So, once again, we had another "fresh install" that bombed when you try to connect.
Fortunately, this time I was working with a PC/Network guy that knew his stuff.
I am attaching the OpenSSL .dll files that we used for this fix. They are version 1-1, so they are exactly what is needed.
After you have downloaded and extracted them, place these .dll's in the Folders:
C:\Program Files\Mitel\MiVoiceOffice250
and in any folder of a system version that you can't connect with, such as:
C:\Program Files\Mitel\MiVoiceOffice250\6.3.11.109
C:\Program Files\Mitel\MiVoiceOffice250\6.3.9.106
etc.
I will be curious if this fixes it for others as well!!!!
