Can't add email accounts to Apple Mail

Don't know the exact situation, but Google now requires Apple users to register their email account passwords, etc., via Safari. Bizarre.

This is the same issue I have. Any resolution?

That's a really odd dialog, which is to say I've never seen it before.

Please determine if the same problems occur in "Safe Mode": Use safe mode to isolate issues with your Mac - Apple Support.

In reference to the Outlook account, I was having the same issue, not being able to add it to the Mail app in my MacBook Pro.

In my iPhone X, it worked fine.

After trying various solutions, I managed to add to the Mail.

When entering the initial information , such as email and password , I used the password created in the < AppPassword> .

Probably, because I had the two factor authentication enabled....

Give it a try!

This is exactly what mine has done - last Friday. One of the Gmail accounts in mail is still working fine but my main Gmail won't connect. I removed it and now can't add it as above? Tried changing the password but no progress.

I was on to Apple Support for an hour last night and they only told me to do everything I had already done. I've gone through safe start up and no issues reported. This is now driving me mad!

I have a similar issue. I use Apple Mail on an iMac, MacBook Pro and iPhone. I have several mail accounts that work fine on all three. However, I have a few accounts with an organization that I belong to. I have been able to add all of them to my MacBook but my iMac rejects all of them. I have a couple on my iPhone but just tried to add a new one and it asked for a Username under Incoming Mail Server (though not under Outgoing...). I don't know of a Username, and didn't need it when I added this account a few minutes ago to my MacBook Pro.

Wish I could provide more insight… I used SiteGround's profile script that ended up in the System Preferences app. Ran it from System Preferences and it worked. I just updated to Mojave today and ran a test sending/receiving with that SiteGround email account, and it was successful.

A week ago I created an email account for my client who was on Mojave, and the profile script for his account worked…

There's also an additional step whereby you have to "verify" -- authenticate with a password -- Gmail accounts by first opening the Safari browser and then entering your ID and passwords there. (I got notifications that directed me to the Mail -> (iCloud) Accounts page where I learned about verification.) How this makes sense, given that Gmail -> Google -> Chrome browser, I can't fathom. But it worked for my Gmail accounts, made them functional.

My most grievous problem is getting the IMAP and SMTP servers lined up and having them remain in synch with the mail accounts, since my various email hosts use different protocols for IDs, PWs, and how mail is served to clients (like Apple Mail). Far too often after trying to send an email and failing I get that unnamed warning box that (a) tells you an email wasn't received because it was rejected at the receiving end or never sent; and (b) instructs you to visit another unnamed window and tweak all your SMTP lists and settings, not just once, but sometimes repeatedly -- until you freak out, delete all your mail accounts, and start all over again.

Weird that the warning box and SMTP window are still a part of Apple Mail into the fourteenth-plus iteration of OSX! Can't email be set up some easier way that doesn't often tie up one's Mac, so you have to reboot (as happens often)?

Hi Helbee,

Did you get this figured out? If so what did you do? I have the exact same problem with my siteground email.

Cheers

p.s no issues on Mac, iPad or iPhone!

It’s not even the beginning of a solution. I have two iMacs one caught this bug the other I can add and delete accounts all day.
