Turns out its my Mitel software on my Lenovo X1 Yoga running Win10. I've uninstalled and re-installed twice but have same issue. Settings in Mitel SysAdmDiag don't save right. I can edit existing connections but settings don't keep and also when I create new connections, it saves them but can't use them. Error states it can not find entry.
I whipped out my last ThinkPad (Win7 Ult, actively using on Mitels about 14mos ago) and it programmed the system up just fine.
Very frustrating. Does anyone know of any known issues with Win10 Pro and Mitel software?
Big Thanks for any feedback!
