- It is disabled on the client (you can double check on OWA)
- You have started outlook with the /cleanrules switch
The following has just worked for me (you could try without running /cleanrules if that will delete many rules)
- go to http://mfcmapi.codeplex.com/ and download the app
- Close Outlook
- Session > Logon >
(select mailbox)
- Select user mailbox from the
options
- Look for ‘PR_OOF_STATE’
which should be (incorrectly) set to ‘True’
- (double-click the value and
untick the ‘Boolean’ option)
- Close the MFCMAPI application;
you can re-open to test, but it should write the change immediately
