Stopping Apple Time Machine Encryption

When setting up a hard drive for Apple Time Machine backups in OS X or macOS, if you enable the  encryption option the drive may perform this incredibly slowly, sometimes taking days to encrypt even a small percentage of the drive.  

Provided you are running a version of the operating system from 10.9 or newer (Mavericks through to Big Sur) then you can stop the encryption process running by entering the following in Terminal and save your hard drive from failing due to continuous access.

diskutil cs revert /Volumes/drive_name -passphrase

To find the drive_name then type diskutil list and use the Volume name. 

When you enter the command you will be prompted to enter the passphrase you set when enabling the encryption.

Outlook (2016/365) warning "The properties of the message have been changed. Want to save your changes to this message?"

This warning/notification appears generally when replying to or forwarding an email message with or without an attachment. For some, it has appeared with new messages too.

Reason: In this case, the cause relates to an 'Add-in' from Adobe and disabling this can provide a cure.

Open Outlook and select File > Options > Add-ins and select Go (see below):

The ‘COM Add-ins’ options box (see below) opens and in this, find and uncheck the ‘Adobe Document Cloud Outlook add-in’. Select OK and then close/re-open Outlook and test with an email that has an attachment in particular

NOTE: as I don’t have Acrobat installed, the add-in does not show and also, it may require other Adobe add-ins to be unchecked should the problem persist.
