Hi,

I am facing the issue of compatibility between MS-Outlook 2010 and Zimbra server.Mail communication via webmail is fine.But when it comes to outlook i receive an email with changed subject and content.
e.g.
I am recepient in this
Sent mail:sender:xyz subj:hello
content:hello,have a nice day
Regards,
xyz

there are 2 possibilites at recevers end
1.recepient side:receiver:abc
Subj:hi
content:hiiee
Regards,
xyz
2.recepient side:receiver:abc
subj:hello
content:hello,have a nice day
Regards,
yyy
