Evolution: error when sending mail in HTML format
I have a fresh Arch Linux setup and am using Evolution for the first time, connecting to an Exchange 2007 server, using the "Exchange MAPI" profile.
Everything works great, except I can't send email in HTML format, even a very small "this is a test" email. The error message I get is
Could not send message: WriteStream: MAPI error MAPI_E_CALL_FAILED (0x80004008) occurred.
Any suggestions? I tried various debug logging per projects.gnome.org/evolution/bugs.shtml and did not find anything illuminating. In fact with LIBMAPI_DEBUG=15 I get a ton of stuff logged, including a bunch of MAPI_E_* return codes but I don't get the MAPI_E_CALL_FAILED code logged, dangnabit, and the log doesn't differ between a successful plain text test and the unsuccessful html test.
