I have migrated my boss email account from Exchange Server 2007 to Exchange Server 2010 just now. After migration, he removed his mail account from Mac Mail (Mountain Lion) and created it using new Exchange Server 2010 user setting. All sub-folders under Inbox can sync into his iPAD and iPhone. Email can work normally. However, all sub-folders under Inbox cannot sync into Mac Mail. All sub-folders under Inbox was empty. However, he can send and receive use his Mac Mail. He tried to rebuild in MAc Mail. prolem still exist.
His mailbox size is arounf 4GB, Inbox size (not include sub-folders) is around 2GB.
I tried to open his mailbox using Outlook. Everything worked fine. Our Exchange Server locate on Hong Kong and He is in Canada now.
I want to know the sync order in Mac Mail. Does Mac sync all message in inbox folder first and than sync inbox's sub-folders?
