Microsoft 365 / Outlook No longer opens after Windows Update (7/15/2020)
Today a Windows Update installed and I restarted. KB4560366 and one other. After this Outlook won't start. It opens to ask for profile selection, then I click ok, and it disappears. No proces...
Run this script in powershell to roll back the version of microsoft office. This worked for us:
Set-Location -Path 'C:\Program Files\Common Files\microsoft shared\ClickToRun' ; .\OfficeC2RClient.exe /update user updatetoversion=16.0.12827.2047
At about the same time I face the problem. It gave me no sign of update yet it cannont open!!!!!
Same problem - specifically after the Win10 2004 - had to rollback in order for Office 365 to work. Personally I'm waiting for next Windows 10 version to upgrade. Also in the last couple of days my Office 365 Outlook won't connect with a Gmail account when everything was working just fine previously. Concurrently on another computer where I have Office 2019 everything works fine with the Gmail account. I was able to use Windows Mail client to connect to Gmail as a work around. Microsoft probably won't admit to this boo-boo though.
