Recently replaced the Federation Trust Certificate on an Exchange 2010 SP3 server.

When running the Test-FederationTrust command the following output is shown:

RunspaceId : 9a7a44a8-##-92c5-7ae5f2f34979
Id         : FederationTrustConfiguration
Type       : Success

However, the certificate referenced in the property for OrgPrivCertificate in the FederationTrust object isNOT expired.  It is the newly created certificate.

Any suggestions please?

Hi there. I used to have an old hotmail/outlook account with the following address: pedrohenriquebarros2010@hotmail.com

As you can see it is from 2010, and hotmail pretty much doesn't exist anymore. I tried to acess that e-mail and it said it doesn't exist. So i thought: "Ok, let's create it". I did create it again, but when trying to login i rceived this error:

X-ClientId: F41D9C7CC7944A9791F7252C651589E0
X-Auth-Error Microsoft.Exchange.Clients.Security.MailboxNotFoundException
X-FEServer RO1PR80CA0224
X-BEServer RO2P152MB3469
Date:13/06/2020 12:37:06
InnerException: Microsoft.Exchange.Data.Directory.CannotResolveTenantNameException

Is there a way i can have acess to my account again? Because i want to start playing and old game again that still working, but the game is asking to receive an e-mail for confirmation... Thank you!

Updating from CU2 to CU23, precautions

Hello,

I recently took over the IT roles for 2 companies and am new to using Exchange. Through months of working on these servers I've learned enough to do the simple stuff. It recently came to my attention that they haven't been updated since 2013 (SERIOUSLY?!). Some users recently can't use the calendar on a computer (but on their phone it works fine), as well as OWA problems when searching for old emails. I'm hoping this cleans things up, among other things.

Anyways, what precautions should I take before updating these servers. They are both on-premise at a M-F site. I'm running a full backup using Carbonite and am cautious about this update leading to other problems. Also, about how long would this take? I'm planning on doing it over a weekend.

Thanks!

Is there way to achieve this.

Exchange removes MIME preamble and breaks DKIM signature

Hello,

I am sending a message to two recipients from an Exim 4.84_2 server. One of the messages is forwarded through an Exchange 2013 server while the other is delivered directly to the recipient's server. Exchange keeps removing the line "This is a MIME-formatted message.  If you see this text it means that your E-mail software does not support MIME-formatted messages." from the message and this breaks the DKIM validation as the body's hash doesn't match with the one in the DKIM header.

The body of the message which is not forwarded through Exchange is this:

This is a MIME-formatted message.  If you see this text it means that your
E-mail software does not support MIME-formatted messages.

As you can see, the only diference between the two messages is the missing first lines (the MIME preamble).

So you know how to avoid Exchange changing the message body?

Kind regards,

Hi,

The background

We have a mixed estate and are moving users from Exchange 2013 to Exchange 365

When trying to share a calendar for a user on the onprem(2013) to a user that has been migrated I get this error message:

One or more users cannot be added to the folder access list.  Non-local users cannot be given rights on this server.

Is this a know error and is there a fix?

Outlook 2013 being used if that makes a difference.

Cheers

How to find root cause for same mail being sent 2 times from a application

June 22, 2020, 7:51 am
$

We have a application that relays email through exchange 2010 CAS server (Hybrid setup).
We are seeing duplicate emails sent by the application for the same job.
According to the vendor the application only waits for 20 seconds (20000ms) for the mail to be sent. If no response is received from the exchange server in that window the application will think the job failed and try it another time. That's why application keep sending the same emails out.
This results in users getting same email 3-4 times on occasions.

I grabbed the header of one of the emails that was sent 3 times to user.
In header analysis I could only see a delay on the second hop (hop to mail.protection.outlook.com).
Would second hop matter from the application perspective?
My thought is that the smtp session is between the application server and the CAS server. So as long as the mail was handed over to the CAS server then the application doen't know what happens to the mail after that and thus the second hop should not matter.
But another engineer thinks that as we are consistently(about 40% of emails) seeing delay on second hop (upto 10 minutes on occasions), that could be affecting the application.
Is that correct?

And how can I troubleshoot why the application can't handover the mail to CAS server in 20 seconds and thus sends it second time?

Hello,

I have a service written for fetching emails from outlook using EWS. This code was written 3 years back and has run without any issues.

Today Morning all of a sudden there was this error:

Microsoft.Exchange.WebServices.Data.ServiceResponseException: The mailbox database is temporarily unavailable., Cannot open mailbox.

After that I started getting below error:

Microsoft.Exchange.WebServices.Data.ServiceResponseException: The property can not be used for sorting or grouping results., Sort/GroupBy isn't supported for property IsRead.
   at Microsoft.Exchange.WebServices.Data.ServiceResponse.InternalThrowIfNecessary()

   at Microsoft.Exchange.WebServices.Data.ExchangeService.FindItems(FolderId parentFolderId, SearchFilter searchFilter, ItemView view)

Below is my code to fetch emails:

below first line is throwing the error.

Any help is appreciated.

After migration of Exchange 2013 shared mailbox to Office 365 in a full hybrid enviroment, only users in Office 365 with a license can open the shared mailbox from owa. All users can open the shared mailbox from Outlook 2016. Is this a normal behaviour?

i have a resources and account AD forest that contains both exchange 2013 and user accounts as well.

we are going to migrate user accounts and computers to the another forest B but mailboxes will stay in forest A.

so with moving SID history of users from forest A to forest B, will users be able to continue accessing to their mailboxes?

or should we create linked mailboxes for them in the resource forest, in this case should be extend the AD schema of the forest B with Exchange Binaries?

thanks in advance

Step 1:

$user = Read-Host 'Please enter new mailbox username'
Enable-remotemailbox -identity $user -primarysmtpaddress $user@company.com -remoteroutingaddress $user@company.com
Enable-remotemailbox -identity $user -archive
Write-Host "To complete mailbox creation run a DirSync"

Step 2: after waiting 10 minutes

$user = Read-Host 'Please enter mailbox username'
set-remotemailbox -identity $user -emailaddresses @{add="$username@company.com"}}
