Hi guys

We have an Exchange 2010 environment on Windows 2008 R2.

How do you export all of the mailboxes, their usernames/aliases but also the organisational unit that their usernames are part of into a CSV?

You already helped me export the mailboxes and their usernames, which worked great. I would like to add organisational units into that CSV also, is this possible?

Thanks for helping

We deleted users never logged in from Server 2012 R2 AD and the Exchange 2013 shared mailboxes for the users were removed. This was inadvertent, as those users should not have been deleted (owner of the shared mailbox). How can we reverse this action? I know the mailboxes aren't actually deleted for 30 days but don't know what to do to get them back. I also can't recreate some of the shared mailboxes because Exchange complains the user exists... but it's actually deleted

Much thanks!!

Windows 2016 Data Center

I have 2 Exchange 2016 Servers setup as a DAG

I had a Exchange 2010 Server with all my mailboxs on it.  I migrated all the mailboxes to exchange 2016 mailbox database.

I shutdown the exchange 2010 server but when I go the my EAC I still see it referenced

How do I remove that old exchange 2010 server from my Exchange 2016 setup

I see the databases, virtual directories send connector etc

How to completely remove this?

Thank you
Options for synchronizing the GAL between three Exchange Organizations.

Hello Experts,

Is there an easy and economical way nowadays for synchronizing the GAL between different Exchange Organizations?

I know that back in the days there were super expensive and complex tools, such as MIIS 2003 and IIFP 2003. (Support finished in 2008). After that Microsoft released ILM 2007 (Still expensive and complex). Alternatively, there is a GAL Sync tool that sounds exactly like what I need, and the cost is a few hundred dollars.

But despite of these things, is there another simple tool or process that you know? or something more modern? I remember that a few years ago, what I did with a client was a PowerShell script to synchronize the directories and it was quite challenging to administer deleted users (avoid that they stay permanently at the destination Exchange Organization).

Let me know please what is the current solution that is used for this. I am interested only in sharing the directories (names and emails) between the three organizations.
Just installed Exchange 2016 into an existing 2010 environment. Everything works great. I got the namespaces corrected on 2016 AD side and SSL cert going. Mail flow works and creating/migrating a user onto a 2016 DB or to  2010 DB works. OWA works. Autodiscover works. What I am testing now is where I am stuck.

If it log into a machine as a 2016 DB user and open outlook for the first time - outlook 2010 will only connect and function on cached mode. if I leave cached unchecked, it says Microsoft must be online, failed to authenticate. Not sure where to look.

Office is updated
Services and Server have been rebooted (all services are started)

I need Help i am trying to add my failed Exchange Server 2010 to a DAG but when i ran the command in the image and getting the error. Please for your assistance.Adding-to-Cluster.JPG
Hi Experts, have an issue with an Exchange 2010 server which will not send internal or external emails until a reboot is performed. After running for a while it will stop sending internal/external emails again and a reboot will start email flow again

There is sufficient disk space on the server, there are no messages stuck in the Exchange queue, no errors on event viewer, all databases mount, AD/DNS servers resolve correctly from Exchange, mail flow tests show no issues

There is a smart host Barracuda used for sending receiving emails but I would think at least internal emails should route before hitting Barracuda and those would not be affected

Any ideas where I should look next?

Hi guys

One of our users has a Mac, with Outlook 2011. They can't be put on the domain as they have a personal laptop, so they are accessing their emails from Outlook via the OWA url link which is

Seeing as they're accessing information like this, they can't access the directory service and contacts aren't being pulled up from AD. So, I just wanted to know if anyone knows what to enter in the 'Directory Service' section of Outlook 2011 and what to enter in the 'URL'? Along with what port number?

Thanks for helping

I currently have 2 separate PST files from Exchange Discovery searches.
One was performed by a tech who missed some details and this forced me to run a new discovery with the added info.
Now I need to find a way to compare the 2 PST files and create a new PST that only contains the emails my search found that were not included in the previous search.
At this point, I can't seem to find a good solution to this issue and any help would be greatly appreciated.

Exchange 2010 stops sending and receiving messages after 8-9 hours. Suddenly, like 5 days ago, problem occured first time. I do not know where to start troubleshooting. After restart everything is OK for another 8-9 hours. Antivirus (ESET) uninstalled, but problem remains. Exchange 2010 with latest updates (updates were installed after problem appeared). OS W2008 with latest updates (automatic).

No error in event log seems to be clear and indicating any problem. Please advice where and how to start?

many thanks

I have a problem with Exchange Server 2016 and the queue log files:

I have more that 10'000 items in I:\exchange\transport\queue which is my transport queue.  Exchange does not seem to be able to cleanup old log files:

Hi all. I'm having issues with a customers Exchange 2010 server (14.02.0390.003), running on Windows Server 2008R2
The symptom, it stops accepting email. At this point I can't telnet to it locally like this 25
The MS Exchange transport service cannot be started or stopped easily.
I have managed to rename the folder C:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\data\Queue
but had to do this by disabling all the Exchange services, restarting the server, renaming the folder, then enabling, and starting all the services again.
This worked for the whole day yesterday but stopped accepting mail again last night.
The other problem is I can't stop the EdgeTransport.exe process to rename the Queue folder again.
I have tried taskill /f /pid 9968 but it says
ERROR: The process with PID 9968 could not be terminated.
Reason: There is no running instance of the task.
If I try to rename the file mail.que it says "cant be completed because the file is open in edgetransport.exe"
Now I'm stuck, can anyone please help?
Running an old Exchange 2010 server for a small client. Problem started out of the blue. The indicators were that SMTP connections were timing out from both the Outlook clients and the Internet mail relays. Service was apparently running, but could not be stopped. Would just hang at "stopping". TASKKILL without force would say that it could not stop it, and TASKKILL with /FORCE said it was not running, yet it was listed by TASKLIST.

Only way to get the server back up and running is a full reboot. When it started to happen, it happened about every 8 hours. After deleting the old mail.que, which was 250MB, it now gets to 12hrs at a time. It is up to SP3 and Roll-up 21, although the admin interface still displays the basic SP3 version, but from what I have read, this is reasonably common, and the versions on the executables seems to be correct.

It isn't out of disk space, it isn't out of RAM, there are no back pressure warnings, in fact there are no warnings at all. Store cache has been limited and the box sits at 65% RAM. I have been looking at all sorts of options, even restarting the service every hour, but that didn't help.

Nothing in the anti-virus logs that would indicate it was doing anything. No clue anywhere in the Event Logs, nothing that I can see in the transport logs.

I am very confused :-(

I am completing a mandatory audit and need to look up the following information for our Office 365 domain:

1. The city and state where our Office 365 domain data is stored

2. The encryption type that is used to encrypt our Office 365 data

I have already spoken with several Office 365 representatives (and have provided them with our Office 365 domain info) and they have either told me this info can't be released or are unsure on how to lookup this information.

That is why I am hoping to find a way of looking up this information myself within our Office 365 site (after I have logged in with my admin account).
We are having an issue with our Exchange server

We are only a small organisation (approx 12 users) using 2008r2 Exchange 2010 sp3 48gb RAM 1tb drive

The server is a DC and file server. It’s not a SBS.

There is loads of free disk space on the server.

We have backup assist software to backup the system and spam fighter software to provide spam filtering for the server.

The server stops sending and receiving mails at approx 4 pm every day and takes a reboot to start sending and receiving mails again. I thought that this may be a “stress” related issue but having read a post regarding this and disabling monitoring we still have this issue.

The server has 2010 exchange SP3 installed the spam fighter and backup assist software is up to date. I have had a look at the mail queues and all seems OK
Exchange 2010 on a windows std server 2012.  Recent problem (last 3 days). Outlook and OWA can connect, but no emails get sent or received after approx 6 hours of uptime.  Rebooting the exchange sever 'fixes' problem for another 6 hours or so. Exchange server does not appear sluggish and I can remote desktop in.  Restarting exchange transport service does not remedy the issue.  Just a complete reboot.  

I can post logs if useful.
Good afternoon everyone!

I am performing mailbox migrations in a Hybrid environment!

Why am I having a problem in 3 boxes where I do not change 2013 are they? Archive while performing sync is giving the following error.

I just want to know what are the options in blocking external calendar invites in one or particular mailboxes in exchange 2016. we want to block external  users to be able to sent invites to one of our inboxes. any information in this regard will be appreciated.
I have a question about email servers.  In this instance, it is sending email between two exchange servers.
The internet header indicates the message was sent/received with TLS 1.2.  Does this mean that the messages are encrypted?

Can we use this to pass confidential information and feel safe that our traffic is unreadable.  This is a medical facility with HIPAA concerns.
hi guys

So I got some help from EE experts to run a command in Exchange shell to export all mailbox statistics/data.

One of the important things is for me to work out the LastLoggedOnTime so that I can segregate the oldest mailboxes from the actively used ones.

I ran a tool called Inactive Users Tool by Solarwinds and exported it. When I compare the last logged on time of one user from the Exchange shell formula to the data exported from the Solarwinds one, they are different. I have many users who have not logged on for years, but somehow are showing as two days ago in the Shell statistics.

Perhaps the Solarwinds tool is using the Inactive users by looking at a different attribute?

Any ideas on why that would be?

Thanks for helping
I have two questions.  I've been referencing the video found here in regards to Exchange Online Hybrid Mode With Exchange 2010.  Below are my two questions.

There is a step where it asks to enter in the mail flow FDQN, however, I have a dedicated server running GFI Mail Essentials that sits at the edge of my network and filters mail.  It then sends all mail to my on prem Exchange.  And in regards to Exchange sending mail it uses a smart host / relay setting to send all mail to my GFI Mail Essentials server.  With that said.  Do I enter in my GFI Mail Essentials FDQN here ?

In regards to AAD Sync.. Does this wizard enable AAD sync or is that something I need to do before hand?
Hi guys

We have Exchange 2010 SP3 and I was hoping you could help me pull out an Exchange report that will put everything below into separate columns in an Excel file. It can be ascending or descending based on mailbox size:


AccountName or Alias
MailboxSize (GB)
Mailbox Database Name

Can you help me with this?

Thanks for helping
we have a windows 2012 server std rel 2 running exchange 2010 which since recent updates has developed a problem with (I do not know that the updates caused this of course), it would appear the transport service.

We can access the server locally and remotely running owa (even when hung), but for some reason mail does not flow in or out.

The transport service is running ok, but when we try to restart it, it hangs, saying it did not restart in a timely fashion. if we kill the transport service, we cannot restart the service.

The only way we find to resolve this is to restart the whole exchange server.

It then runs ok for an hour or so then just stops again. The transport service says it is running, but we do not have any mail flow.

I have just noted a warning in our Application event log :-

Scource - MSExchangeTransport - Event ID 1035

Inbound authentication failed with error LogonDenied for Receive connector default "server". The authentication mechanism is Ntml. The source IP address of the client who tried to authenticate to Microsoft Exchange is

Can anyone advise how we can trouble shoot this problem?

Many thanks
