Hi All,

My Exchange Server 2013 DAG spreads across 5x mailbox servers VM in three different Data Center locations.
So each mailbox servers hold mixed of 2 Active 3 Passive or 3 Active 2 Passive mailbox DB.

After the nightly successful backup, I can see that the some of the current Mailbox databases are mounted on the server that is activation preference 2.
So the database is kept on mounting from one server to another one (changed daily after the successful backup).

Is this the normal behavior of DAG ?
Would there be any impact if I let it automatically failover to one server nightly or keep running on the passive node forever ?

Note here are the settings applied for all the Mailbox Database:

AutoDagExcludeFromMonitoring                        : False
AutoDatabaseMountDial                               : GoodAvailability
DataMoveReplicationConstraint                       : SecondCopy
ReplicationType                                     : Remote

And this is the Cluster Properties from one of the DAG member which should be replicated for all nodes:

cluster /prop SameSubnetThreshold=20:DWORD
cluster /prop SameSubnetDelay=2000:DWORD
cluster /prop CrossSubnetThreshold=20:DWORD 
cluster /prop CrossSubnetDelay=4000:DWORD
cluster /prop RouteHistoryLength=40:DWORD

I had a disk error that was fixed, however, it caused my Exchange 2016 EDB file to now show 0 Bytes. The database cannot be mounted. I have tried all eseutil commands, but they all give jet error -1206, and state the file is corrupt. There is no backup, as the disk error was not allowing a proper backup to be generated. Is there any way to recover? If not, how do you create a new "first container" database for administration and system files?
When i downloaded Hybrid Configuration Wizard on exchange server 2016 then this error is showing. tell me how i can solve this issue.
I was deploying hybrid configuration. when i run test connectivity then this error is showing. please tell me how i can remove it.
I have a user who's e-mails are disappearing when he tries to open them from his iPhone and they can not be seen on his phone or his computer.  The client uses Exchange 2010 and Outlook 2010,  Has anyone seen this and have solutions?
We use Exchange Server 2010.  My computer is a Mac with Outlook 365 client that connects to the corp exchange server to get mail.  I also have a PST folder that i created and manually move emails to it.  For testing, on the Exchange server, we enabled ARCHIVING feature on my mailbox and the rule is to archive 3 years.    ISSUE: after this was turned on it went through my PST folder and seemed to remove all of my emails between 2017 - 2014.   I can't locate these files.  I've since turned OFF arching on my mailbox but I'm unable to retrieve the missing emails.  Even if I re-import my pst folder (from my hard drive) the emails do NOT show.  Is there a way to retrive the lost emails?
Today's appointments were missing from my iphone calendar. I disabled calendar from the iphone, ALL appointments were removed. I re-initiated the calendar, but now i am missing ALL appoitments.

Yesterday we completed my migration to outlook 365.

Any ideas? I have tried
- resetting networks
- re-installing the email exchange account
- toggeling sync of the calendar

Any advice would be appreciated.
Ok - This is how my week is going, need to see if it is OK to uninstall Exchange 2013 from Server.

Created New VM and installed Exchange 2013
Got to the point but did not do it, where I recert the New Exchange and the old Exchange.
I did do a Domain Prep/ ADPrep so the Active Directory Accounts are there for the EX2013
I tried making a backup and it failed. Found out that the Dell Server has bad blocks on the Virtual Volume. Tried swapping Disks, still reports Bad Blocks on the virtual Volume from Dell and still cannot backup.
I then tried to Migrate from 1 ESXi Server to another, failed. (The VM is on local datastore)
Tried to perform VSphere Replication to the other ESXi Server- Sync is currently stuck at 19% for hours.

I am preparing to destroy the Volume created by the Dell RAID set, but before I do that, the 1000 Point Question:
Since Exchange 2013 currently does not have any mailbox's and Exchange07 isnt really talking to the 2013 Server yet, is it safe to uninstall Exchange 2013 at this point and remove from Domain?
If so, then I am going to Destroy the Volume after that, and install a new VM Exchange 2013 Server and use that one.
I am pretty sure that the only thing affected was Active Directory, which has the new Exchange Accounts.
Hey guys.  I've got a situation where I am going to be migrating from a server running Exchange 2010 to a brand new Exchange 2016 server.  There are about 400 end users using this server.  I'm comfortable migrating the data over, but I'm concerned about having to reconfigure the Outlook profiles for all those users.

What is the best practice for doing this?  I can't imagine keeping the servername the same would work.  

Since there are so many users, i want to minimize the time needed to reconfigure all those Outlook profiles

Would enjoy hearing your thoughts.
I have Exchange 2007 and I want to enable Outlook Anywhere for the purpose of office 365 staged migration.
We already have a working OWA 2007 for the users.
I have completed steps a) and b) so far.
a) I have installed Enable RPC over HTTP
b) On the EMC- Sever Configuration-Client access- I have Enabled Outlook Anywhere

The DNS and NetBIOS name of our Domain as attached in the snapshot. This is FYI and let me know if you need any further information.
Now to make the auto discover work, not sure what else i need to to do.

1) Do I need to create A record for autodiscover internally on the DNS.
2) I had renewed the SSL certificate procured from Trustico for Exchange 2007 server 12 months ago and do I need to now put autodiscover entries in the certificate.
3) Do I need to create a DNS forward lookup zones for my domain.
4) Do I need to add a “A” record for the autodiscover service on our public DNS.

Please suggest what is the easy way to make autodiscover work with my current setup.

Thanks any help and tutorials would be great.

I have an user with iPhone 6 and 7 plus. her device is making lot of foldersync request. is it normal for device making so many foldersync call throughout the day ?

issue I'm having is, when device keep making Folder Hierarchy sync request, sometime the device go through full sync and reload entire mailbox.

I turned on the debug log for the device, I see <SyncKey>0 </SyncKey>, zero mean device is requesting full foldersync and sometime it leads "Invalid synchronization key or synchronization state corrupted on server" with status code 3.
The device is constantly doing full device sync almost in every couple days.

my question is, why the iphone device is making so many foldersync request ? is this coming from device issue or is on Exchange server itself ?

the user do have lot of folders over 3500 folders but she isn't creating new folders everyday. but her device still making lot of folderSync and then device did a full sync.

RequestBody :

We created a shared mailbox but we wanted to see if there is a way to send an alert or notifications to certain staff when an email arrives in that mailbox without forwarding the message.

I didn't see anything in the rules on the server or client other then text messages
I had this question after viewing Exchange 2013 Hybrid setup - HCW0 No federation trust is configured for this organization.

We have had an Office 365 tenant for years now, but have never migrated to it. Now that we wish to do so, I am getting the error in the subject line. Microsoft has worked on our inability to create a hybrid config off and on for the past year or more, with ZERO progress.

I see that one solution is to create a new tenant...does that mean creating an entirely new Office 365 account setup for our entire K-12 school district?  It's hard to imagine that switching to an entirely new Office 365 tenant domain name would not be a huge headache!

Perhaps I just don't understand the process. It was mentioned in the solution article listed above.


I have a small business customer that I'm moving to Office 365.  There are just two users at this company.  In order for them to move to Office 365 Mail, they'll need Outlook 2016.  Exchange 2007 doesn't work with Outlook 2016.  What is the best way to make this happen smoothly?

Timing is of a concern since they make and ship parts.  Changing their MX record and getting their email loaded into Outlook 2016 will be a challenge.

Here's what I'm thinking.

1.  In their current older version of outlook, which works with Exchange 2007, save their email, calendar items and contacts to a PST file.

2.  Download and install Office 2016 from their Office 365 accounts.

3.  After Outlook 2016 is installed, point it to the Office 365 Exchange Server

4.  Import PST file into each user's profile

5.  Change MX record to change from their on prem Exchange Server to Office 365.

Any thing that I missed?


After a recent update we are experiencing problems backing up our 2016 exchange server with Barracuda Yosemite V10.5.

We have a single Windows 2012 server running 2 x hyperv servers. One being our domain controller and the other is our 2016 exchange server.

When we run the backup on our hyperv master server, both the hyperv host and the domain controller backup ok, but the exchange 2016 server fails.

on looking at the logs we see the following :-

" The statement BACKUP LOG is not allowed while the recovery model is SIMPLE. Use BACKUP DATABASE or change the recovery model using ALTER DATABASE."

My question is how do we change this setting for exchange 2016? ie from SIMPLE to ALTER DATABASE?

Any assistance much appreciated.

Greetings Shubham and welcome.
Only a quick question, trying to ascertain the best practice to deal with leavers.

Q: What is the best policy for leavers and retaining email, Auditing etc?

We have quite a few leavers on the project but need to retain all email for these leavers.

We have a pure Office 365 environment.

What are the implications on journals after deleting the users account, soft and hard delete.

Outlook Web Access zeigt folgde Meldung:
OWA Fehler: Die Nachricht kann nicht gesendet werden, da ihr Gerät nicht mit dem Internet verbunden ist.

Das ist quatsch da der OWA Server sehr wohl eine Internetverbindung hat. Über Outlook kann man Mails senden. Bei einem anderen User am gleichen Computer funktioniert es.

Kann jemand helfen?
I have a SBS server 2008 running Exchange 2007.
I get a lot of spam where the subject contains an * or ! to replace words of a sexual nature. The normal business email subjects  never contain these characters so I would like a way to apply a filiter at Exchange.
Is this possible?
Hi all,

We have an Exchange 2010 and would like to export a mailbox to PST using scripts.

We would like to export the entire mailbox to pst with all sent/received emails up to 15th August 2017. How can we do this?

I found this script but not sure about it.. it needs modification

New-MailboxExportRequest -Mailbox testc -ContentFilter {(Received -gt “01/01/2009") -and (Received -lt "01/01/2010")} -FilePath "\\server\migration\testc.pst"

If there's anyone out there that can think back far enough, I have a friend that's still using SBS 2003.  At some point last week it disappeared off the network.  We did manage to get it back on the network by using an alternative onboard NIC, but since then multiple services refuse to fire up.  There are multiple error codes, all seem to point at dependancy issues.  Among many, the Workstation Service does not start, along with many of the Exchange Services.  Has anyone experienced something like this historically and resolved it?
Hi All,

I'm running Exchange server 2013 standard edition, and I tried to remove some of the old AD account from accessing the shared mailbox, using the PowerShell command:
Get the SID: Get-ADUser -Identity Kacung.Semprul
Remove the user: Remove-MailboxPermission -Identity Shared-MBX-1 -User "S-1-5-21-3684462478-1056977450-1152882164-8921" -AccessRights FullAccess -InheritanceType All -Deny:$true

But somehow I can not go through due to this error:
can't remove the access control entry on the object because the ace doesn't exist on the object

I've tried:

But still not working for me.
Microsoft recommends leaving an exchange server on premise to edit Directory Synced objects post hybrid migration (assuming you leave AD Connect up).  Either 2010 or 2013 (with a Hybrid Exchange License if you need one).  Using ADSI edit is "not supported".

But the mailboxes of course no longer show up in the EMC as a mailbox you can edit (for say SMTP addresses).  You can connect to the office 365 tenant via the EMC, but you can't edit anything coming from on premise.

How exactly do you use the EMC to modify directory synced objects?  For instance smtp addresses?
