Hi.,

Have created MS word doc using Visual force (similar to standard Mail merge functionality).

Main Key is here,

<apex:page standardController="Order__c" recordSetVar="Order" showHeader="false" contentType="application/msword" extensions="Date_Update_ACL" action="{!update_date}">

The reason to move to custom functionality instead of using mail merge in Activity History, we need to generate mail merge doc for more than one record, upon generating the doc we need to update some fields in that record.

Here the problem is, our visual force page generate the MS Word doc in Fire Fox browser but not working in internet explorer.

I dont understand the reason, have you faced this kind of issue, any workaround for this? 

Any help appreciated.

Note: PDF can be generated easily but we need to generate in MS word
