Answer 1

@Xzsssss

All 3 are null

SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c} is not in there.

Answer 2

Hi @PABLO ,

We could get some useful message from the errors you posted, like:

Write-ExchangeSetupLog -Info ("Cannot find E-discovery arbitration mailbox with name=$name.")

This refers to the error message that will be wrote to the ExchangeSetupLogs.
Based on my knowledge, this is because something is wrong of the arbitration mailboxes.
So you could first check them with:

Get-Mailbox –Arbitration | Select Name,Database  

If it's right, the result will be five databases as this doc described: Recreating arbitration mailboxes
Or it's like: https://www.petenetlive.com/KB/Article/0001221

Answer 3

Hi @PABLO ,

From the result we could see the following arbitration mailboxes(System mailboxes) are corrupted, so we should first repair them to install the update.

1. SystemMailbox{1f05a927-d349-42cf-a6a6-f5aea5feab7c}
2. FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042
3. SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}

Please first check it with:

1. Open ADSI EDIT and connect to default naming context partition.
2. Expand CN=Users so you'll find the above CN=SystemMailbox and CN=FederatedEmail units, right click the corrupted ones and click Properties.
3. From the Attribute Editor, find homeMDB, check if it's <not set> or null, if so you could copy the right value from the other system mailbox like SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c}.
4. If the homeMDB values of these system mailboxes are good, you could consider recreate them with Recreating arbitration mailboxes

After fixed these errors, retry installing the update.

Lou

Answer 4

Put in a call with Microsoft. The Distinguished name was copied into the homeDB value. After this was done, reran the update and all was good. Thanks for your help.

Answer 5

I was getting somewhere wilh this https://learn.microsoft.com/en-us/exchange/security-and-compliance/in-place-ediscovery/delete-and-re-create-default-discovery-mailbox#Overview

Add-MailboxPermission "DiscoverySearchMailbox{D919BA05-46A6-415f-80AD-7E09334BB852}" -User "Discovery Management" -AccessRights FullAccess -InheritanceType all

and I got error

Add-MailboxPermission: The operation couldn't be performed because 'DiscoverySearchMailbox{D919BA05-46A6-415f-80AD-7E09334BB852}' matches multiple entries.

this sounds like what stopped the installer.
