iPad Mail - Maximum Attachment Size Limit (Sending)

Is there a maximum size limit for attachments that the iPad Mail App can send?

We have an iPad connected to an Exchange server through our internal wireless network. Mail is received by it (even with very large attachments) but if an email is sent with one or more attachments that total over 10MB, the email stays in outbox with an error "Cannot Send Mail" "An error occurred while delivering this message."

I've checked all of the limits on the Exchange server but these are all set to 20MB. Smaller attachments (6MB, 8MB, etc) work without any issues. I've searched these forums and around the internet but haven't been able to find anything about this and nothing about where any such limit would be configured.

Thanks in advance for any help

Hi Barry and welcome to the Apple Discussions.

There very well may be an attachment size limit for the iPad Mail app. This article discusses the limits for the Mac OS X Mail program so one could reasonably expect a limit for the iOS app also.

Hi Ralph,

Thanks for the response. I followed the link you posted and it does seem likely that there's a similar limit on the iPad. I'll have to see if I can find a way around it now.

Gmail allows a max of 25MB for an mail attachment. I just sent a 22MB email attachment from the iPad with no problems.

Hmm, curious. After your post we went back tried everything again just in case something was missed - same thing happened. One of my colleagues then set up his personal mail account on the iPad and this then worked so it seems as though our Exchange server may have an attachment size limit hidden away somewhere. If we get to the bottom of this then I'll post the fix back here.

Hi Barry,

When I was searching the Apple Support data base, upper left corner next to Support, for mail attachment limits it returned a series of articles on Exchange limits. You might want to do that search on the data base and see if anything in there is helpful to you.

Done it! My colleague found an article here: http://www.i-tekpro.com/BlogArchive/Exchange2007/Max-Message-Size-Increase-Excha nge-2007-CAS.htm that discussed how to change a limit in an Exchange ActiveSync config file that seems to have been tripping us up. We changed the limit and got the email through. It's worth noting that this also applies to Exchange 2010, not just 2007.

Many thanks for your help with this,
Barry

Great, doesn't matter where the source of the problem is as long as it can be resolved.

Enjoy the iPad.

Has anybody faced the same issue on Exchange 2003? Or does anyone know how to change the limit in Exchange 2003's ActiveSync config? I can seem to open a 2.7MB file, but not an 11.2MB file.

Tried searching on Google to no avail.

Hi Cardula!

I have the same problem with exchange 2003. Sending Mails with small attachments (100 KB) work. Larger (1000KB) don't.

Did you find a solution?
