Hello. My name is***** to JustAnswer. I'm reviewing your question now, and will post back with your reply momentarily.
Can you tell me how you are accessing your email? are you using a web browser? (if so, which one)
or are you clicking on the email client icon on the mac itself that you added email to already?
What does your email end in, @gmail, outlook, yahoo etc?
Try this to start please. I take it you are using 10.12.1 Sierra ? Shut down and force close if necessary.
Shut down your Mac.Locate the following keys on the keyboard: Command (⌘), Option, P, and R.Turn on your Mac.Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.Hold these keys until the computer restarts and you hear the startup sound for a second time.Release the keys.
Open your finder ( magnifying glass ) type in disk utility, and launch the disk utility application.On the left side of the disk utility window, click your mac hd, then at the lower right hand side, click repair permissions .
if yours has first aid,
You can follow this guide for this.
Then open your email and tell me what happens.
Please rate the 5 stars at the top of the page to close out this question as it is the only way i amcredited for the work done with clients. Or, reply to continue if further troubleshooting is necessary.~Franklin
Were you able to get to the first aid?
To start your mac in safe mode, start with the mac turned off. Press power then *immediately* press and hold the left shift key on the keyboard. Keep holding it till you hear the startup chime, then release. That should start you in safe mode.
Then follow that guide i sent and tell me if you can get to first aid options and use them?
what is the make/model of your computer?
Okay, you can get to your recovery mode here;
This will show you versions of macbook pro and how to start in recovery mode.
This one pertains to your first aid a little better:
How? From in the program or did you take out something like this; ~/Library/Mail/V3/Mailboxes
Delete the mailbox “Outbox.mbox” and reopen Mail.
Can you click on the apple sign, help about mac and tell me your version and everything you see there?
Try this for me please:
Then try this if that doesnt help:
1. Deleting the email account in preferences, and create a new account to see if that fixes the issue.2. Go to Preference and select Accounts > select Account Information > find SMTP Server > select option "edit STMP server list" > reset all the settings in the list.3. Uncheck mail extensions at Mail Menu > Preferences > select Extensions.
