Howdy,
I'm reading through configuration document (http://technet.microsoft.com/en-us/library/jj552524.aspx) and there's some inconsistencies with the version number of the EWS that's supposed to be installed on the WFE. The document states that the version has to be 15.0.516.25 or above but the download link points to a version of EWS that's 15.00.0516. In fact I can't seem to find version 15.0.516.. considering the numbers are so similar, it may have been a typo.
Can anyone confirm this?
The reason why I'm asking is because I cannot get SharePoint to create a Site Mailbox. Looking at the ULS logs I found a null object reference:
w3wp.exe (0x1638)0x11D4SharePoint Portal ServerSite Mailboxajv81ExceptionSystem.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.SharePoint.Portal.CollaborationMailboxInternalService.ExchangeHasPermissionsToSiteSubscriptionInternal(SPWeb web, CollaborationMailboxErrorCodes& errorCode) at Microsoft.SharePoint.Portal.CollaborationMailboxInternalService.<>c__DisplayClassf.<ExchangeHasPermissionsToSiteSubscription>b__e() StackTrace: (null43a7ab9c-5e7f-9035-ca67-3e0abcd84b10
