How to cancel mail forwarding ?

Question

Hi. 3 servers Exchange 2019 - on-premise.

On a single server database only for archives. This server is currently unavailable.

I cannot apply the mail forwarding settings in ecp, in the user profile. Server unavailability error.

I cancelled the redirect using Powershell:

Set-Mailbox -Identity bulgakova -ForwardingAddress $null

But the forwarding still works:

Timestamp EventId Source Sender Recipients
--------- ------- ------ ------ ---------- --------------
22. 08.2022 10:05:32 RECEIVE MAILBOXRULE bulgakova@keyman .com {nebogatov@keyman .com}
22. 08.2022 10:05:33 DELIVER STOREDRIVER bulgakova@keyman .com {nebogatov@keyman .com}
22. 08.2022 10:07:07 RECEIVE MAILBOXRULE bulgakova@keyman .com {nebogatov@keyman .com}
22. 08.2022 10:07:07 DELIVER STOREDRIVER bulgakova@keyman .com {nebogatov@keyman .com}

Can I somehow cancel the redirection while the server is not available ?

Due to this server is not available, we cannot remove this configuration in a normal method. Here may be a workaround for you:

If you want to remove the auto-forward configuration, you may need to recover the broken Exchange server first.

Use ADUC and enable the Attribute Editor under Advanced Features
http://woshub.com/active-directory-attribute-editor/#:~:text=The%20Active%20Directory%20Attribute%20Editor,shown%20in%20the%20ADUC%20console.
Filter on Only attributes that have values to make it easy to find, scroll down
then find the MSExchangeForwarding attributes and clear there

Answer 3

Generic Forwarding is when you forward to a SMTP address.
If you are forwarding to another internal mailbox the field is
altRecipient

Answer 4

Check outlook rules for that account.
