Been using the free version of eM for several months. Now, out of the blue, when I launch eM I get a dialogue saying “Password required for CalDAV” with places to enter the user name and password. Those fields are filled in with the correct info. Even if I re-type in the correct info and press “OK” the error box closes, the OPERATIONS window opens for a split second and then it closes and the error box re-opens. All the credentials are entered correctly. Nothing has changed with my mac.com account. I haven’t changed anything in eM. It’s just stopped working. Ideas? Solutions?
Follow up - tried deleting and re-creating the CalDAV account. Same problem persists.
Hello,Is it possible that you enabled two-factor authentication on your iCloud account? If so, you will need to generate an app-specific password for eM Client. If not, can you check your antivirus/firewall and add an exception for eM Client?
