I have now tested some things to solve this problem, and I suddenly only had the problem with one single user. Application log was filled up every 15 secoonds with Event ID 8230, 8206, 8213 and 8199 I read this blog about "Troubleshooting Exchange 2007 Store Log/Database growth issues" and come over some ideas. Tried to disable the MAPI and Activesync MAPI 1. Set-CASMailbox -identity 'username' -MAPIEnabled $false 2. Moved the mailbox to another store to stop all active MAPI sessions. Checked the application log on the mailbox server for new events and after som minutes the events started poping up ActiveSync 1. Set-CASMailbox -identity 'username' -ActiveSyncEnabled $false Checked the application log on the mailbox server new events, and after 2 minutes, the EXCDO events for this user stopped. The HTC S740 that the user is using will be wiped and setup again to try solve the problem. /Joachim Løe Joachim Le | Crayon AS | MCITP: Enterprise Messaging Administrator 2010
