2018-02-19 Mac Mail & High Sierra

More than one user - and my self inclusive - have experienced problems with Mac Mail on the latest version of OS from Apple - currently 10.13.3

I see lot of different issues, and therefore CANNOT recommend this application for email.

User Microsoft Outlook for Mac for your DTU email-account - this will at least give you something that works.

IF you have other email-account you could go for third party solutions: one dtu-user mentions Spark. I however have not knowledge of that product.

Should there be a solution I will let you know !
