Database availability group must have quorum error

Database availability group must have quorum error

Decommissioning set of old Exchange 2013 servers had to export few mailboxes and
decommission them.But mailboxes are not mounting saying quorum not found. but for me the simplest way is to remove the Database Availability group completely and mount the databases and take the required data out via pst and decommission the same. So this might not be suitable for all scenarios.


Failed to mount database "MDB03". Error: An Active Manager operation failed. Error: An Active Manager operation
encountered an error. To perform this operation, the server must be a member of a database availability group, and the
database availability group must have quorum. Error: Unable to read from the cluster database. This may occur if the
server has recently been removed from the database availability group. [Server: MBEX01.azure365pro.com]
+ CategoryInfo : InvalidOperation: (MDB03:ADObjectId) [Mount-Database], InvalidOperationException
+ FullyQualifiedErrorId : [Server=MBEX02,RequestId=c41e871c-49e5-4a78-877f-51738b965ee1,TimeStamp=6/2/2020
6:11:51 AM] [FailureCategory=Cmdlet-InvalidOperationException] 7E29F70A,Microsoft.Exchange.Management.SystemConfig
urationTasks.MountDatabase
+ PSComputerName : mbex02.azure365pro.com

Removed all the Database Copies.

Using the configuration only switch and removed the mailbox servers from the DAG.
So that it will clear the DAG related entries from active directory.But this will not remove the dag member from real Cluster. Which we have to manually.

Remove-DatabaseAvailabilityGroupServer -ConfigurationOnly -MailboxServer SRV-HO-MBEX02 -Identity DAG2

As its a IP Less DAG,We cannot use the cluster manager to evice them. You got to use powershell.
To Evict the DAG Members.

Get-ClusterNode Node1 | Remove-ClusterNode -Force
Get-ClusterNode Node2 | Remove-ClusterNode -Force

Once the DAG Members are removed and it doesn’t have configuration on active directory. Now the databases will try to mount as a stand alone server.On reboot Databases mounted without DAG membership.

Now removed the DAG. using below commands. I have done the same steps when the cluster is completely messed up and none of the recovery options worked and we had to bring up the databases stand alone without DAG membership. Unless you understand the environment completely and don’t use this procedure without proper understanding of clusters and DAG attributes stored on Active Directory. It may cause real Damage to the environment.

Rename Office 365 Unified Groups

Renaming Office 365 Unified Groups and updating group email address or domain is not via GUI at this point of time. we need to use powershell to update the same.

Connect-EXOPSSession

 

Run below to get the required groupID

Get-UnifiedGroup

Once you get the required group ID , Use below to check the email address

Get-UnifiedGroup -Identity "InformationTechnology_50e33be9-0000-43e4-8dc4-000044ab1a4" | FL EmailAddresses

Run the below command to add SMTP alias which will be the primary address or you can leave it as alias whichever is your requirement.

Office 365 Mailbox not showing in Hybrid Exchange server

Newly created Mailbox not showing in Hybrid Exchange Server Control Panel.Not all administrators certainly know that they should not provision office 365 mailbox directly from the office 365 console. They should have used the Hybrid server to provision new cloud mailboxes.

User Created Directly on Active Directory and created a mailbox on Office 365 without using the hybrid server. Creating an issue on some mailboxes not visible in hybrid server

Below Commands will enable you to get the mailbox under Get-RemoteMailbox in Hybrid Exchange server.

Run on Azure AD Connect Server or Hybrid Exchange server with Active Directory Tools installed.

Please replace  domain / domain.com on 3 rd and 4th line with your appropriate domain names. You can get these info from a working mailbox.

$uid = read-host "Please enter username"
$mailnick = read-host "Please enter same username"
$tempmail = $uid+"@domain.mail.onmicrosoft.com"
$primarymail = $mailnick+"@domain.com"
Set-ADUser $uid -Clear homemdb, homemta, msExchHomeServerName, msExchPoliciesExcluded
Set-ADUser $uid -Add @{msExchRemoteRecipientType="4"}
Set-ADUser $uid -Add @{mailNickname="$mailnick"}
Set-ADUser $uid -Add @{msExchProvisioningFlags="0"}

Set-ADUser $uid -Add @{msExchModerationFlags="6"}
Set-ADUser $uid -Add @{msExchAddressBookFlags="1"}
Set-ADUser $uid -Replace @{targetaddress="$tempmail"}
Set-ADUser $uid -Replace @{msExchRecipientDisplayType="-2147483642"}
Set-ADUser $uid -Replace @{msExchRecipientTypeDetails="2147483648"}
Set-RemoteMailbox $uid -PrimarySMTPAddress $primarymail

This value you need to add from a working mailbox as the number differs with the exchange server version .
This one below is for exchange 2016 . Highly recommeneded to take it from a working mailbox.
If you skip this one it works but it will throw out a error later if you enable archive mailbox for the same user.

Set-ADUser $_.samaccountname -add @{msExchVersion="88218628259840"}

ArchiveGuid can’t be set on this object to enable archive mailbox
