Mail: extremely slow

Hello
Recently my mail app has begun to run really slowly. For example, when I click on an unread message, it takes several seconds for the message to be regestered as read and for the small blue circle to disappear. I have more than 16,000 messages - it that the problem? If so, how do I preserve the hundreds of messages that I need records of without slowing down my Mail app
Very grateful for any feedback
Doug

I had the same problem. Opening Firefox in Safe mode cured it, so I knew it had to be a setting or plugin of some sort....I did all the recommended fixes and nothing changed the typing being real slow and behind when running in normal mode.
What fixed it for me is turning off the hardware acceleration option in Firefox. Here's how: Click on Firefox->Options->Advanced->General tab. Then uncheck the checkbox "Use hardware acceleration when available". Click OK. Hope it works for you. Good luck!

Saving attachments in Mail extremely slow!!!

I can't seem to find any mention of this anywhere! But since 10.5.2 saving attachments from mail is extremely slow. Try an email with many attachments - more than 10. The size doesn't seem to matter. It takes roughly 1 second per attachment. Pre 10.5.2 was almost instant. Problem remains in 10.5.3.
Doesn't matter if I hit the 'save' button or choose 'save attachments' from the File menu.
Other mail programs do not do this. (Entourage, Gayzmail)
I think it has something to with quarantine but can't find any info.

Works here in 10.6.8. Are you using Lion, by chance?

Yahoo Mail extremely slow on Firefox 12

Yahoo Mail works fine in IE9 but is extremely slow on Firefox 12 after applying Java update 7.11 patch. Please advise on how to fix the issue.

Yo soci888! Why are you on Firefox 12? All the cool people are on Firefox 18 now. Time to upgrade and join the crew. Check out this upgrade link: https://support.mozilla.org/en-US/kb/update-firefox-latest-version
Here is another suggested solution from another solver:

Is your Mail extremely slow trying to send to a "group" from Contacts?

I can't believe how long this is taking to just add a couple groups from my Contacts into the To: area of a message in Mail. I've never had this problem with my older 10.6.8 OS. There are about 150 addresses in one group and less than 10 in another, yet, once I type in the group name, everything slows down to a snails pace in Mail and I can't type one letter without having the beachball of death start spinning. This is ridiculous! Is anyone else having these kinds of problems? Generally Mail in Mavericks has been working well for me - the amount of spam has decreased tremendously, but this new issue is a big problem!
Thanks for any insight,
kt

I am climbing the walls with this.
I have to type the text of the mail, then insert the group.
Forgot about changing anything later or adding a second group.
It takes several minutes to change one character.
Activity Monitorshows "Mail (Not Responding)", CPU running 99.9%
Crazy.

Mail extremely slow for an imap account after 10.5.2 combo

Mail became very slow for a non-.mac/non-gmail imap account after I installed 10.5.2 combo. The account works fine from other mail client such as Sea Monkey. It was working fine until 10.5.1. Any hint?

Using INBOX as the path prefix is NOT the "correct way"; the correct way is server dependent. This is further complicated by the fact that servers that fully support the IMAP Namespace extension actually have more than one "path prefix".
On my company's server, we have the concept of shared mailboxes and the company relies extensively on them. If a user sets the path prefix to INBOX, he can no longer see the shared mailboxes, since that prefix limits him only to his personal mailbox hierarchy. So he must leave the prefix as blank in order to see the shared mailboxes.
Unfortunately, 10.5.2 has decided that a) it shouldn't honor the setting of "Keep Notes & ToDo's" to "On My Mac" and b) that it knows better than the user what the path prefix should be, and c) it doesn't have a "don't ever ask me again" on that annoying dialog.
I have already filed a bug report on this issue.

Mail extremely slow, sometimes cannot connect

Mail has become incredibly slow: sometimes it take thirty seconds to load a text message with two lines.
Sometimes, upon starting up, it can't connect at all.
At the same time, the internet connection is fine, and all browsers work.
I'm on 10.8.5 with a first gen retina MacBook Pro with 512 Gb disc and 16Gb ram.
Should I reinstall Mail? What could be the reason for the sluggish performance (it doesn't happen all the time, sometimes Mail seems to work fine, but very often I get "Loading..." forever.
And, again, I'm getting the zigzag sign for interrupted connection. Why doesn't Mail work?
update: I checked activity: Mail is constantly logging out of my mail accounts, and then has to log back in, which is why it's so slow. How can I prevent Mail from logging out?
Also: Mail gets stuck in the middle of downloading messages. The blue bar in the activity window only goes halfway, and then is stuck for fifteen to thirty seconds... which is the time it needs to get me my mail.

Sometimes this problem can be cured by tidying up the Keychain, where login info is stored. You can do this by opening Keychain Access in your Utilities folder. Find the location and login info for the mail account. Delete, say, all but the most recent one. Does that fix the problem? If not, go back and delete even the recent one. When Mail asks you for your login stuff, give it, then check the box which says to store it in the keychain. Sometimes just doing this last step is enough to clear up the annoying login windows.

Processing speed of my MacBook is extremely slow when opening applications, whether Mail, Safari or MSOffice

Problem description:
The processing speed of any function is extremely slow - such as opening Mail, Safari, clicking on a page within Safari, switching to MS Word, adding a window in Safari, loading a page from Safari. I get the spinning wheel most of the time before the action is completed. All other Macs which are newer in my home WiFi network operate just fine. I have done a top level (novice) check for malware, and haven’t found anything. Any help you can suggest would be truly appreciated! Thank you!

Before you do anything do you have a current backup? If not make one.
I don't see any of the usual software suspects associated with slow downs. You don't need the Seagate software, you should uninstall that.
Reset the SMC Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support and PRAM How to Reset NVRAM on your Mac - Apple Support
You only have 2GB of ram and could upgrade to 8GB, but Snow Leopard should run ok in 2GB.....not great but ok.
Start up in Safe Mode OS X: What is Safe Boot, Safe Mode? - Apple Support be paitient as it will take awhile to start as it checks and tries to repair any problems with the file system. Once it's completely started up you can restart normally.
Insert your Snow Leopard disc and restart while holding the C key. Run Disk Utility to repair the hard drive and permissions. While in Disk Utility check the SMART status of the hard drive, anything other than Verified indicates a problem with the hard drive.
Again, you only have 2GB of ram.....try restarting your Macbook every day.....it's been running for almost a week now.

Extremely slow Safari, Mail, Firefox,etc.

I have been experiencing an extremely slow computer. Safari, Apple Mail, Firefox, Apple App store, iTunes store, any app the requires the internet. Sometimes it takes Google.com 30 seconds to load. Apple Mail routinely times out. After loading a web page and then selecting the back button, it takes over 30 seconds to reload the previous page. I have turned off iCloud.
I contacted my ISP, two service calls to check the line and they replaced the cable modem. The results from Speedtest.net were +25Mbps download so their advice was to call Apple.
I have been getting a Recoverd files folder in the trash when I start up the compter. Activity monitor only shows, activity in Finder, Firefox, and Acitvity Monitor, so nothing else is running in the background.
Any suggestions? Have I missed something?
Should I do a Clean Install?
iMac, 27 inch, 3.4 Ghz Intel Core i7, 8GB memory, Mac OS 10.8.2
Thank you.

Boot into Recovery by holding down the key combination command-R at the startup chime. Release the keys when you see a gray screen with a spinning dial.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with networks that require any kind of authentication other than a WPA or WPA2 Personal password.
From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. While in Recovery, you'll have no access to your saved bookmarks or passwords, so make a note of those before you begin, if they're needed for the test.
Test. After testing, reboot as usual and post the results.

Since upgrading to Mavericks, Mail is extremely slow to load preview pane or show email when mailbox is double-clicked. Is this a known issue?

Since upgrading to Mavericks, Mail is extremely slow to load the preview pane or show email when mailbox is double-clicked. Is this a known issue? Or is there a solution to this issue?

Hi AngieLynch,
Thanks for visiting Apple Support Communities.
It sounds like you're seeing some unexpected behavior in Mail.
Before troubleshooting on your computer, I'd strongly recommend backing up your data to an external hard drive with Time Machine, if you haven't already. This article can help with setting up Time Machine:
Mac Basics: Time Machine backs up your Mac
http://support.apple.com/kb/ht1427
Next, try creating a new user account on your computer. You can add your email account to Mail in the new user account. If Mail is more responsive in the new user account, then Mavericks is working fine and the behavior is caused by conflicts in your own Mail or user account.
These articles walk you through creating a new user and setting up Mail:
OS X Mountain Lion: Create a new user account (applies to Mavericks, too.)

Mail running extremely slow in yosemite

I upgraded to Yosemite and my mail program is running extremely slow (moving from one mailbox to another or deleting, etc.). Does anyone know of a fix?

Hi Linc,
I am using iMac [OS X Yosemite V. 10.10.2] and using Mail app for my email account via Outlook 365 office [Exchange].
Suddenly today, when I send an email, a new folder pop-up under Outbox folder named "on my mac" and the email stays in this folder for at least 15-30 minutes before it goes, and once it's being sent, my "sent folder" doesn't update the sent emails. I have repeated many test emails and run connection doctor but nothing happened!
I did the following steps, non of them worked:
1. Deleted the account and re-created it over 3 times.
2. Restarted the machine.
3. Signed out from iCloud.
4. Moved out com.apple.mail.plist folder while creating the account again.
5. Moved out com.apple.mailServiceAgent.plist folder.
6. Changed the internal & external ports to 25, 465 & 587.
7. Rebuilding.
8. Deleted Cache.db
9. Checked & unchecked "Automatically detect and maintain account settings".
10. Checked & unchecked "Use SSL".
However, I run test emails on MS Outlook app and it worked perfectly, which means that the exchange service is working.
Your help is highly appreciated.

Extremely slow address completion in Mail.app and general systems freeze

Hello all,
Since the middle of last week I suddenly experienced
a extreme slow down of Mail.app address completion,
it take about a minute to type/complete an address even
whenever the completion option is checked in the preferences.
Then Mail.app use nearly all system disk ressources: 'ls' in a terminal
takes forever to complete, safari stops responding, etc... my Mac
is unusable. I got into situation where i couldn't force-quit
or ps/kill -9 any process,... reminiscent of a PC nightmare.
In addition some mail messages are painfully slow to display,
the problem seems to occur on some specific messages and does
not go away when completion is disabled.
This happens it seems, but I am not 100% sure, after I recieved
mails with with strange accentuated charaters and ';' in some
CC addresses.
I go the zombie AddressBookSync problem described
http://discussions.apple.com/thread.jspa?messageID=8380028
starting addressbook then Mail.app as suggested by on user
solved the zombie problem, but not the completion problem
and the system is still somewhat slugish. I got a 4GB 2.4Ghz
imac. Neither my mail nor any disk item substancially increased
last week.
Now there is something strange. I tryed to remove putative
faulty addresse from previous recipient list with
'windows -> previous recipient' but the list is empty, yet
Mail.app does complete the addresses I type! (although it
does it at nerve breaking turtle speed), where are the
completed addresses taken from???
Has any one experience this problem? Any idea?
Thank

When I attempt to open Mail.app Preferences, the app freezes
