Mac Mail very slow in and out

I upgraded to Yosemite a few weeks ago. ever since my email has been painfully slow connecting to the iMAP server. Messages will sit for hours in my outbox, and attachments take forever to download. I have tried the offline/online work around. Makes no difference. I try quitting and re-opening mail, no difference. I am now re-building my mail boxes but the speed or lack of it in downloading the messages back from the server seems soooooo slow. Any other ideas anyone please??
Its like trying to run through treacle when you need to get on with your work and you find that emails you need s response to are stuck in your outbox!!

Mac Mail very slow when waking

Hello
Mac Mail is very slow on my machine, just stalls and gives me the spinning wheel for several minutes. Usually it is when the machine has woken up; it appears that it is trying to do background tasks (like fetching mail) while this is going on but I am unable to switch to Mail for quite a long time. I sometimes see notifications of new mail in this period, equally it sometimes shows in Activity Monitor as "not responding" (although if I wait it eventually comes back).
It is runnning on a brand new MBP retina, lots of RAM, disk and processor available.
It collects mail from four mailboxes, three of them are Exchange and one is IMAP. None are massively high volume, kind of normal to low usage for the average person I guess. I did rebuild the database a while ago, but it just lost lots of mail which then needed to be slowly re-downloaded. I gave up on Outlook (on my previous machine) for being generally crashy, dysfuctional and annoying but now Mail isn't far behind.
Contacts, which I just leave open in the background quite often, also seems to be having trouble staying alive. Often "not responding" and requires a forced quit.
Any suggestions?
Dominic

Please follow these directions to delete the Mail "sandbox" folder.
Back up all data.
Quit Mail.
Triple-click the line below to select it:
~/Library/Containers/com.apple.mail
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu. A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selected folder — not just its contents — to the Desktop. Leave the Finder window open for now.
Relaunch Mail and test. If the problem is resolved, you'll have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Post your results.
Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.

Mac Mail Very Slow (Spinning ball)

Hi -
My Mac Mail has gotten very very slow lately when first opening the app, or returning to the app after a long rest.
The ball starts spinning and it takes about 2-3 mins before I can use mail.
My mail database is very very large. 20GB, so I assume that is part of the problem. I did rebuild but that didn't seem to help.
Any ideas on how I can handle that, other than dumping my archive?

Please follow these directions to delete the Mail "sandbox" folder.

Mac running very slow during and after downloads (even if they are just small docs)

Hi,
I'm getting very frustrated with my MacBook. Whenever I download something, no matter how small the file is, the MacBook really slows down to the point that it is impossible to work on.
Any ideas why or what I can do to fix it would be much appreciated please.
Thank you!

Thanks very much for getting back to me, really kind of you. I'd never done a system check before - here are the results:

after a restart it works for a time, but always slow. I went to the Applestore this afternoon and the made a check and said it would be the logicboard and they would have to change it for CHF 600 and it would be ready in 10 - 15 days

After upgrading to mountain lion my mac is very slow?

Hello
After upgrading to mountain lion my mac is very slow
It was starting in 10 seconds and shuting dow in 5 seconds and now it's taking more than one minute to start it or shut down it and everything is slow
why????????/
Thanks

First, back up all data immediately, as your boot drive might be failing.
Take these steps when you notice the problem.
Step 1
Launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 2
You must be logged in as an administrator to carry out this step.
Launch the Console application in the same way as above. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Post the 50 or so most recent messages in the log — the text, please, not a screenshot.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into a message.
Important: Some personal information, such as your name, may appear in the log. Edit it out before posting.

Since downloading Yosemite 10.10.2, emails are not automatically downloaded.I have to either click on Get Mail or click in and out of mail inbox.

Since downloading Yosemite 10.10.2, emails are not automatically downloading. I have to either click on Get Mail or click in and out om mailbox.
It's very frustrating as it does not happen on my iPad or Iphone.

Howdy welcon,
It sounds like your Mail application is not checking for mail automatically anymore after updating to 10.10.2. It seems to me that the setting for this may have reset, or changed at some point thereafter so I would check the preferences for the Mail application:
General preferences - Mail Help
Check for new messages
When Mail gets new messages from the mail server. By default, the option is set to Automatically (Mail varies how often it gets messages, based on whether your Mac is plugged into an electrical outlet).
An IMAP account may get messages more frequently if the mail server supports the IDLE command; make sure the option to use it is selected in the account’s Advanced pane in Mail preferences.
If you set the option to Manually, click the Get Mail button in the Mail toolbar to check for messages. (Whenever you click an IMAP or Exchange mailbox, it syncs with the server, and shows new messages.)
Thank you for using Apple Support Communities.
All the very best,
Sterling

I have a similar problem: I switched from mac mail to Outlook 2011 as the default client, and want to switch back. Mailto links (eg from browser etc) default to Mail. However, when I try to email a Word document as an attachment, it continues to open Outlook. Outlook has a button in its prefs for making it the default client, but I don't see a way to turn this pref off in either Outlook or in Word.

Cured the problem! Reinstalled an earlier version of itunes from oldapps.com (version 10) now everything works as it should. I would suggest that if you are experiencing these problems that you do the same. I must say that it is a brave business decision on behalf of apple to effectively lock out all windows 7 users from their products and sales channels and I can only wish them luck in this very shortsighted policy.

On the bottom of your MBP there is the serial number. Enter it here and post back the results:

Here is a trouble shooting guide. The usual reasons for slow performance are the HDD or third party applications. Boot into the recovery partition and run Disk Utility>First Aid.

How do I stop Mac Mail from sending an unauthorized "out of office" message to a few, not all, my associates

How do I stop Mac Mail from sending an unauthorized "Out off Office" reply to several, not all, of my associates emails? Only happens with me.com mailbox, not Earthlink. Am not getting some important e-mail from brokerage and business associates.

If Earthlink is unaffected it is probably a settimg in me.com. Log into me.com account in a browser such as Safari (will get icloud.com) and select the settings (gear) icon bottom left, and then click on the airplane icon. Make sure vacation setting is unchecked.

Since downloading Mavericks last week my Mac is very slow. Anyone else having this problem? Any suggestion as to speeding things up?

It will help people help you better if you post your iMac variant and Mac OSX version. Please do "About this Mac" from your Apple menu and, in the resulting window, click the "More Info" button. That will give this window:
The model is in the line I've indicated with the red arrow. Please also post the results for "Memory" and "Processor."
DO NOT post the serial number, however.

Very slow broadband and connection keeps dropping

Hello, we have been BT customers since August 2013, after previously being Freeola customers for many years. We live in a very rural area, at the end of the exchange so we are never going to get amazingly fast broadband, we are estimated 1MB.
Previously using Speedtest.net at the beginning of the year we were getting 0.9Mbps, then in May our internet dropped and we couldn't get a proper connection or speed. We contacted Freeola who after doing some tests, said that we had a copper line failure and to contact BT. We did this and the copper line failure issue was fixed, an openreach engineer tested the line and we assumed all was fine. But we were still getting very slow speeds and the connection kept dropping. So we decided to switch to BT in August, we have put up with the slow speeds and dropping connection for 3 months hoping in vain that once we got a stable line the speed would increase and we would be back to were we expected to be.
When we are using the internet, we very often get "Your connection has been reset" errors within our browsers.
This has not happened, so I have decided to come on to this forum in the hope that we can solve this issue before my hair gets any greyer. We have a BT Home Hub 4 so we have not got all the stats that previous HH had available.
Also as we are in a rural area our telephone connection is through overhead cables and as said previously we are at the end of the exchange.
Please see below for the information that I have been able to get:
Home hub stats:
17:28:52, 28 Oct. ( 68.040000) DSL noise margin: 12.00 dB upstream, 9.50 dB downstream
17:28:51, 28 Oct. ( 67.970000) DSL line rate: 448 Kbps upstream, 192 Kbps downstream

I performed the quiet line test which wasn't too bad there was a very slight crackle, but it was with a wireless phone.
Speedtest.net results:

As said previously before the copper line failure we were regularly getting download speeds of 0.9mbps.
Any help would be greatly appreciated.

Hi jacoma,
Sorry to hear that your having issues with your BT Retail services.
You will either be on the ADSLMax (upto 8mbps) service or if your exchange has been BTw 21cn upgraded you maybe on the ADSL2/2+ (upto 12/20mbps) service depending on your line quality and length.
However these upto speeds may not be the speeds you will get as ADSL broadband connections are very dependent on the distance from your property to the exchange and the quality of your line. The further away you are from your local exchange the slower your broadband speed will be.
To enable the community to help you please see the advice below:
Please see Keith's help guide here: Helping forum members to help you, it will go through some checks that are needed for us to help you.
1) Are you in the TEST socket? if not can you please connect to the test socket and repeat steps 2, 3 and 4.
All the below performed in TEST Socket:
2) is there any noise on your line. dial 17070 option2 ,called quite line test, from landline phone. should be silent but slight hum normal on cordless phone.
If there is any noise on your line such as crackling, distictive noise when the phone is connected to the TEST socket and doing the quiet line test then you need to report a line fault to BT Retail by dailling 151. Once the crackling or disticive noise has gone then your broadband should slowly recover.
3) please post adsl line statistics
4) Can you please run a BT speed test (including IP Profile) http://speedtest.btwholesale.com (not beta version)[Best done with a wired, Ethernet, connection] After Quick Test is done you need to click "Further Diagnostics" to get IP Profile.
ADSL Line Statistic Help:
If you have a BT Home Hub like the one below...
Then:
1) Go to http://192.168.1.254 or http://bthomehub.home
2) click Settings
3) Click Advanced Settings
4) Click Broadband
5) Click Connection or sometimes called ADSL (see picture Below)
The direct Address is http://bthomehub.home/index.cgi?active_page=9116 (for bthomehub3.A firmware ending in 1.3)
or http://bthomehub.home/index.cgi?active_page=9118 (for bthomehub3.A firmware ending in 94.1.11)
You will need to copy and past all the adsl line statistics ( Including HEC, CRC and FEC errors). You may need to click " More Details"
If you have a HomeHub 4 then the majority of the ADSL Stats shown in the previous Hubs will not be there.
for HH4 users you can go to hub manager then select troubleshooting then logs and are look for 2 entries together which will show theconnection speed and noise margin for when your HH4 last sycned with the exchange.
There are more useful links on Keith's website here: If you have an ADSL connection, please select this link
cheers
I'm no expert, so please correct me if I'm wrong
