I prefer not to do that.įortunately and finally I found a simple solution. I troubleshot the SMTP server countless times and did a few other activities short of getting under the hood on the OS. I really don't know.Īnyway, here's my solution. It's possible my university's mail server settings for my uni account is interfering with my other accounts server settings each year I update it. I don't know why but it all seems correlated that when I use multiple accounts to compose emails and or happen to switch off an account or change the from address it's triggering a bug with the server selection for each account. My hunch is this issue arises when switching between the 'From' email address drop-down list when creating a new email and or in conjunction with switching on or off mail or any mail accounts within the same session of using Mail. The following relates to my being on MAC OS Sierra 10.12.3 If anyone is still having this issue, I share your pain. (Mid 2010 model)ĭid I miss anything? Any ideas to help me resolve this? The SSD makes the MacBook Pro feel new again. I completed this and still got the same error with not being able to send email. I also wanted to note here that I was also in the process of updating my MacBook Pro with a new 250GB SSD. When I clicked on the .com (hyperlink, screenshot 1 at the top), Safari opens and it says Safari could not connect to server.Ħ. This included all my accounts associated to my Mac mail account. Removed my email account from Mail client and put it back on. Apparently it goes to the same place as the iCloud listing.ĥ. Created a new SMTP out mail connection (Email Out - (Offline)) using information I got from the forums. I also got this pop-up during this processes.

Under System Preferences > iCloud > I signed out of iCloud > Restarted > Signed back into iCloud.

Under System Preferences > iCloud > I deselected the Email from the iCloud > I then reselected it.ģ. turned it (MacBook Pro) off and on again.Ģ. Here are some of the steps I took: (All of these did not resolve the issue).ġ.

The iCloud (offline) is the original and the Email Out (offline) is one of my troubleshooting steps. When I try to send an email, it goes to my Outbox and sits there. This appears to be a known problem but the solutions that I have tried that were mentioned in the forums or internet do not resolve my issue. But now I need to send more detail emails and I can't because the mail client will not send. At first it didn't bother me too much because I just used my phone to send email when needed. For the past week I have not been able to send email.
