Powershell script: Outlook To Exchange connection test

Outlook can lose connection with Exchange for various reasons and even if it happened once, it still can impact the business. To help administrators identify the core of an issue I wrote this Powershell script.
The script is designed for Outlook 2013-2019 clients that connected to Exchange 2016-2019 by "MAPI over HTTP" protocol.
Before start the script change two variables:
$Exchange = "exchange.test.local"
$SMTPDomain = "test.local"
The result is presented as an HTML page.

Windows 10 please STOP reboot my PC/Laptop

Most of all in Windows 10 I hate preinstalled games and that it rebooting my laptop as he wants (most often at night and mostly without any notification).
To prevent it I have found a simple solution - disable "Reboot" task. But everything turned out to be more difficult. Windows still reboot my laptop (the screenshot below shows that task started even it disabled ("Отключено" in Russian)).

Therefore I decide to write a powershell script to prevent it once and for all.

Exchange: How to reliably determine that a user is logged into mailbox?

Sometimes (for example while migration users are from another email system) there is a need for reliable determination that a user is logged into the mailbox (using Outlook or OWA).

The simplest answer is mailbox's lastlogontime (Get-MailboxStatistics). But it turnes out to be not quite true.
Attention! The attribute "LastLogonTime" of user's mailbox filled and updated when another user opens user's calendar.

Finally, I found 4 criterias which help to reliably determine that a user is logged into the mailbox.

1. "lastlogontime" (Get-MailboxStatistics) - necessary but not sufficient attribute.
2. "Languages" (Get-Mailbox) - this attribute filled when user entered into OWA and sometimes filled when entered into Outlook.
3. "WorkingHoursTimeZone" (Get-MailboxCalendarConfiguration) - this attribute filled when user entered into OWA and sometimes filled when entered into Outlook. Deffault value - "Pacific Standard Time", so you can use it only if users are in a different time zone.
4. "Quick Step Settings" (Get-MailboxFolderStatistics) - this is not an attribute, it is a checking for the presence of a folder "Quick Step Settings" in the mailbox, because it appears only when you open/configure Outlook.
