I'm trying to run a report search from /ecp portal for some emails coming from outside of our organization to internal recepient. When I try to run Search, I get popup "Object Reference not set to an instance of an object" . So, for example we have emails coming from one of our payroll services and it would have email address of email@example.com, and it would be coming to one of our Exchange recepients. When I search for email transfers within organization, it works fine, and I can see all emails. Reason I'm doing the search is because we had the email blocked a couple of time by HUB server anti-spam filter (Content Filter i beleive), and we want to see if there were any other ones that we missed. We already added the domain to safe senders with "Set-SenderIDConfig -BypassedSenderDomains domain.com", and also by entering their SMTP servers to "IP Allow List".
Weird thing is, I can search for most other external email addresses with the Reporting, and it works (for example my own gmail account to my internal Exchange account) - it would show all emails, and I don't get this "Object Reference... " error. Only those emails that were stopped by spam filter seem to be affected (we have currently two email addresses that were blocked by smap filter, and were added to safe sender domain etc. - these are the only two I'm getting this error with).
