When sending letters more than 8Mb - an error occurs, "Sending failed, the mailbox is full."

[Arturxr]

Faced the following issues while using the Mobile Access Blade (cp4400 r77.30):
When sending letters more than 8Mb - an error occurs, "Sending failed, the mailbox is full."
sk133952 - did not solve the problem.

Sounds like an Exchange issue - or does sending work without MAB ?

[Arturxr]

sending works with MAB

[G_W_Albrecht]

So what is your issue if sending works ? That is confusing...

[Arturxr]

initially I didn’t quite understand the question, we have MAB, but letters with attachments larger than 8mb are not sent

[G_W_Albrecht]

Does your exchange server send letters with attachments larger than 8mb without MAB involved ?

[Arturxr]

 how can we test this? 

[G_W_Albrecht]

Ask you Admin - our exchange also has 6MB limit...

Are you atleast running the latest JHF on the gateway?

R77.30 version and 4400 hardware are both beyond their end of support milestones at this point and upgrades are necessary.

Chris is 100% right, both 4000 appliance and R77.30 are out of support. Having said that, if you tried the sk mentioned, would you mind sending us a screenshot of the Guidbedit value changes, so we can at least verify its corretc?
