Outlook 365 unable to send email via IMAP anymore

Ok, so here we have a Windows 10 with Outlook 365 where an Linux email server account is configured (Postfix / Dovecot). Since around mid-October 2022 sending email fails. OK, I tried to adjust the submission ports (587, 465 …), but to no avail. Outlook either says that this authentication method is not supported, or, if you select „Auto“, that none of the available methods are supported. After doing some googleing, I came across a very short note that some recent security patches might be responsible.

The link says the following:

Workaround
remove patches:
win11: KB5018427
win10: KB5018410

Since I have Windows 10, I went to remove security patch KB5018410, did a reboot of the Windows machine, and voilá – Outlook was able to send email again.

To uninstall the patch, just search for „Windows Update“, select „Update History“, look for KB5018410 and delete that patch. Also hope, that Microsoft comes up with a resolution of that issue soon as I don’t want to miss a security patch only because it breaks Outlook 365.

Dual Monitor Setup with Two Different Backgrounds in Windows 10

Ok, this is rather a gimmick, but this was the wish behind: I have a dual screen setup in my office. Normally, the same desktop wallpaper would be shown on both displays. Now I have a list of internal telephone numbers and wanted to display those only on one of the desktops. I created two different wallpaper images, one with the phone number list, the other without. This is the way how you can display two different images without any additional software:

  1. Copy the background images into the path: C:\Windows\Web\Wallpaper\Windows.
  2. Now use the CTRL key for multiple selection to select both backgrounds.
  3. Right click on one wallpaper image -> Choose „Set as desktop background“.

The selected wallpaper images will be stored under:
%USERPROFILE%\AppData\Roaming\Microsoft\Windows\Themes
as:
Transcoded_000 and Transcoded_001 without extension

If you want to swap the images, just rename 0 to 1, 1 to 0. Sign out and sign back in or right click on desktop and select: Next desktop background.
