Where I work we are testing the Blackberry solution.
We use Blackberry Professional 126.96.36.199 on an Exchange2003 server, currently with one only bb user.
This user has frequently errors "Transaction error - bad format", as explained in this thread Transaction error - bad format
Generally he gets these errors while trying to download an attachment (also if I have tried a lot of times to download attachments using his blackberry without problems).
When this error happens, I try the solution from the linked thread and this solve the problem.
But I'd like to understand what can I do to have this problem much less frequently (currently it happens one time each 1-2 days).
Could someone help me? Thank you.
