Since upgrading from 3.8.5-2+b3 to 3.12.1-1 evolution is unable to retrieve approximately 10% of the mails in my imapx inbox on exchange. I've reported this upstream but also filing here since I think this should be given consideration as to whether it make the package unsuitable for testing. Details, including logs are in the upstream bugzilla #729172. Thanks, Ian.
Upstream have recommended trying 3.12.3 which improves on these issues. Is there any timeline for that update? Evolution in Jessie is almost unusable for me due to constant crashes and stalls. Ian.
