Microsoft Outlook on the Mac App Store - no option for in app purchase Microsoft Outlook on the Mac App Store requires an Office 365 subscription. There is supposed to be an option to subscribe using an in app purchase - I want to use this option.
However, the darn thing never gives me any option to do so. I initially tried to activate using an old account, but that account does not have an Office 365 subscription.

I have tried in vain to remove every trace of Outlook and start over - I've removed the keychain entry for &quot;Office,&quot; and removed more or less everything with &quot;Microsoft&quot; in the name in ~/Library (including the obvious stuff in ~/Library/Containers, /Library, and /System/Library. I've removed the application from /Applications as well, emptied the trash, and rebooted.
I have tried clicking &quot;Stay Offline,&quot; to open outlook, and then open its list of accounts - there are none. I have also tried using outlooks profile tool to remove the existing profile, to no effect.
But once I install the app from the Mac App Store, the blasted account is still listed. I do not have any other office applications installed.
So, how can I either (a) reset outlook completely so it doesn't show this account (and thus hopefully gives me the option to use an in-app purchase to subscribe, or (b) force outlook to activate using an in-app purchase?
For any future readers, the Mac app store version of Outlook simply does not work the way I expected. You will not be given the option to subscribe using an in-app purchase until after you have created or logged in with a Microsoft account.
Once you have logged in with a Microsoft account, then will you have the option to subscribe using an in-app purchase.
