Cannot Send or Save in HTML Format V10.4.4.4756

V10.4.4756 disregards HTML Format and converts all email (Saved to Draft or Sent) to Plain Text. Reads received HTML Format email okay.
V10.4.4195 works fine.
Downloaded V10.4.4756 again and tried Repair. No joy. Error message: File ‘filOTMt4Wj.G..U5PRs.PBUTYhHA5cw’ cannot be installed because the file cannot be found in cabinet file ‘MailClient.cab’.

Downloaded and installed latest V10.4.4842.0. Installed okay. No error message. Same issue still exists. Italic and strike through still convert to Plain Text (no Italic, no strike through). Ran Repair. No joy. New Mail Compose and Reply still set to HTML.

Italic and strikethrough works OK here.
macOS Tahoe 26.4, Beta, eM Client 10.4.4756

Hi, we were able to reproduce the issue and our team will work on preparing a fix. Thanks for the report!

Copy that. Thanks. I should have advised the OS is latest version of Windows 11.

Copy that. Thanks. Much appreciated!

I just noticed the extra “.4” typo on my original post title. Sorry. My bad.

I rercommend using this version:
https://www.emclient.com/dist/v10.4.4867/setup.msi

There’s a second new version released today that doesn’t show in the Release History? Is it a Beta version?

It is now an official build in the release history. This last build resolves this issue:

Confirmed V10.4.4867 also resolves the strikeout and italic issue. Thanks.
