I’ve been busy the past few weeks. Work paid for a week long course to prepare me for the Microsoft 365 Identity and Services exam. I didn’t really like the instructor, but the labs and book have been helpful. We could tell from the syllabus that the instructor was not ready for a class as experienced as we were. He had the first hour set aside to help us get our lab environments up, but we had all already prepared before class started. He had another hour set aside to help us get our e-book, which we all downloaded before class started, so he had us stop for the day after lunch, so that he could prepare more material.
Work was fun today. One of our clients uses on-prem Lync 2013 server. AKA Skype for business. Their call center complained that when they tried to transfer calls direct to someone’s voicemail, the transfer failed. After a couple hours of pouring through logs, and making test calls I found that their voicemail had completely stopped accepting messages the morning before. So far, no one had noticed the extent of the issue. Exchange Unified Message requires a certificate which can’t be self signed to accept voicemails. It doesn’t require a internet CA certificate, so we were able to issue one from the DC and get voicemail working again. Learned a lot, and had fun fixing it. Was about to give up a couple times, but then I’d find another clue that got me closer.
