Hi,
recently I've had to reimport some appointments in Outlook2010 in a Exchange 2010 environment. Unfortunately I read that post too late https://support.microsoft.com/en-us/kb/2167170
The post says the GOUID changes and that why the user don't have the "send upate" button. I took a look with MFCAPI, But the ID in the properties 0x03 and 0x023 are the same as in the appointment from the users which were invited.
So, is there any way, that I can recreate manually the "send update" button ?
Greetings,
Bjrn
