Delay installing it, if you can.
MS has pulled the update
I would recommend stopping the Windows update service and nuking the contents of C:\Windows\SoftwareDistribution\Download (patches/updates get downloaded there first before installation)
I've had to stop using Office for Yahoo mail. I'm now using the built in windows email which had no problem setting up the account. Even using the exact same settings for Office as Window's settings, I'm getting no joy so I'm hoping a patch may fix it. Other than that I will have to contact Microsoft. As I said, it's no biggie but damned annoying when something that should work, did work and is entirely down to upgrading Window. Just my OCD...
Are you using Office 2016 (via a 365 subscription)?
If you are, go into Outlook, File tab, click Office Account and check for updates?
Sorry but I have to ask, is this on a laptop that you frequently just suspend rather than closing down, if so, try a restart as the MAPI process could be on the blink.
