Upgraded my Macbook 15 retina to Yosemite but mail cannot connect to IMAP server.
SMTP seems OK.
I've deleted account and re-entered it. It IS correct but it refuses to connect.
Says Trying to login to this IMAP account failed. Verify that the username and password are correct.
Any ideas?
iPhone 4 and iPad Air mail working OK still.
Mac mini, OS X Mountain Lion
Same for me but 3 years later it's likely another issue... I'll open another thread
This problem still exists three years later!
I'm not having much success after trying instructions above.
OS 10.12.6
Reentered my password in accounts IMAP and SMTP yet refuses to play ball. To be sure I changed my password on the ISP, reset it on the iPhone and iPad which both worked. Reset it again on the MacBook but still it doesn't work. Keeps saying mail cannot connect enter the password. The password is 100% correct as are the other settings.
Seems like Yosemite has screwed IMAP mail as SMTP is working.
Neither. It is Fasthosts. But it's not the ISP as that still works on iPhone and iPad. Just tried this which was posted in another thread and it worked!
For those of you having email password issues, I'd suggest:
1) Close your mail client (i.e. Apple Mail, Thunderbird, Outlook, etc).
2) Launch "Applications" > "Utilities" > "Keychain Access.app"
3) Select "login" from the sidebar top left area, then select "Passwords" in lower left area
4) Click into the Search box in the upper right and search for your ISPs server names. For example, type "aol" or "google" or "comcast", etc.
5) Look through the search results for password entries related to your SMTP (outgoing) or IMAP/POP (incoming) mail servers. Select them and delete them.
6) Open your email client and try to receive mail, and then to send mail. You should be prompted to enter your mail username and/or password.
Hopefully this might fix issues for those of you using mail clients that use Keychain for credential storage.
Hmmm I think I spoke too soon.
It does work when I check those settings, but the settings don't stay checked the next time I open the dialogue.
I tried deleting the smtp entries in Keychain Access too. No joy there either.
Yes, the fix does work and stays working. Mail >> Preferences >> Accounts; get down to the spot where you can see the little button
"allow insecure login" and click it. Then everything is okay.
I have a fasthosts IMAP email that did the same thing
In the email account settings, check "allow insecure settings" and also uncheck "Automatically detect and maintain account settings"
Seems to do the trick
I don't have the answer but I do have exactly the same problem
Yes, iPhone and iPad are fine, but the Yosemite upgrade has destroyed access to IMAP mail accounts.
Same here...
(Mac Mini running OSX Server)
Found a solution: checked "allow insecure authentication" in the Mail >> Preferences >> Accounts
doesn't work for me
Doesn't work for me either. I did manage to get Thunderbird to work but now that is having the same problem. Yosemite is broken lots of people IMAP it would seem!
Is this a Gmail or GoDaddy account?
Cannot login to IMAP after upgrade
