Thanks for your reply snagrat.
Using the RPC/HTTP connectivity test, everything appears to pass fine until the very last routine which produces this error:
Attempting to ping RPC endpoint 6001 (Exchange Information Store) on server smtpin.lancsngfl.ac.uk.
The attempt to ping the endpoint failed.
Additional Details
The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process.
Elapsed Time: 3163 ms.
From what I've read so far, it's probably a firewall or Outlook Anywhere issue. But as it's a hosted exchange I won't be able to troubleshoot.
OCL have told me that other schools are migrating over to Office 365, so I'm hoping it is possible.
Anything else I can try?
Thanks
