The Active Directory schema isn’t up-to-date, and this user account isn’t a member of the ‘Schema Admins’ and/or ‘Enterprise Admins’ groups.
I am busy installing Exchange 2016 in a test environment and received the below error when running Setup.exe /IAcceptExchangeServerLicenseTerms_DiagnosticDataON /PrepareSchema when trying to extend the domain schema. “The Active Directory schema isn’t up-to-date, and this user account isn’t a member of the ‘Schema Admins’ and/or ‘Enterprise Admins’ groups.” Thing is, my account is part of the Schema Admins and Enterprise Admins group. I then found the solution from this post (thanks Andy!) In short, open the group membership tab on your account in Active Directory Users and Computers and then check which group is set to default, then click on Schema Admins and click on Set Primary Group to make…

Error: MigrationRecipientNotFoundException: A recipient was not found for “mailboxName”
If you received the error “Error: MigrationRecipientNotFoundException: A recipient was not found for “mailboxName”” when migrating a mailbox to Exchange Online (Office 365) then check for the below AD attributes. The error from the Exchange Admin Portal on Office 365: Open the on premises Exchange Management Console and search for the user. You should see the mailbox shows it’s a Linked Mailbox instead of a Remote Mailbox as expected: To rectify this, open AD Attribute Editor and browse to the msExchRecipientTypeDetails attribute. You should see the below: Change the Value of 2 to 1 for msExchRecipientTypeDetails as you need the mailbox to show as a user mailbox on premises before…

VB.Net application unable to connect to some Exchange 2010 mailboxes
We had an interesting issue last week where a Visual Basic .Net application could connect to some mailboxes but could not connect to other mailboxes on Exchange 2010. The application uses MAPI to connect to the mailboxes. We were however able to access the affected mailboxes using Outlook and with the MFCMAPI tool from the application server. We moved the affected mailboxes to other servers and databases but the application could still not connect to the affected mailboxes. We then added our CAS Array name and IP in the application server’s host file and checked the Exchange RCA logs. We could not see any connections from the application server to…

Find a duplicate e-mail address in Active Directory
We recently started seeing a lot of mails stuck in the submission queues and found that there were a few duplicate e-mail addresses in the environment. Most of the time we could not find the duplicate addresses in Exchange and had to search for the duplicates in Active Directory as some addresses were bound to AD objects. To search for a duplicate address do the following: Open Active Directory Users and Computers Right click on your domain name and click on find Next to find choose custom search (see below screen shot) Then click on the Advanced tab (see below screen shot) Under “Enter LDAP query:” type the next search…

Unable to see remote mailbox on the on premises Exchange servers but can see it in Exchange Online
We’ve had a few instances where a user could not receive mail into their Exchange Online mailbox.

Exchange 2003 Services won’t start – Event ID’s 9175, 2114 and 1005
Exchange Server 2003 services does not want to start or takes a long time to start for all the Exchange servers in the same site. We had this issue and found that the Exchange servers tried to authenticate with a domain controller in another site. I found that the Exchange servers had the local Domain Controllers configured in Exchange and could contact the servers using ping and telnet. The application log showed 3 errors that were related to the Exchange Servers not being able to authenticate to the local Domain Controllers. The event ID’s were 9175, 2114 and 1005. Solution: Add the “Manage auditing and security log” permission under “local…

E-mail address strikethrough in Exchange 2007
We had a problem when our provisioning system would not update the “managed by” property for a distribution list. Further investigation showed that the distribution list’s e-mail address had a strike through like this: (Seen in the DL’s properties using EMC) email@company.com We could not add a new smtp address to the group nor delete the current address. We then opened ADSIedit to have a more in depth look. We then noticed that the SMTP address in proxyAddresses had a space before the @ in the SMTP address. We rectified that and the strikethrough disapeared. We made the changes and managed to provision the DL without any problems.
