Hello,
We have switch for Outlook for few weeks. And it worked immediately.
But as my colleague prefer eM Client, I kept looking for a solution.
The following screenshots shows our settings that are working well with the last version 10.
As you can see I use LOGIN instead of PLAIN. And as it works correctly, I did not go back to PLAIN in order to test if it is also OK.
--force-imap-auth LOGIN --force-smtp-auth LOGIN
These settings are working with 2 different PC, I guess it may help some other OVH customers using eM Client.
Sorry it is in french, but I think that it remains ‘understandable’ for most of the readers.
