SSL errors after zimbra upgrade to Patch 8.8.15_P42

Post by adamdudzik »

Hi,
after updating zimbra to Patch 8.8.15_P42, I have problems with Outlook working on Windows 7 computers.

In the Zimbra Connector logs:

Code: Select all

11-09-2023 14:39:51.399 |||O16 05DC MAIN      9C8||| ### WARNING ### Failed to obtain server cert. Error: 12019 @ Connection.cpp#1869[SaveCertAndCalcFingerprint()]

and that's all. Computers with windows 10 and 11 work without any problems. Is there any workaround or do I need to update Windows?

You might not have installed the Microsoft update that allows TLS 1.2 instead of TLS 1.0.

You should definitely upgrade. Windows 7 is End-of-life and hasn't received security updates from Microsoft for well over 3 years now.
Even if you purchased an "Extended Security Updates" plan, it ran out in January 2023.

Yeah, I know but we have an application that only works under Windows 7 and that's a big problem for us. It's not up to me, I just have to maintain it :(
