I am using Veritas BackupExec 20, running on a SAS-connected tape library drive currently in trial mode and trying to run an Exchange backup. I have 3 Exchange servers in a DAG and all databases are mounted, healthy and have no failed replicas. We are using Exchange 2013, updated within a month of the most current CU. Two of the servers are running Enterprise and the third runs SE. The three servers are "MD" and "MT" (The enterprise ones) and "PM" is running SE. I currently have the databases running on the "MT" and the "PM" servers because the backup wants to use the passive copy, which is on the "MD" server and is in the same room with the tape drive, so will have the shortest backup time (There would be network congestion issues trying to back up 6TB over the links to the other servers!). When I run the backup, it gets the first two and a half TB then quits with this error:

Completed status: Failed
Final error: 0xe0008516 - The database specified for the snapshot was not backed up because the database was not mounted.
Final error category: System Errors

For additional information regarding this error refer to link V-79-57344-34070

and that error leads to this error in the job log:
V-79-57344-34070 - Snapshot Technology: Initialization failure on: "Microsoft Information Store". Snapshot technology used: Microsoft Volume Shadow Copy Service (VSS).

Snapshot technology error (0xE0008516): The database specified for the snapshot was not

I have a particular problem I'm trying to troubleshoot. I am looking for a powershell script to search a particular mailbox to figure out how many messages are in the inbox that were received on a particular day. I know I can get some info from the transport log powershell scripts but I would like the data directly from the user's inbox vs the transport logs. Any help is appreciated! We are running exchange 2010.

I'm trying to search for eamils that contain a specific attachment. When I ran the script below, I believe it grabbed any emails that contain attachments that contain any words in the name of the attachment in the script, not the entire phrase "This is a test*"


How do search for the exact phrase?

get-mailbox -ResultSize unlimited | search-mailbox -SearchQuery 'Attachment:"This is a test*"' -TargetMailbox mailbox -TargetFolder foldername -LogLevel full

Hi there,

On my Exchange 2016 environment, I have to set the user mailbox maximum outgoing message size as 0 (EAC>Mail Flow Settings > Message Size Restrictions > Sending message size). At the same time, the auto-reply message could not send out. Is there a way to make the OOF(auto-reply) happened?

Thanks!

Hello Experts, I have Exchange 2013 CU20, with AD2012 R2. I have setup AAD Connect with pass-through authentication, enabled Modern Auth, Single Sign on, and enabled Password hash synchronization aswell on the AAD connect servers. I have also ran the Exchange hybrid configuration wizard, with centralized mailflow. We have a few authoritative primary domains in on-prem which user accounts are stamped with. I have added and verified these domains in our Office 365 tenant. and the user objects/ identities are being replicated to Azure AD just fine. since the users will be doing pass-through authentication and will not be leveraging our on-prem ADFS, i believe leaving the domains as managed in Office365 will be fine?

i assume this will be fine? My question is, i know if a domain is federated, and if it is added in Office365 tenant as a federated domain, it needs to become federated with the switch  -SupportMultipleDomain. Does anything similar to that need to be done for the domains that are showing as managed in Office365 portal, if we have multiple domains added in Office 365 as managed? I could not find any Microsoft article that talks about this, and wanted to make sure.

Please let me know, thank you in advance

Hello Experts. I have Exchange 2013 CU20 with AD2012R2 in my environment. I would like to go to CU21 for Exchange 2013. I have a few questions:

1. Although I see that /PrepareSchema is not required according to this article: https://blogs.technet.microsoft.com/rmilne/2018/06/19/exchange-2013-cu21-released/
    is there any harm in running /prepareSchema?

2. I tried to do a /prepareSchema in my staging env DC, and received an error stating that i need to install 'Visual C++ Redistributable Packages for Visual Studio 2013' before running the command. Do i really need to install this on my DC aswell if i would like to do a /PrepareSchema? I will do a /PrepareAD prior to installing CU21, i believe that /PrepareAD will through the same error that it needs 'Visual C++ Redistributable Packages for Visual Studio 2013' before running the command. I am not a big fan of installing extra piece of software on DC's, is there any other way of going about this?

3. According to this kb: https://support.microsoft.com/en-us/help/4099855/cumulative-update-21-for-exchange-server-2013  i see that .Net Framework 4.7.1 is now required. we are currently on .Net Framework 4.6.2 . Do I need to install 4.7.1 myself first prior to running CU21, or will CU21 install the required .Net Framework 4.7.1 itself during the update?

4. According to the above kb, it also mentions that 'Visual C++ Redistributable Packages for Visual Studio 2013', is required. will CU21 update install this component …

With Skype for Business/Exchange Online, and a conference room that has a Polycom group Series, how do you logistically use that for Skype Meetings?
Is the Polycom supposed to “be the room” and this you name it the name of the room?  
Or do you create a room for the “room” and create a second “resource” for the Polycom Skype device?  
Further, when you schedule Skype meetings, would there ever be a need to send FROM the top or FROM the Polycom Skype Calendar, as in manually creating the event on the calendar. Or does a Meeting Organizer always simply add the Room and/or Skype enabled Polycom device AS an additional “recipient” in the meeting invite?

Hello experts,
Trying to change the meeting duration of meetings from 30 minutes to 15 minutes interval. How do we go about it in Office 365 Outlook Client and On-Prem Outlook (2016)? We haven't started moving the users to the cloud so we have to both enable it in the cloud AND on prep to test.

Thank you!

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.

I have a Exchange 2016 DAG across 2 sites, soon to be 3. The 3rd site will be in the US and have a Exchange DB created on it to serve local users. There will be a copy of that database on  2 of my current exchange servers here for redundancy.

My question is, if I activate the US DB copy on one of the Exchange servers here, shut down that host and have it offline for 2 days while in transit will I have an issue when it is up again in the US? Will the database simply copy the changes it missed and eventually become available to be activated? Is there anything special I need to do like suspend the now copy?

Thanks!

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.
