When I send an email with an attachment larger than 1 MB in iMail, the email takes forever to be sent.

When I send an email with an attachment larger than 1 MB from iMail, the email gets suck in the sent folder.  This happens no matter if I am using wireless or using an ethernet connection. 

Many email programs, including Mail, will send data up to a certain size.
The good new - there are some solutions. You can compress the file and make the email much faster to send; you can download a free application like Compress, which also allows you to uncompress. Or, you can send your email via your webmail connection (your ISP, like ATT); if you manage your email through your desktop computer, the email should be sent just fine.
Apple Mail is designed for smaller documents, well under 1mb.

  • How do I send an email with an attachment larger than 20mb

    I am using exchange 2013 and I have users that when they send any emails with attachments over 20mb, it fails.
    How do I change the setting to allow up to 30mb attachments in size?  I've googled this, but to no avail.
    In ECP, I looked under mailflow and then rules, but I don't have any rules there. I tried creating one, but I can't because I don't have the enterprise CALs I guess is what it's telling me.
    Any help would be appreciated.

    Hello Everyone, I've already tried everything that was suggested, I changed everything to 50 or 60 MB.
    The user settings is unlimited.  For testing, I changed my own account to 100mb.
    Still the same error message.

  • I keep getting "undelivered mail returned to sender" that comes with an attachment. I have not opened the attachment but the email returned is usually from people that i have not emailed in a long time.

    I keep getting "undelivered mail returned to sender" that comes with an attachment. i do not open the attachment but i get email returned from people that i have not emailed in years. I also have current people that tell me they receive email from me and there is nothing on the email and it is a repetative thing for them and for me. I have scanned my computer and it keeps telling me there are no viruses but i keep getting these emails. can anyone help me please!

    Someone is probably sending spam with your address forged on the To: line.  Could be one of your old contacts with a Windows machine has a virus that's doing it.  It's also possible your e-mail account has been hacked, though I'd think such a hacker would be a bit more purposeful.

  • When I receive an email with an attachment I am unable to read the attachment. I contact AT&T and they say the problem is with Firefox.

    when I receive an email with an attachment and download it I get a message stating that the attachment can not be read for various reasons. My provider has tried to help but unable, they stated it is the problem with Firefox. I have updated Adobe reader several times with no luck. All of my working friends are able to download and read the same attachments but not me. I am the only one with Firefox, so I can say it is Firefox that causing the problem. HELP

  • After creating an apple ID it says it has to verify my email adress and will send an email with a verification link. I never get the email.

    I created an iapple id and it said it had to send me a verification email to verify my email adress. It said ....email sent please click on link. I did this several times and although it says email sent...i never get the email.

    Apple ID security issues -
    Account security issues almost always require you to speak directly to an Apple representative to securely establish your identity as the account holder. You can set it up so that Apple calls you, either immediately or at a time convenient to you.
    1. Go to https://getsupport.apple.com/Issues.do
    2. Choose Other Apple ID Topics and choose the appropriate topic for your issue
    4. Follow the onscreen instructions

  • When I have an email with an attachment, I can now only "save" the attachment. How can I open before I decide if I want to save?

    I used to have an option to "open" attachments as well as "save" them. This ability has disappeared and I am unable to just "open" an attachment, or a form, for that matter, on a website. I can only "save". I have no idea why I can no longer "open" anything. How do I get this option again? I have tried settings for Mozilla and I don't see it there.
    Very sad, am I.

    It is not a webpage that I have trouble with, it is attachments to emails; both text and photos.

  • Whenever i try email with iPhoto i get message pop-up saying the sever didn't recognise your username/password combination.

    Whenever i try to email with iphoto i get a pop-up saying THE EMAIL SERVER DIDNT RECOGNISE USERNAME/PASSWORD COMBINATION

    Are you sending from your iCloud Mail address? And do you have two-step verification enabled?
    If you had two-step verification enabled, you have to set up an app-specific password for iPhoto, if you want to use iPhoto as a Mail client.
    See the post below:
    Re: I am using iPhoto version 9.6 and I can no longer get an email sent with a photo attached. I get an error message saying the email did not go through because the server did not reply. I can send the photo with Mail. Help!in response to Gary Kissler | This solved my question
    This solution is for those of you using 2-step verification for your Apple ID and are using iCloud as the mail server that you are trying to mail photos with.
    I too had this issue. The problem in my case occurred because I had setup 2-step authentication for my Apple ID. If you have done this then you will get the error message "the mail server did not recognize your email/password...". To solve the problem go to:
    https://appleid.apple.com
    Click "Manage Your Apple ID"
    Verify your identity with the device you selected (if this step does not show up then you have not likely set up 2-step authentication and this is not your solution)
    Click Password and Security in the left column
    Click Generate an app-specific password
    Enter iPhoto as the name of the app
    Copy the password and paste this into the password box in iPhoto where you would normally enter your apple ID (in the mail account section in iPhoto preferences).
    And...voila' (I hope)

    I have Windows 7, Microsoft Outlook and PSE 13. I have used the "Share photos as embedded images" feature frequently, but today when I went to use it, it wasn't there, only the option to send email with files attached. How do I get back the ability to send emails with photos embedded. I like adding the frames and backgrounds and I think it's easier for recipients to look at the photos. Thanks for any suggestions of things to try.

    I had a similar problem in that my wife's iphone 5 could not send pics with imessage.  Had to set the settings to default to SMS or whatever.  After laboring many hours on the web I coincidentally was on the phone with the internet people to question my internet speed.  They changed the router channel, which is something that I am capable of doing myself.  After that, the pics go over imessage.  My own Iphone didn't have the problem.  We are both latest IOS 7.0.6.

  • When I try to send an email with photo attachment to a contact a screen appears stating "the sender name is not recognized by the server " what do I need to change so this will not happen in the future. I am a novice!!!!!

    When I try to send an email with photo attachment on my iPad a screen appears which states " the sender is not recognized by the server" . What do I have to change so I can always send emails fr om my iPad with or without attachments. I am a novice!!!!!!

    If you purchased about 2 years ago new I am sure it is a Intel iMac. To find out what type of iMac you have just click on the Apple menu item in the finder and select about this Mac. I would check the ISP mail site and get the correct outgoing mail server info.

    Can you open to pic say in Preview, select All, Copy, 7 Paste into Mail?

Same code was worked in 4.6B.But it is not working in ECC version.When i try to open the attachment, i get a Dialog Box with the following message
    "The file is not in a recognizable format.
    1. if you know the file is from another program whih is incompatible with Microsoft excel,click cancel,then open this file in its original application
    2.If you suspect the file is damaged, click help for more information about solving theproblem.
    3.if you still want to see what text is contained in the file, click OK.Then click the text import wizard. "
    when i click OK, the excel sheet is opening with all required data.
    Can anyone kindly tell me why this is happening.
    I am also attaching part of the coding related to this requirement.

  • I am unable to send an email with an attachment I created in Pages.I have installed version 5.0.1

    I am unable to send an email with an attachment I created in Pages version 5.0.1. It also prevented me from sending out any other emails with or without  an attachment. I finally fixed my email so I could send out again but when I tried to send an attachment created in Pages it wouldn't allow it.  Can someone help me, please! Thanks!

    Pages 5 is having problems with GMail, Google and Yahoo. Dropbox may have fixed their problem with an update.
    Along with this problem and others, Apple has removed over 90 features from Pages 5.

    Pages '09 should still be in your Applications/iWork folder.
    Archive/trash Pages 5 and rate/review it in the App Store, then get back to work.

  • On my mac why does it take so long to send a Email with an attachment, on my mac why does it take so lone to send a Email with an attachment

    on my mac why does it take so long to send a Email with an attachment, on my mac why does it take so lone to send a Email with an attachment

    It depends on the size of the attachment and the speed of your internet connection.
    Next time you send an email with an attachment do these two things:
    In Apple Mail (I assume you are using Apple Mail), under the Window menu select Activity. Arrange the Activity window so you can see it.
    Then open the separate application located in the Utilities folder called "Activity Monitor" and arrange it so you can see it at the same time as the Activity window in Mail.
    In Activity Monitor program, select the tab labeled "Network." Watch the "Data sent/sec" portion. Then send your email, while watching the Mail Activity window and also the Activity Monitor program window Data sent/sec area.
    You should see the mail being sent with a progress bar in the Mail Activity window and also you should be able to see how many bytes/sec or KB/sec or MB/sec your internet connection is giving you in the Activity Monitor window.
    Example: my internet provider gives me about 20 Megabits per second download and 5 Megabits per second upload. To convert these to Megabytes per second (Activity Monitor shows things in bytes, not bits), simply divide by 10 (not the exact thing to do, but close enough). So I get 0.5 Megabytes per second upload speed. When I send a file that is 5 Megabytes in size, it takes about 10 seconds if I am getting the full upload bandwidth. If I am getting less than that (which sometimes happens), it will take proportionately more time. Either way, you can see what is happening with these two windows.
    If your internet provider is supposed to give you, say, 5 Megabits/sec upload (0.5 Megabytes/sec), but you see only say, 5 KB/sec (=0.005 Megabytes/sec), sent in Activity Monitor, then your emails are taking a long time because you are getting only abut 1/100 the speed you should be. You might want to check with your internet provider about that.
