Hi We received the same error today, where users inside the organization connecting to exchange server using outlook Mapi connection experienced a slight delay in sending\receing emails. Where outside users, faced lot of delay in sending and receiving email. Performed a test on all the exchange related parameted, like service health, Mapi connectivity test and database health. No issues found. Network team didnt find any issue related to this finally we rebooted the server and all is fine now. and the above event is not apearing. :)
