How to set number of emails/size that reside in inbox?

[JMSLANDON]

Good Morning,

I have a guy that is using the HTC Touch pro. I have a rule set in outlook sto forward copies of his voicemails to his "inbox" as a email with a media attachment. This is working fine in outlook as the email copied from the cisco unity server to his inbox. For some reason he does not receive all of these emails on his HTC. I noticed that he is receiving other emails without a problem but 50% of the time these emails with attachments dont come through. Is there some kind of a size limit set for emails that can be synced??? If so, where can I change this setting. Also, he is telling me that his inbox on the touch pro will only store 26 emails at a time? Is there a setting that can be changed for this?

Thanks for any help or ideas you have!
