Hi I have problems with Exchange 2003 Server Active Sync. Some users have iPHONE4 and some blackberries but almost all of them are experiencing problems with calendar syncing on their phones. Two errors I am getting. Event ID 3005 HTTP 500 and also event id 8206 where it says calendaring agent failed with error code 0x80040219 while saving apoointment. Also recently i get error like event ID 8199 calendaring agent failed in message save notification with error. Exchange 2003 is with Service pack 2. Hope someone experienced something like this and has some solution Some people advised that I should create new data store and move affected mailboxes to another store before actually trying to run eseutil and iisinteg utilities ThanksDalibor Bosic

Hi According to your event error id, it seems to be database corruption. People’s suggestion is correct. You can move mailbox to a different store or Run Isinteg on the affected database .
