Sounds like a dovecot setting to me.
Vivek, are you seeing any error messages in the dovecot.log file?
Try adding this to your dovecot local.conf file (just to see if it makes
any difference for you):
protocol imap {
imap_client_workarounds = "delay-newmail"
# Maximum number of IMAP connections allowed for a user from each IP
address.
# NOTE: The username is compared case-sensitively.
mail_max_userip_connections = 20
}

Vivek,
Does this have anything to do with dovecot, and have you checked that it
is not some issue with the mail client/client OS. I believe that Windoze
OS's have this setting...somewhere. You may check that.

Hi All,
Please see the following point by point information of my mail server.
1. Operating system: CentOS release 5.8 (Final)
2. IMAP users: 120 - 150
3. mail_max_userip_connections: no such line found in my
/etc/dovecot/local.conf
4. Yes, I always restart my dovecot, after restart it, all outlook
work for 10 min. After 10 min it start the disconnection again.
When outlook goes offline, I clicked on send and received then it
gives error to sync subscribed folders.
5. I used ping test to my server for 1000 of packets I found no
packet drop.

Did you miss this post?:
How many imap users do you have?
Have you added a value for mail_max_userip_connections in your
/etc/dovecot/local.conf file? What value do you have?
Did you restart dovecot after changing dovecot settings? (qmailctl
doesn't do anything with dovecot)
