I purchased MS Office Pro Plus 2024 with a lifetime use license through License Tom, an official Microsoft reseller. The software was just what I paid for (even if I think it's crazy that MS is getting rid of Publisher, but that's neither here nor there). I received my instructions to download, install, and activate the software immediately, and they worked perfectly. The initial email warned me that Microsoft might prompt me to reactivate after 30 days, despite it being a lifetime license. That's exactly what happened, and my activation code no longer worked automatically. I sent an email to David with License Tom, with screenshots of my error message. I received a reply almost immediately talking me through how to use the alternate activation process by phone (and text, and web link, but it starts with a phone call), which I was able to easily follow and it worked exactly as it was supposed to. I followed up with a quick thank you, to which I received *another* almost immediate reply. So to put it mildly, I couldn't be more pleased with License Tom and their customer service. The product is authentic and as advertised, they warned me about a likely issue, customer service responded quickly and clearly, their advice was easy to follow (and worked the first time!), and they were super helpful throughout. It's exactly how you want this sort of thing to work, and that can be pretty rare thing. They're obviously a special company.
