Maybe you have seen it an e-mail with a winmail.dat file as attachment. This is caused by a sender which sends an e-mail in RTF format to a user that has an e-mail client which does not support RTF.

In Exhange you can have this issue also when forwarding mails to a mailcontact, this can be solved in two ways:

  • per mailcontact
  • per remote domain

First per mailcontact, for this you will need to get the properties of the mailcontact. You will then see the general tab, this contains the information below:

With the option use MAPI rich text format you can specify if this needs to be applied always, never or that the default value needs to be used.

The other way is by defining this per remote domain, this can be configured by selecting the Hub Transport Server and open the remote domains tab. Here you can specify a seperate domain for which you want to specify the settings. When you already have configured a remote domain for which you want to change this just get the properties of it. Then go to the tab Format of original message sent as attachment to journal report.

Here you will find the following information:

Below the Exchange rich-text format you can define if this will be used always or never. Besides this you can define that this setting is specified per individual user
