"Make sure Force HTTPS option in Global Configuration is disabled."

Why so? There are a lot of websites with SSL.

[SharkyKZ]

The issue is reproducible only when Force HTTPS is disabled.

[Sulpher]

The issue is reproducible only when Force HTTPS is disabled.

I opened the administrator panel via http:// (no SSL) and Force HTTPS is set to None.
However, the issue occurs.
Then I opened the back-end via https:// and set Force HTTPS to Entire site.
The email is consists of correct URLs and there is no issue described above.

The conclusion: the problem could happen with the sites without SSL...

[SharkyKZ]

Yes, the issue occurs when Force HTTPS is set to None (i.e. disabled).
