Support for TLS 1.0 encryption ending

Did you know that support for TLS 1.0 encryption (which dates from 1990) ends this month, and Office 2010 doesn’t support anything later?
Why does this matter? It matters because there are several known exploits for this old encryption standard, which means that a determined hacker could “sniff” your login passwords. And a hacked email account can be used to reset the password on other online accounts, so there is a strong financial incentive for hackers.
The solution, as always, is to keep your software updated and make sure you have good backups.
