My team and I are in the process of integrating our custom CRM (fully built on the MS stack) with Exchange. A key part of this integration is linking Exchange positions (namely meetings and tasks) to customer records. Basically, when a salesperson schedules a meeting with a specific customer, the customer’s GUID joins this meeting as a custom extended property . Simple enough, right?
When we are dealing with a single mailbox, looking for a custom extended property is easy. But what about multiple mailboxes, for example, to search for all meeting sales calendars with a specific client GUID as a custom extended property?
Can I search all (or several) mailboxes for a given custom extended property? Is binding our data using custom advanced properties even the right method?
Wednesday We use the EWS Managed API to talk to the Exchange 2010 server. Exchange 2007 EWS and aut-gen proxies work the same way, however, therefore, the proposals for 2007 should be applicable.
