Gmail not working

If you don't have other computers and only your phone is connected, you might need to setup your account again. Did you try the suggestions in the link I provided?

To put Mail into work offline mode, use one of these options. I don't have an iPhone so can't help there.

1) Control-Click (Right-click) and select Take Gmai Offline.

2) Customize the tool bar and put the work offline icon in the toolbar.

The server returned the error: Too many simultaneous connections. (Failure)

If you are connecting on other devices, Gmail could see this as too many connections. Change schedules or put some devices into "Work Offline" mode.

Use Gmail with Mavericks Mail

I have exactly the same problem lately. I have tried to delete Google account and then set it up again - no help.

Don't have two-step verification.

Changed password - didn't help.

Tried both with Idle and without.

When logging in directly on web-site mail.google.com with the same password - no problem.

The Mail says "Can't connect to IMAP server using Password verification" and "Too many simultaneous connections" both on iMac and iPad.

After some time works just fine, and then again the same problem. Many times per day.

I understood not many people have this issue (my wife have google imap on macbook - works okay) so not much hope it will be solved for me soon

If I go into system preferences and change the passwod fro there I can get my account to connect. system preferences-internet accounts-gmail-details, then re-enter password. I also worked with my comcast account but it does keep happening occasionally.

"Too many simultaneous connections" means that you have too many devices trying to connect to Gmail at the same time. Try putting other accounts into work offline mode and see if that helps.

If you have multiple users frequently accessing the same account or more than one IMAP client accessing Gmail at the same time, you may reach a connection threshold and receive the error message, 'Too many simultaneous connections.'

Gmail currently has a limit of 15 simultaneous IMAP connections per account.

Please note that your mail client may actually open multiple connections in the background. This means it's possible to reach a connection threshold simply by using only two mail clients to access the same account at the same time.

If you often use multiple mail clients or mobile devices with the same Gmail account, we recommend closing and/or signing out of any mail clients you're not actively using.

Not at all. I only have Mail on my iMac and iPad.

On iPad I check mail once or twice a day and close the application right away after using.

iMac Mail checks for new mail Automatically (tried to choose Every 5 minutes - still the same).

And there's a message on iMac Mail - "too many connections.." almost constantly (even though truth be told it recieves new messages despite the warning).

When I open Mail on iPad for the first time a day it says "can't connect to IMAP using password verification". That means the maximum number of simultaneous connection already exceeded? That means iMac Mail does it because only iMac has been working non-stop lately with Mail opened.

Why does Mac OS Mail have more than 15 connections simultaneously? And why only few users have such a problem. I am sure thousands people use Mail with Gmail account and looks like not many complain.

Might it be the Mail connects to the server, checks mail and then fails to close the connection? And then later rechecks again with new connection and again doesn't close the connection? So theoretically there are 15 simultaneous connections after 15 minutes.

If that's the case why only my Mail (and Rothrock's)? How can I fix it?

Remember, few months ago there was an issue when Mail stopped receiving new mail after some time and after you quit and reopen Mail again you receive the mail. I had this problem as well. Maybe it's connected somehow.

Thanks for the discussion,

I have the same problem, and it has suddenly happened. I have MC Pro Retina, iPad, iPhone. 2 Step Veification. In the past I would get the alert on my phone or ipad that the password was incorrect for gmail, but the email would come anyway. Annoying and weird, but not an issue. But now on my computer I am not able to get any Gmail because of this Failure from too many connections alert. Already tried deleting and readding, to no avail.

Any other ideas/ answers?

Strange, I'm signed in (that's how I've been commenting) but as you can see, no option to mark "this helped me"/"this solved my question".

Only the original poster can mark as answered. I didn't notice you weren't original poster. Once a thread gets longer and with multiple posters, it can get confusing.

Thanks for going out of your way to mark as answered.

Sorry to interrupt but it doesn't help actually, at least for me.

If I choose "check every 5 minutes" I still have "too many simultaneous connections" message in about an hour later.

If I choose "check every 15 mins" I have "too many connections" again on the next day.

The longer interval the later you'll get the error but it's still there.

And it's not a solution anyway to check for new mail once per hour or so. I want to get the mail as soon as it's been sent like others do who don't have this issue.

if I choose "check every 5 minutes" I still have "too many simultaneous connections" message in about an hour later.

If I choose "check every 15 mins" I have "too many connections" again on the next day.

Are you checking the account on other devices? You need to adjust the other device's schedules. I know some users use both Mail and Outlook to check the same account. In this case, it's best to put one in work offline mode until you switch applications to check in other app.

If other devices, computers, phone, tablets are connecting this will add to connections to your account.

No, only iMac alone exceeds maximum allowed connections.

If I login to gmail.com and choose "close all active sessions" then the error message dissapears in Mail but after some time again - "incorrect password", "too many simultaneous connections"
