Current-era Microsoft continuing to push the boundaries of consent.
Microsoft Edge is a good browser but for some reason Microsoft keeps trying to shove it down everyone’s throat and make it more difficult to use rivals like Chrome or Firefox. Microsoft has now started notifying IT admins that it will force Outlook and Teams to ignore the default web browser on Windows and open links in Microsoft Edge instead.
Outlook on windows 11 absolutely has ads in the inbox, though I understand you may not have windows 11 or installed the free outlook through the windows 11 upgrade.
“It’s fine” was always my experience when I used outlook through work. Thunderbird can also be integrated with microsoft programs, i’m not sure why its interoperability is such a standout feature for you. But having advertisements masquerading as unopened mail within my inbox is absolutely not fine.
