How to fix import errors in the Mail application?

hello


The application does not work

When opening it, he requests the import of e -mails

In the end, a message appears "The Import Failed"

Because of the area of the device, knowing that the area is more than 250GB unused


I hope you help me solve the problem without losing my email and thank you

I followed some of the information in this thread and fixed it very easily by simple unchecking Mail from all the Internet Accounts in System Preferences except for iCloud. I started Mail it started instantly with only 257k and then I right-clicked on the iCould inbox folder and selected Sync Mail with iCould. It went to work and did its thing. Lastly I brought back all my other internet accounts online. Easy peasy :)

I get the same "Import Failed" message. I have 1.95TB of unused space. Got new M1 Macbook to replace old 2011 Macbook which was using Outlook -- which now requires a subscription. I copied everything to new M1 Mac via TimeMachine. I don't know what the M1 Mac Mail thinks it needs to import. Is there something somewhere I can just "blow away" and start over? I do still have access to the old 2011 Macbook...

Ok I need to confirm that starting up in SAFE MODE (hold down shift when booting up) will totally fix this.


  1. Deactivate mail in ALL internet accounts in settings. That will import the fewest number of emails just to get the app running
  2. Boot up in Safe mode (hold shift)
  3. Start up mail and import to get it running
  4. Reboot normally
  5. Go to settings and turn on all of the internet mail accounts
  6. Let it buld each account again
  7. Drink a beer and rejoice


LMK if this works.
