|Title||msexch_database: Fixed disappearance of services caused by dynamically generated IDs|
|Checkmk Edition||Checkmk Raw Edition (CRE)|
|Compatibility||Incompatible - Manual interaction might be required|
After a reboot of the exchange server the databases get dynamically generated IDs. These IDs were part of the items which led to vanished services. This has been fixed now. You have to perform a re-discovery on the affected hosts.
