Is it possible to store my local Mail folders (i.e. those which Mail actually stores on my Mac in: ~/Users/*username*/Library/Mail/V5) on the iCloud Drive and make them accessible from all my iCloud devices?
and how can this be done? For instance using aliases in ~/Users/*username*/Library/Mail/V5 which point to the corresponding folder within iCloud Drive?
Click on Go on top menu bar , hold option key click on > library > select mail folder > right click on mail folder there itself > click on copy mail > right click on the desktop > click on paste item .
Entire mails are copied to V5 folder and V5 folder will get saved on the desktop .
The V5 folder is never saved on iCloud drive and will never sync with other Mac , if other Mac is also signed in with same Apple ID and password , of course mails can be transferred to from one Mac to another Mac , so the option of no and yes leads to no only , as you said in the last V5 folder and its subordinate folders can be corrupted or iCloud Drive will not accept it .
No but yes.
You "could" manually copy those folders to your iCloud Drive folder on your Mac and they would be stored in iCloud Drive. I would not suggest this.
There would be no syncing and it's possible the folders could be corrupted in transit. It is not an advocated usage of iCloud.
Sometimes things that are achievable are not sensible.
No .
