Account keeps restoring back to a certain user

[Dee]

Hi everyone

My manager has found it annoying that everytime he needs to send an email he
has to manually swith his correct mail account by cliking Account at the top.
Once the email is sent, the mail account reverts to original. If you know
how to prevent this reverting of an mail account, please let me know.

The Default mail account is the one used for a new msg, change the default.
A reply is sent using the account it was received on
