I use 1.6.2 and it is working as expected for me. Can you please provide steps on how you installed this onto thunderbird?
The steps I followed to get this working was by going into(on thunderbird) Tools > Add-Ons > search opacus and then selecting ‘Opacus SugarCRM Thunderbird Extension Standard’
After putting in the correct information it worked as expected.
I suggest trying to contact Opacus to get extra support about this, but hopefully other community member may be able to assist further. Just to confirm have you added all the correct information in the Add ons > Prefrences(Opacus) .
Ensuring you have the SugarCRM URL set to something like http://mycrm.crm.com or http://mycrm.com/crm and not something like: http://mycrm.com/crm/index.php?action=Login&module=Users
I tested my idea out, and using Ubuntu 14.04 allows me to use Opacus 1.6.2
That being said, I played with my 16.04 version of Ubuntu.
Has anyone successfully made it work with Ubuntu 16.04?
I installed one of the other versions (professional) and when I enter the server log in info, it tests fine. I tried “test settings” function on 16,04, and it does not work on the test settings.
Thanks for other experiences between v14.04 and v16.04.
