Apple Mail Tech Support
Sunday, November 29th, 2009My Apple Mail went bonkers when I tried to delete a massive amount of emails and tried to send an excessively large email via my Google IMAP account. I couldn’t get or send new emails and received this sort of message:
Some actions taken while the account [your-account-name-here] was offline could not be completed online.
Mail has undone actions on some messages so that you can redo the actions while online. Mail has saved other messages in mailbox Apple Mail To Do in On My Mac so that you can complete the actions while online.
Additional information: The IMAP command APPEND (to Apple Mail To Do) failed with server error: Invalid mailbox name..
Option #1 from this post seems to have solved the problem:
- Make sure your Mail program is closed
- Open Macintosh HD (double-click on it)
- Select your Home folder (it will be on left nav bar with the picture of a house)
- On the right side of the window, double-click on the “Library” folder (to open the folder)
- Double-click on the “Mail” folder
- Remove (move to the trash) the “IMAP-youremailaddress@here.com” folder
- Close everything and open Mail to confirm it has been fixed
