We are using exchange 2013. Now I have assign the full mailbox permission to User A for original mailbox User B.
Now when I opened outlook , its appearing in my outlook but When I am sending an email from User B , its getting fail with the following warning..
This message could not be sent. Try sending the message again later, or contact your network administrator. Error is [0x80070005-00000000-00000000].
I search from this link and disable the cache mode but still facing the same issue..
I have assign the send as and full mailbox permission both , and it works fine…but if i assign only full mailbox permission its not working…
My outlook 2013 is version 15.0.4420.1017
What could be the reason..as if full mailbox permission should work properly..
