1. Narrow the scope of the problem

1. How many users are affected

two。 Whether all affected users access exchange using the same method

3. What do users want to do?

4. Is it normal for other users to perform the same task?

5. Are all users in one database?

6. Are they all on the same site?

7. When does it occur and how often the failure occurs

Second, use basic troubleshooting tools

1. No matter what happens, check the event Viewer first.

two。 Use the TEST command

{for example: 1. Get test command: help test-*

All commands at the beginning of test

2.get-servercomponentstate gets the server component status 3.test-servicehealth to view the service running status. This command automatically filters the service based on the CAS or MAILBOX server. 4.test-mapiconnectivity tests two key protocols that clients use when connecting to priority servers: MAPI\ LDAP. And indirectly confirm whether the MAPI server, exchange storage, and directory service access DSaccess is working. 5.test-replicationhealth checks the running status of the replication service and prompts you for errors found. After 6.Get-MailboxDatabaseCopyStatus verifies the replication service (the fifth command), you can use Get-MailboxDatabaseCopyStatus to check the replication status of the database itself.

Get-mailboxdatabasecopystatus | fl name,status,contentindexstate

Contentindexstate is the index state, which ensures that the healthy state is maintained.

7. Mail flow test test-mailflow tests the submission, transmission, and delivery of mail. Verify that the server can successfully send mail to itself. It can be followed by the parameter targetmailboxserver\ targetdatabase\ targetemailaddress. If DAG is deployed, use the targetdatabase parameter directly}

Third, solve the problem of mailbox server

1. Is the database replication running normally?

two。 Whether the performance of the server is limited

3. Is email delivery normal?

4. Ensure that all services are running properly

5. Whether there are any errors related to msexchangedatbase, msexchnangedatabase instance, msexchangesubmission in the log.

6. Is there an active Directory problem?

7. Use the TEST-MAPICONNECTIVITY command to test

This command does not test the exchange storage service, but also tests AD access, RPCoverhttp access.

8. Whether it is quarantined (poison mailbox)

Poison mailbox concept: by default, the Mailbox server marks any mailbox that causes threads in the store.exe service to crash or connect to five or more "suspended" threads. If a mailbox is marked three times within two hours, Exchange Server 2013 will block access to the mailbox for up to six hours or until the administrator unblocks it, whichever comes first. If the user reports that she cannot connect to the mailbox, but other users do not experience any problems, check that there is a quarantined mailbox on the server.

Command used: get-mailboxstatistics | fl isquarantined

It is quarantined if the isquarantined parameter is $true.

9.TEST-REPLICATIONHEALTH

Check the running status of the replication service and prompt for problems found

Fourth, solve the problem of mail transmission

1. The focus of solving the problem of mail transmission

1.1 whether all emails can be sent or limited to some users

1.2 whether you have received the rejected letter and whether there is a code

1.3 whether it is in a unified organization

1.4 message delivery distance

1.5 message path between sender and recipient

two。 Consider whether the following problems exist

2.1 DNS failed to find A record

2.2 site link error there is no site link between sender and recipient

2.3 whether the transmission limit mailbox is full

2.4 Transport rules

2.5 messages stranded in message queues

2.6 reverse pressure occurs on the server (refer to blog posts for the concept of reverse pressure)

3.TEST-MAILFLOW 4. Queue Viewer, 5. Message tracking 5.1 Autonomous message tracking report OWA- option-delivery report (tracking your own messages only) 5.2 EXCHANGE Central Administration message tracking EAC- mail flow-delivery report (total all user messages) 5.3 GET-MESSAGETRACKINGLOG
