Rcently upgraded from a curve 8900 to a bold 9900. Great upgrade, only problem is that from my university e-mail account I am receiving approximately half of the e-mails from my university e-mail on my blackberry device.
Although my university states that their e-mail client is not supported by blackberry, although I never had a problem with my old curve, and it never struggled with the setup.
My hotmail account is working just fine, which implies it is a specific problem to my university e-mail address, (but it is not specific enough to stop all the e-mails coming through!).
Vodafone stated that hotmail is working, then it is not their problem - being as obviously the general systems are up and running.
So far I have:
o hard reboot
o re-sent service books
o deleted and re-installed university e-mail
o re-registered with my carrier
