Size limit for sending attachments?

Anyone know what the size limit is for sending/forwarding e-mails with attachments when using a BES?


I am the IT administrator and all the file sizes are set to unlimited in the BES attachment manager configuration.

A user received an email with a 4MB attachment and they are attempting to forward it and they are unable to.


In researching this some people have said this is a RIM limitation, I haven't found any definitive answer from an official source on this though.


I did find this FAQ:


That says it's either 4MB or 2MB.

But i'm not sure if they're only taking about POP or BIS accounts and not a corporate server in the mix or not.


Any info would be appreciated.

During a brief search of the Blackberry support page I found THIS.  It shows in an Enterprise Environment the limitation is at 3MB.


However, I only did a brief search so I'm sure if you do more digging at you can find more information.


Good luck.

Re: Size limit for sending attachments?

Thank you very much.


it is 3MB.


this is also described here:



This is really surprising to me.

RIM needs to upgrade their network from  late 90's standards.

It's pretty common for people to send and receive attachments larger than 3MB these days.



I will need to start recommending people buy android, windows mobile or iphones moving forward.
