I have two different email accounts coming to my 8703e using BIS. When I compose an email, the device is sending from one of my addresses, I want it to use the other one.

I did a search and found that I can go to Options > Advanced Options > Message Services and change to my preferred email in the Messaging (CMIME): field, but only one of my email addresses is showing up there (not the one I want to use as my default, conveniently).

Have I got something set up wrong? I can confirm that I am receiving email from both accounts on my device, but I am only able to compose from one of them.

Thanks in advance.

You're missing a service book for the other account, it sounds like.

Then, go back to your default messages and set it.

Thanks for the quick reply and good advice.

, you are very welcome.
