Out of office does not work in cached exchange mode

When I turn on Out of Office with Outlook for clients that are using cached exchange mode it turns on but does not actually work. If I turn off cached exchange mode or turn on Out of Office through outlook web access it works fine.  This is troublesome because most users I have are in cached mode and won't know oof is not going to work when they turn it on via outlook 2007.

This is a 2003 AD, with one exchange 2007 server and all outlook 2007 clients.

Hi There,

Does Autodiscover work in your scenario??

OOF relys on Autodiscover, make sure that Autodiscover works fine to make OOF working.

Check with Autodiscover Whitepaper at the below link

+ Are there any errors in App Logs with regards to MSExchange Availability or System Attendant Mailbox?
+ Are you able to see F/B information of users present in the domain?
+ What is current SP level and rollup installed on Exchange?

+ Incase if you are getting any errors of warnings in Application Logs, I would like to have a look at it.


There are no errors for either service in the apps logs.  Yes I can see free busy for everyone.  Note that everything works fine except out of office in cached exchange mode.

Running SP1, rollup 8.
Hello dmwynne,
When you say it doesn't work, does that mean that OOF message aren't replied back or is it something else?
Also when you try to set OOF on Outlook which is on cache Exchange mode, does that change reflect in you OWA.


Messages aren't replied back.

The change does reflect in OWA.
