Microsoft Exchange IS Client Type - Keeps flapping since a few days ago

[MarcS]

Did you also re-roll out the agent after you adjusted the timeout?

Otherwise you can also adjust it manually on the Exchange server in the agent as a test:

Exchange check failed - please submit a crash report!

Hello Kevin, we also had this problem after updating our Server to 2.3.0p11. This only occurred for Excahnge Services. I solved this by increasing the wmi timeout on the Exchange Server (not cmk Server): In C:\Program Files (x86)\checkmk\service edit the File “check_mk.yml” increase the line wmi_timeout: 5 from 5 to 8 (seconds) Maybe you have to increase it more on your systems. You can also set the timeout by rule and roll out the agent again: Setup > Agents > Windows, Linux, Solaris, …

Kind regards, Marc
