Hi I'm 78.8.0 on Windows 10 and for quite a while the auto update functionality hasn't worked. I've just sat down to investigate and checked the last-update.log to see what's going on. The log seems to indicate that the Inbox file doesn't exist but I have confirmed he file does exist and it's 2.2 GB in size. I've tried repairing the inbox and compacting but it still doesn't work, any suggestions on how to resolve?
