Our blackberry Z10/Q10 devices are trying to open up attachments larger then 10MB. When we try to open the attached files larger then 10MB on the blackberry devices, we get attachment too large by policy message. We can open up the message just fine in outlook and in webmail.

We have spent several hours with blackberry support on the telephone and they say it is related to active sync. Exchange active sync is not stopping the device from opening attachment of any size. Our email send/receivie email limit is set to 30MB.

Blackberry is saying it is related to exchange 2010 active sync, but I am not sure where else to look as the active synch attachment policy is setup with no entry in the attachment size field. If the defautl attachment size field in active sync is not set does it default to 10 MB?

Hi,

The Maximum attachment size (KB)   Select this check box to specify a maximum size for attachments that are downloaded to the mobile phone. After you select the check box, use the text box to enter a maximum attachment size, in KB. If this check box is selected, attachments that are larger than the specified size can't be downloaded to the device.

Probably try to set a limit of 15 or 20GB and test.

We are getting the attachment on the mobile phone/device. We cannot open it so by making this change should it allowo us to open it?

Hi bubba1984,

I have found the KB that roopal1ra0 mentioned, it is realy good information. However it related to the Outlook client, not mobile.

"We can open up the message just fine in outlook and in webmail." It seems there is no issue on the Outlook client and OWA. So the issue related to the ActiveSync.

Since the Active Sync is not supported on this current Forum, I suggest re-creating a new thread on the AcriveSync Forum so that we can get more professional suggestions.

For your convenience:

However, I can also share some information for your reference:

Maximum attachment size

500 kilobytes (KB)

More details in the following article:
