I have a client with 2 exchange 2010 servers, one is very old/slow, it was operating as the primary exchange. The second exchange server is newer modern hardware with a lot of space. I have successfully migrated all mail boxes to the newer hardware exchange database. I would like to decommission the old server before it crashes and I have big problems. So what would be the process for promoting the newer exchange server and removing the old.. The public folders database is on the old server so I will need to move that as well.. Documentation for going 2010 to 2010 seems to be vague, or maybe I am not asking the right question.... Thanks in advance.

What is the easiest way to accomplish this :

I need to send a E-Mail to a group of former employees but I want it to appear as though it is an individualized message directly to them.

  • E-mail Must Appear to come from individual sending it
  • E-mail must go to multiple specified Individuals
  • E-mail Must not show other names on the e-mail (must appear individualized)

Have to use existing features of Exchange 2010.
Hi Guys,

We are having an issue with two mailboxes in Office 365.
These are brand new mailboxes - not migrated and not linked to onsite AD.

We setup the mailboxes successfully on the mobile phones, but setting the profiles up in Outlook failed.
Logging into the mailboxes online, resulted in an error:
Something went wrong, please try again again ... err:  Microsoft.Exchange.Data.Directory,ForestUnavailableException

After a password reset on one of the mailboxes, it asked for the time zone (logging on online)
After the time zone select we are getting "401- Unauthorized:  Access is denied due to invalid credentials"

We spoke to Microsoft, but they are not of much help up to this point.

Any ideas will be appreciated,
There are unfortunately already new mail in these mailboxes, and deleting / recreating these mailboxes are not an option

I just a tool from MS gallery site: Download Office365-Exchange-Tool.exe

And realized that this from AdminDroid

I'm confused now:

1- Is it a free tool or we will finish to paid at the end of trial period?

2- Because it is from MS site I'm suppose it's a trusted tool

3- Are all tool or script provided by MS in their gallery site have been tested by MS team?
I am trying to accomplish task where I pick and choose folders those get shown to only those users who have access to it. I know this can be accomplished by turning on Access based enumeration. I have a namespace pointing to particular folder share.

I got a question about applying ABE to this entire namespace which points to a particular share on the server, currently access based enumeration is NOT turned on.

Name space:  \\\CorporateShare
Name space server under this name space:  \\Server1\CorporateShare

Currently access based enumeration is NOT turned on.

\\Server1\CorporateShare contains 100s of folders which have specific NTFS permissions on various folders. I am assuming if I turn on Access based enumeration on the name share to gain this feature, check the box ( Right click on namespace, properties, advanced tab, check Enable access-based enumeration for this namespace)  it will apply to the entire name space. Therefore all 100s of folders will get accessbased enumeration feature and people will not be able to see folders they dont have access to.

I have read this article:

My questions:

1. Is it possible to Enable Access based enumeration on the name space and ONLY allow specific folders out of these 100s of folders to have ABE set ?  
( meaning I decide which folder will get  ABE and not all the folders ) . This is…
Hey guys,

I have a folder on one of our DFS shares, ( on server 2008 R2)  which I want to configure so its "invisible" to users who do not have access to this folder. Currently everyone can see it but get access denied message when they click on it. I want to configure it somehow that this particular folder on this DFS share is ONLY visible to users who have access to it.

Name space: \\\CompanyShared   ( X drive )

X drive have 100 folders within it, one of the folders is called - "Procurement" which have a security group assigned to it for specific people.

I want folder named "Procurement" only visible to people who are part of this security group which is applied to it and not everyone else.

Is it possible ? Can you point me in right direction ?  

Thank you in advance!

I have exchange online, outlook 2016, cached mode. Is there a way to force all outlook clients to update their offline address book faster than 24 hours? In Bulk? Even trying to manually update the OAB I still cannot get it to update properly. Any ideas?

Thank you.
Working for a financial services company, our users typically send out templated marketing emails to the business contacts they interact with.

Their emails typically have the same subject and text and lately tend to end up in the recipients' Outlook junk folders. They are not bulk emails though. A single sales guy typically sends out about ten to twenty of them per day.

Our third party outbound spam filter is set to let these through but the controls that Microsoft provides at Exchange Online (Office365) appear to be pretty much non existent.

Any ideas how to circumvent this?
Hi Experts,

I am in an upgrade from Exchange 2010 to 2016.

I want to test the new mailflow and I like to verify the incoming and outgoing mails are just coming from the new EXCH2016 server.

Do you have some quick checks for me please ?

We have one user who's email gets rejected from one domain.  Other users can send email to the person.  It also gets rejected when sent from OWA.

We are running exchange server 2016 in DAG setup. DAG is working fine. Databases are healthy.
I checked my exchange servers databases VHD's file size and notice that both servers databases VHD's size are not same. Please review the below image.
I checked database size in exchange servers and databases size are same on both server. Please review two images
1. Why VHD's size are not same? Do i need to worry about it? There is no error related DAG in event viewer. Everything is working fine if server one is down than database move into 2nd server but I really need to know why different size of VHD's.
2. You can see that 'E16DB1_55A2801F_......AAD.avhdx' also taking so much disk space like 550GB. What's the purpose of avhdx? can we reduce the file size without damage anything.

We are running Exchange 2013 Standard (CU 15) on a Windows 2012 R2 Standard server.

Can we implement an archive database with Standard or would I have to upgrade to Enterprise?

Thanks in advance,


I would like to search a specific exchange DL to find out who added a specific user. Using the Search-AdminAuditLog command can any one tell me the correct syntax?

I'm looking for a way to export all the contacts from each of my users Outlook (90 user mailboxes) in Exchange online to CSV so I can import into our CRM.

I have searched and found this script that uses powershell

Can anyone help update this to either loop all mailboxes or import mailboxes from csv?


I have a column with date but it also has empty value.

I advance filter I  choose: Before 201-09-10 or Equals = ""

It does not give me empty value but just result for:Before 201-09-10
Added Send As permissions to a user and it keeps dissappearing!  Went down the path of checking and found that this user has the Admincount=1 in AD attribute editor.  If you set it to "not set" it comes back an hour later when SDProp runs.  This user is only a member of Domain Users.  I added another group named TEST, made it primary and removed Domain Users, and it works!  So how do I "fix" the Domain Users group so that it doesn't enable Admincount=1, and how to remove Domain Users from being a "protected group".   Thanks!
We have a remote consultant working for our company who has been setup with an O365 exchange email account.  When trying to connect to his mailbox using the wizard in Outlook 365 (click to run) it tries to connect to O365 but then fails to connect.  He’s not even getting the Outlook dialogue box to enter his password.   It just spins then returns the default Outlook is struggling to connect.  It’s difficult for me to get access his laptop to troubleshoot as he’s in a different time zone.  He can access his mailbox via his mobile phone and the O365 portal direct from the same laptop and the same internet connection.  
Any ideas?
So I have an exchange issue with user .  She can't input a meeting into a calendar that she has access to.   We have tried everything from our end removing the profile reloading.   This is on prem exchange.   We are currently migrating users to the cloud.   Any idea how to fix this issue?   This is for an executive so I have to set this to high.

We have Exchange Hybrid setup as we are migrating from Exchange 2013 to Exchange Online.  

We have a user who has an on-prem mailbox and a cloud mailbox, I believe this has come about because the user had an Exchange Online license then later an on-prem mailbox was created for them.  We have now removed the users Exchange Online license as we want them to use their on-prem mailbox until we are ready to migrate their mailbox to the cloud.

Trying to remove the mailbox in O365 Powershell I get the following:

Remove-Mailbox -Identity John.Smith
'Windows LiveID Agent' : Unable to perform the save operation.  'John Smith' is not within a valid server write scope.

Disable-Mailbox -Identity 'John Smith'
Exchange can't disable the mailbox "John Smith" because it is on In-Place hold.

However, the mailbox doesn't appear to be on In-Place hold, as when I run the following command:

Get-Mailbox "John Smith" | fl compl*,delay*,inplace*

The following is returned:

ComplianceTagHoldApplied : False
DelayHoldApplied         : False
DelayReleaseHoldApplied  : False
InPlaceHolds             : {}

I have also tried the following:

Disable-Mailbox -Identity 'John Smith' -IgnoreLegalHold -PermanentlyDisable

But then I get:

Cannot Disable-Mailbox for 'John Smith' because this user has a valid license.

Please help!
Hi Experts,

What's the best practice of moving an on-premises, non-mail enabled public folder contacts and calendars to O365?
This will be a hybrid migration and we'd like to decommission the PFs as a part of the project. We're aware that they'd be accessible for online users during the hybrid, but that's not an option here.

Is shared mailbox for each PF a way to go or?
What's the easiest way to migrate?

Thank you

This is my situation.

- I have everything from Exchange 2010 (mailboxes, Public folder) move the O365.
- Remove-HybridConfiguration is ran (Is optional according to MS but we remove it)
- Because the objects sources are in on-premise AD we use Azure AD Connect to sync objects to O365
- Keep just 2 Exchange 2016 without mailboxes for management purpose only

Now , I'm just curious.

If " Remove-HybridConfiguration " is optional why don't we just do it. What this cmd does exactly? What AD attributes are removed after running that cmd?
I am trying to find out how to add a shared mailbox to an android phone.  I have Office 365 on my phone but I don't get the option to add a shared mailbox when I click on add account.

Hi Expert

We have in our environment exchange server 2016 with an enterprise license

Plus we have CLAs standard CALs

Now I want to enable the archiving and I got to know that this need enterprise CALs

So because I don’t have enough information about exchange licensing I would like to ask you the following

User mailbox                                    yes I know this need CAL

mail contacts                                   I don’t know if this need CAL or not please update me here

Distribution group                        as I know does not need CAL

Shared mailbox                             as I know does not need CAL

Room mailbox                               as I know does not need CAL

mail-enabled public folders        as I know does not need CAL

about shared mailbox as I got to know that if  I need to archive these type of recipient I have to buy enterprise for them but if don’t archive them just use them as it I don’t need to buy CLAs for shared mailboxes

please clarify this for me

Hi Experts,
