The way to retrieve those mails is by means of Working offline flag on and then off. We are using WCCP and with IMAP out of WCCP, this does not happen. In fact, when it does happen, it is a random occurrence.

Have you people previously encountered this behavior? We have not yet debugged nor sniffed.

Thanks a lot!

Re: WAAS and IMAP

Hello

Have any of you seen WAEs drop the TCP connection between them and keeping the local TCP up? I’m not positive this is what’s going on but, couldn’t it be a possibility? The client sees the connection up but both WAEs have already dropped the connection for some reason. Alternatively, perhaps failure in database synchronization and because of that the local WAE understands there is nothing to retrieve from its remote peer.

Do you know a CLI command or a menu where I can look into it?

Does it make any sence?

Thanks

Re: WAAS and IMAP

In general, WAAS will maintain connection state end-to-end, so you shouldn't have a case where the connection is torn down between the WAAS devices,

but still established on the client/server.

Is this IMAP or HTTP traffic?

Thanks for your reply.

This is IMAP. OWA is used to tell whether e-mail has actually arrived. The Send/Receive button displays a successful synchronization but no new messages are shown.

Any suggestion would be greatly appreciated.

Re: WAAS and IMAP

Can we start by collecting information on how WAAS is handling the connections:

http://docwiki.cisco.com/wiki/Cisco_WAAS_Troubleshooting_Guide_for_Release_4.1.3_and_Later_--_Troubleshooting_Optimization

From there we can determine where to look next.

Thanks,
Zach
