Outlook 2019 Security Alert for "Certificate"
When I start Outlook, it starts to check send/receive mail...but I typically get the this security alert. (File is attached) I have tried "install certificate" for the "current machine"......
I would check if this is somehow related with your network. Anyway, you can disable the warning but probably that's not the best idea. Have a look into: https://support.microsoft.com/en-us/help/3211279/outlook-2016-implementation-of-autodiscover
If you want to disable it here is the regkey:
Key: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\AutoDiscover
Value: ShowCertErrors
Default: 0
Data: 1 = Show certificate warnings/errors; 0 = Don't show certificate warnings
If you want to disable it here is the regkey:
Key: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\AutoDiscover
Value: ShowCertErrors
Default: 0
Data: 1 = Show certificate warnings/errors; 0 = Don't show certificate warnings
You're right, fiddling and disabling warnings in the registry are probably not the best idea.
I know this network (my large employer) is secure, I wish there was a better fix or workaround....
- I meant to say something related to the network (DNS, proxies, firewall...), not that it isn't secure.
Take a look into this article, if you haven't done it yet: https://support.microsoft.com/pt-pt/help/2772058/the-name-on-the-security-certificate-is-invalid-or-does-not-match-the
Otherwise, I guess the best way to have it sorted out is opening a support ticket with MSRicardo Viana
