Hi all,

I'm about to demote an old SBS 2011 server. Hopefully the below will outline the environment:

1) We're on Office 365 and Exchange on SBS servers no purpose, the services are disabled
2) I've transferred the FSMO roles form SBS to another DC successfully
3) I've unticked Global Catalog for SBS in ADS&S so it's not a GC anymore.
4) I want to dcpromo it so I can turn it off

My question is:

A) Can I dcpromo SBS with Exchange still on there or would it not let me anyway?
B) If I have to uninstall Exchange first, am I safe to restart the services? I suspect they wont effect anything as it doesnt do anything anymore.

Many thanks,
Evren

Friday morning my on-prem exchange server starting giving Error 1 for all emails sent from on-prem SMTP to our student office 365 domain.

Error 1: 451 4.4.62 Mail sent to the wrong Office 365 region. ATTR35. For more information please go to https://go.microsoft.com/fwlink/?linkid=865268

I followed the advise and changed my O365 connector settings from smtp:xxxx.zzzz.nsw.edu.au & smtp:xxxxzzzznswedu.mail.onmicrosoft.com to smtp:xxxx-zzzz-nsw-edu-au.mail.protection.outlook.com.

Once this change happened mailflow for on-prem to student o365 domain didn't fix. And then all mail started getting Error 2

Error 2: Server refused mail at END OF DATA - 554 5.4.14 Hop count exceeded - possible mail loop ATTR34 [SY3AUS01FT009.eop-AUS01.prod.protection.outlook.com]

I have the following setup.

On-Prem Exchange 2010
On-Prem MailMarshal

O365 Primary: xxxxzzzznswedu.mail.onmicrosoft.com
Additional: zzzz.nsw.edu.au (staff accounts)
Additional: xxxx.zzzz.nsw.edu.au (student accounts)

For students mail flow is straight to O365 Cloud

For staff mail flow is via Mail Marshal. Marshal sends to on-prem exchange who passes onto O365 via the connector.

Hi,.. We have old Exchange 2007 in our Environment. We migrated to Exchange 2013 as staging and now we are on 365  with Exchange 2013 still running as Hybrid server. Also we have DC's on 2016 server. We are trying to Decommission Exchange 2007 from our environment. When we try to uninstall the Exchange roles we get an error: "Cannot find atleast one global catalog server running Windows Server 2003 SP1 or later in the local Active Directory site."

Can someone please advise us on how can we proceed on Decommissioning Exchange 2007. I think we need to use ADSI edit to complete our task as DC's on 2016 Server do not support Exchange 2007. Please advise..

Thanks

I'm working on an issue I have with a vendor. They are unable to communicate with our exchange server.  The following message was sent to us.


"A Purchase Order sent to this email address has failed because a “secure delivery could not be established.
If it is a valid email address, please make sure that your company white lists all emails from the @domaint.com domain so Purchase Orders can flow without failures.  Also, please make sure that your email can handle TLS encrypted emails.  Our ordering system utilizes TLS encryption. "

Hi,

I need to assign a user mailbox "full access" to all mailboxes in O365. Instead to do that can I just assign a builtin admin role which already has full access to all mailboxes?

Thanks

How do I prevent end-users from adding or changing their domain account / Outlook photo? I'm not even sure how they are doing this! I've got a couple rogue pictures of "inappropriate" images popping up. I am in the process of adding "official" head-shots of everyone so it appears in Outlook/Office, Win10 (via a group policy), and other apps. I'm adding the picture using the DameWare Remote Support tool, since it has an easy way to add pictures to the domain account.

We have on-prem Exchange 2013, Windows Server 2012 R2 Std (Active Directory), and use Office 2013 and 2016.

Secondary question: A user added a photo of a Minion with a banana. It was showing up in Outlook. I deleted the photo from his AD account, but it still shows up in Outlook/GAL. Why?

I deleted a Mobile Device for a user in Exchange 2013 EAC.  I would like to put it back.  How can I do this?  If I put the account back on the phone, it cannot connect to server and does not show back up in EAC - other devices work without issue.

We are transitioning to Skype for Business from an older product called Spark.  With Spark it is fairly easy for each user to populate their own
groups with contacts that are saved and used to IM thru skype.  How can we populate groups without adding them one user at a time. We have some fairly large
groups

Dear all,

I am having an issue with our Exchange 2010 System. Before i explain what i am facing, I would like to let you know, that i am at an absoulte beginner level regarding Exchange. So any additonal information on how and why Exchange works in a certain way is appriciated.

Here is the problem: When i try to move a mailbox from one database to a new one it takes ages to completed. I had a look into the LOG and found this:
Log of Mailbox move
Folder initialization took about 15 hours. Mailbox is still completing. And I would like to know why? And how can I tweak this, since a lot more mailboxes are waiting for me.

Thanks in advance for your help.

I'm trying to add an Exchange 2016 server to my infrastructure and to migrate everything there from an Exchange 2010 server. I'm following this tutorial: https://practical365.com/exchange-server/migrating-exchange-server-2016/

But I get stuck at the Client Access Name cutover since my DNS configuration seems to be different from the one in the tutorial.

So we've got an internal DNS server for our internal network, and an external DNS server (outside of our AD, of course) for our public addresses. But in the tutorial it seems like they're using the same domain name for internal and external purposes?

Anyway, my Outlook connects via RPC/TCP to the Exchange server using its internal name (serv-exchange.whatever.local). But I don't know where this has been configured? Can I force Outlook to use the external name (mail.mydomain.com)?

That would make the Client Access Name switch easier ... I'd just need to change the NAT on the firewall for mail.mydomain.com ... otherwise I would have to change the DNS config of the current Exchange server which would create all kinds of problems, I guess?

I've tested accessing the new Exchange 2016 server on a client with a modified HOSTS file (with serv-exchange.whatever.local pointing to the new Exchange 2016 server) and that works fine! But in order to do that on the level of the internal DNS I would have to point serv-exchange.whatever.local to the IP address of new Exchange 2016 server but then the connection to the current …

Hi ,

I have been handed over an Exchange / Office 365 environment without any documentation.

When I look at the EAC, I see 6 Exchange 2013 Servers with Mailbox/ Client Access role.

we have 2 datacenters and we have DAG with a member in each site. we have Exchange mailboxes on this DAg.

we have also 4 other servers with O365 name in them that makes me think that they are related with office 365. As there is no database on them.

I also know that we are not using any ADFS but we are just sync usernames so we have to enter password for Office 365 again.

My question is that to find an script to show me detailed inventory of the environment.

I am not able to find Azure AD connect server and wondering why there are 4 servers with O365 name in them. They might not be used .

without any documentation, I found it difficult to figure out what is what, especially we have both on-prem and office 365 users.

Thanks

Hello, we just recently moved to Exchange 2016 from SBS Exchange 2010, now we a send limit of 30mb on our emails. Through OWA, i can send this fine, but through mobile devices (we use mostly ipad's and iphones) it fails, even if i send internally or even myself. Is there something i am missing on Exchange that is blocking this?

FYI i talked to Apple and they said there is no limit on their devices.

Hi,  I am creating batches to migrate users from exchange online to Office 365. Some of the batches were completed by another admin in error. I need to find out what admin and also if there are associated logs for migration actions.

My Exchange server is managed by our parent company in a data center offsite.  They have recently mandated that mailboxes be <2GB in size so they have recommended that PST files be created and stored on our local NAS for users to move needed emails before a purge.  My concern is that the size of these PST files will be massive.  I have users that have mailboxes 25gb in size.  is there any guideline that can help me figure out how big these PST files will be uncompressed in a PST file?  I realize there are variables like the "compressibility" of attachments but I am trying to see what a best guess would be.

We just changed our email security gateway IP address to a local address and now we don't receive any external emails from our exchange 2010 server.
We changed the send connector information but the email is still not coming in. Is there something else we need to change?

Hi,

Since PC reinstallation, one user cannot open shared mailboxes from his Outlook 2016 (with Exchange 2010).
When trying to expland the mailbox, an error shows: "The set of folders cannot be opened. The file ".ost" is in use and cannot be accessed. Close program or restart.."

The funny part is that his online archive and another shared mailbox can be opened without any problem.

This is below what I already did (but received the same error when trying to expand the shared mailbox):
- restart computer
- Outlook in online mode
- delete/add permissions to the shared usermailbox
- Recreate OST file
- start Outlook in safe mode
- Repair Office 2016+
- Reinstall Office 2016+
- Create New profile
- converting the user mailbox to shared mailbox type
- Add permission to another shared mailbox and/or user mailbox in exhange. Then try adding the mailbox in outlook.

Accessing a shared mailbox is possible from his outlook web access..

The problem is obviously coming from local computer.
Do you please have any idea ?

Thank you

We are allowing one of our Software Vendors to relay emails from their Cloud Application on Amazon AWS thru our Exchange Server.  The application is sending notifications to certain people within our organization.  The emails are coming from an internal email address I created so its coming from our domain.  It was working perfectly then the software vendor changed AWS servers but kept the same IP Address and now we are only getting a few of the emails?  We did not change anything on our end and I am puzzled as to why it is no longer working?  Anyone have any ideas?  I had setup anew SMTP connector for them to relay thru and have checked all of the settings.  They set me up with a test site from their Server so I could test as I was troubleshooting.  I have had a few of the test emails got hru randomly, but most fail wit this error message:

Hi,

We are having a NDR message saying : " 550 Relaying denied " whenever we send an email from outside to one domain.

This domain is an Accepted domain in our Exchange Infrastructure.

If I try sending emails from inside (Local), the email is send/received, but I doesn't work from an external domain.

Any clues please on how to solve this problem?

Thank you in advane.
