For the last 25 years I've used Rocketmail (now part of Yahoo) via webmail and Windows 10 Mail without a problem.
Today, I've installed Microsoft 365 as a member of a family group.
While looking at Excel (NOT Outlook) a window appeared and KIS 21.2.16.590(b) Web Anti-Virus reports:-

Event :    SSL connection with invalid certificate detected
User type :    Not defined
Application name :    EXCEL.EXE
Application path :    C:\Program Files\Microsoft Office\root\Office16
Component :    Web Anti-Virus
Result description :    Blocked
Object name :    autodiscover.rocketmail.com
Reason :    Invalid name of certificate. Either the name is not on the allowed list, or was explicitly excluded.


Advice welcome!

Sorry no screen image.

The Kaspersky error message appeared while I was looking at the opening screen to MS 365 Excel.

I have not made MS 365 Outlook the client for any email service.

At present Rocketmail is accessed either by Windows 10 Mail (that’s the client that come fee with Win 10 or Webmail.

Hello @wgcuser

Thank you for posting back. 

  1. What does “Sorry no screen image” mean? 
  2. Is the certificate issue replicable?

Thank you:pray_tone3:

Thanks for your posts. On reflection, perhaps what I encountered was MS 365 trying to be helpful having assumed that my Microsoft Account Login was a regular email address frequently used and tried to setup MS 365 Outlook to access it? Only to encounter a problem. - see Wesly’s post.

Who knows ??? :smile:

Further to this, I have used:-

Settings > Network Settings> scroll down to Manage Exclusions> Add autodiscover.rocketmail.com > Make Active > Save > Confirm Change

Re-Boot

So far so good.

Hello,

That’s a temporary solution. Not a permanent plan. Not be safe. All the website list in this exclusion list will not be scaned by web-antivirus. If the website has been infected some malicious JS file or shellcode. Web-antivirus will not block them.

You can do a test. Set “secure.eicar.org” in that exclusion liet and acess https://www.eicar.org/?page_id=3950 to download EICAR TEST File. This file will download successfully if the browsers itself url safely filter doesn’t work.
