OWA Plain text
So I've noticed this "problem" on our internal Exchange system and at every customer site that I deal with that has Exchange 2007: when you send e-mail to an external recipient via OWA, it is sent as plain text. This is sometimes very annoying but I could never find a solution or even anyone asking the question. After some (more) hunting the other day I actually came up with a possible solution: http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=2012151&SiteID=17. I had our internal IT folks implement the fix and it's now working. It's a quick command to run in Powershell and completely reversible:
set-remotedomain -Identity Default -ContentType MimeHtmlText
You can verify the setting on an Exchange 2007 server by running the following:
Get-RemoteDomain -Identity Default
The documentation for set-remotedomain indicates that the default setting for the ContentType option is MimeHtmlText; however, this is not (based on my experience with multiple production Exchange installations) the default Exchange setting.
