I have set up site mailboxes on my farm, with no errors on the scripts.

Adding the site mailbox app onto a site yields the following error:

Could not contact the SharePoint Server

The ULS log has the following information in it:

System.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.b__e() StackTrace: at Microsoft.Office.Server.Native.dll: (sig=678c0f87-966f-4d99-9c94-b49e788d2672|2|microsoft.office.server.native.pdb, offset=131CE) at Microsoft.Office.Server.Native.dll: (offset=21BE5)

I've tried redoing all the set up steps, have installed the latest exchange web services api...I don't know what else to do to fix this.

Any help on figuring out why this is happening would be very appreciated!

  • Thanks @WaqasSarwarMCSE, It might actually be that, I'm looking into it now – Mahendran Govender Apr 2 '15 at 9:28
  • Hi @WaqasSarwarMCSE, the error remains after the entire sharepoint farm was reverted to its original certificate. I checked the trustedIssuers, and there are two that do not have NameId's... Must all Issuers have NameIDs for Site Mailboxes to work? – Mahendran Govender Apr 7 '15 at 8:48
  • are you using all ? – Waqas Sarwar MVP Apr 13 '15 at 19:46
  • Yes, the other issuers are being used by other features, so removing them is not a viable option – Mahendran Govender Apr 14 '15 at 11:25

  • Hi Chad, We are using domain issued certificates, so the certificates should be fine...thanks very much for the article though, it covers the pre-requisites very nicely! – Mahendran Govender Apr 15 '15 at 9:10
