We have 1 user that cannot download his calendar to the company mobile phone. The e-mails download just fine. My company is using some new mobile phones (New mobile phone = Android HTC Desire) and the user did not have any problem with the previous mobile phone (Previous mobile Phone = HTC Pro 2, with windows mobile operating system). It appears that this problem is tied to this user's Exchange E-mail account.
1. If we change up the user credentials and put another user's information (username /password) in the same exact mobile phone, then the other user's e-mail & calendar does download correctly.
2. Equally important, if we take the 'rouge user's credentials to another mobile phone, that we know is working well for another user, the same problem follows the 'rouge user'.
... Again, the problem is that the calendar will not download. The 'rouge user's e-mails do download just fine. The same user has had no problems accessing the cached calendar information from his client computer. Or accessing the calendar from the OWA.
My question is why would the calendar not be downloading for this 1 user on these phones?
HTC Pro 2 was the previous Windows mobile phone that worked. The rouge-user has synchronization screen that has a server folder. That server folder contains 18,000 items. Another user that works has only 4,000 items. Could that be the problem? is this 'rouge user's exchange account too large?
