My iCloud accounts have disappeared from Mail

Yesterday everything was fine. Today, I went to reply to an email to discover that instead of my reply email being sent from my iCloud account my personal Yahoo email address was shown. I clicked to get the selection menu to see that all my iCloud accounts have disappeared! I've only been doing innocent user things, so it's not something I've caused.


When I look in Mail > Preferences > Accounts I see that the left window is too narrow to see the full name of each account, which is odd. All my icloud addresses have disappeared except for the one I normally use where there is an entry. "Enable this account" is ticked, the description in correct but the Email Address field is blank. I can't edit the feld.

I get a pop up window that I can't edit:


What has happened? I haven't installed any new software or anything.

I used the email address as the description (I don't need a separate name for it). The problem is that the email address that was also in the "Email Address" is no longer there, and the field is uneditable. Remember it was working fine yesterday and I haven't changed anything.

1 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.


2 - Safe Mode will also eliminate Third Party Software, extensions and drivers from loading. It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance 


3 - Does the issue present in this mode ?


4 - Sometimes a Safe Boot followed by a Normal Boot will just put things right.


5 - If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.


6 - If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.


7 - Download the Application Etrecheck directly from the Developer.


This is a Diagnostic Tool that makes no changes to the computer.


It makes a coherent and readable inventory of both the Hardware and Software used on the computer 


The application is free or paid from added features. 


The Report will Not Reveal Any Personal Information.
