I have 2 users who is experiencing slow connection speeds to our exchange 2010 server using MAPI on Windows Live mail. The access the mail remotely and have a good internet connection. They received the following error intermittently: 'Your IMAP server has not responded in 300 seconds. Would you like to wait another 300 seconds for the server to respond?' but complain the the service is poor most of the time.
They used to POP and plan to move to Outlook Anywhere in a couple of months and as a interim measure we moved them to MAPI on Win Mail.
1. Is MAPI know to be slower than Outlook Anywhere?
2. Are there any setting in Exchange that could speed things up?
3. Are there any client side setting that could speed things up?
3. Is there any advantages to move all client that currently use POP or MAPI over to OWA or OA?
