I have now noticed that in the log file "BigFunnelRetryFeederTimeBasedAssistant" there have been constant entries with the error "Microsoft.Exchange.Data.Storage.AccessDeniedException" since the update. Can someone tell me what I have to do so that access is possible again and so that the indexing will hopefully work again?
