Hi,
We are changing Conference call providers, and we've been asked if it's possible to identify any Outlook calendar appointments that are using the old provider. The only variable we have to search on is the call in phone number on the invite, since that will change with the new provider. They also only want the report to show Organizer. Basically what they are looking for is a report showing by Organizer, the users that haven't updated their meetings and sent out appointments with the new system. Is that possible using EWS?
Thanks for the help.
