Help with a messy Office 365 migration and company split

$

I need help with a messy Office 365 migration and company split!

We are two separate companies that share a network and server infrastructure and are parting ways in the next few months and I am trying to separate out our organisations into two separate Office 365 tenants.

We have two separate domain names for our emails (e.g. Company_1.com andCompany_2.com) which are both running on the same exchange server (Exchange 2010).

I have separated out all users in our Active Directory into two Organizational Units (Company1 andCompany2).

I have installed Azure Active Directory Sync on the Exchange server and synced theCompany1 OU with the Company_1 Office 365 tenant. I have also installed a separate instance of Azure AD Sync on the Domain Controller server and synced theCompany2 OU with the Company_2 Office 365 tenant. This all seems to work as each O365 tenant now has all the correct users in.

I have also performed a hybrid migration on the exchange server for Company_1 and have successfully synced my mailbox (I work for company 1) onto O365 and this all seems to be working fine.

Company_2 have now said they are happy to have a cutover migration as their situation for the next year will be such that they may be server-less and so are happy to have all their emails in the cloud without a hybrid migration.Company_1 would like to keep a hybrid migration.

I am now trying to migrate users from Company_2 into their O365 tenant by manually adding the SMTP@company_1.mail.onmicrosoft.com addresses into their users and then performing a migration to their tenant (as the exchange server is still setup as a hybrid forCompany_1).

- Will I be able to do this and then just point their mail DNS to the O365 DNS with no problems?
- And without decommissioning the exchange server?
- Is there a better way to do this?

(Company_1 will still be using the exchange server for the time being and will then be migrating to a new upgraded exchange server in a hybrid environment.)

Microsoft Exchange container deleted.

Took over a site and previous admin deleted old exchange server and removed the  Microsoft Exchange services container from AD. 

The AD container

CN=org,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=domain,DC=local has been deleted.

All Mailbox databases have been deleted because the old exchange server was deleted / removed from environment. 

Exchange management console(installed on another server) and shell still manage to open and seem to think that there are mailboxes .(return values for 'get-mailbox')

The homeMTA objects of users is pointing to a deleted object

msExchHomeServer is also pointing to a server that was deleted

I am in the process of getting MS involved as well but looking for suggestions. 

I have the DC and the server with mgmt tools installed up in a lab and I am going to test installing exchange 2013 to see if that even works. Even if i get exchange 2013 installed I am worried what is going to happen when I enable hybrid. I feel as though I will be needing to manually modify AD attributes for each user. 

Allowing certain attachments - Exch 2010 / Outlook 2007

$
0
0

By default, it seems that Exchange 2010 blocks XML attachments which is reasonable to expect. However, we have a client sends us regular emails with XML attachments and we need to retrieve these. I have been able to allow xml attachments to retrieved through OWA but they are still being blocked in Outlook.

  1. What is the method to globally allow a particular attachment?
  2. Is there a way to allow an individual Exchange Mailbox to retrieve certain attachments while remaining blocked in the others?
  3. Is there a method to allow these attachments from a particular send/address email address?

Thanks in advance!

Help migrating or merging Office 365 Business to Education

$
0
0
We are both a charity and a college and I originally setup our Office 365 account as a nonprofit account and we are using Office 365 Nonprofit Business Premium licences as we had no need at the time to have our students on the same system. Now we would like to provide all our students with email addresses and O365 accounts but I have realised that we should have setup originally as an Office 365 educational account such as A1 or A3 licences so that we can use Microsoft Teams for Education which offers additional benefits for students and tutors that Teams for Business doesn't. Microsoft Support have stated that they cannot convert a nonprofit tenant to an educational tenant and advised that I create a new edu tenant and have it verified as an educational establishment which I have now done meaning we have two tenants.

We are all currently using Tenant 1 which has been setup as CompanyName.co.uk on a nonprofit account with Business Premium licences. I have also setupTenant 2 which is setup as CompanyName.net on an educational account withA1 licences. We still want to keep our original domain CompanyName.co.uk

I am trying to work out the best way to move all our current users including their email accounts, OneDrive, Microsoft Teams, Sharepoint sites etc. to the second edu tenant and then transfer the domain and DNS to tenant 2? Or is there a way to keep both tenants and enable it so that staff in tenant 1 are able to login to tenant 2 with their tenant 1 addresses? Or combine the tenants so that in the end I am left with just the educational O365 tenant (Tenant 2) but with the original domainComanyName.co.uk?

Any help would be greatly appreciated!

What files can be removed when removing a database

$
0
0

Hello All,

I have unmounted and removed an Exchange database from our Exchange 2010 organization. I also removed the edb file as noted in the pop-up massage.

There are a few log files that have a date-time stamp that is before the time I unmounted the database. There is also a folder named CatalogData followed by a long alphanumeric string.

Can these files or folders be deleted as well? They don't consume hardly any disk space so there isn't a real benefit to removing them. However, I would like to clean things up as much as possible.

Thanks for any thought on this.

Performance issues with Exchange 2013 DAG since applying (KB4536988)

$

0

Hi all,

Currently running Exchange 2013 - 3 node DAG (2 on site - 1 dr site). 

Since updating to applying the following update we have seen a marked drop in performance from the servers and users are reporting that their overall experience has dropped considerably. 

Security Update For Exchange Server 2013 Cumulative Update 23 (KB4536988)

Servers were originally on CU15 upgraded to CU21 pre December, no issues. Completed the step upgrade between CU21 and .net to get to the correct levels - .net is currently 4.7.2

Once the update was completed we did have the ECP / OWA issues listed in the below article, applied the fixes and no problems there, just the bad performance

https://borncity.com/win/2020/02/15/exchange-server-2013-mail-issues-after-update/

Examples include Outlook dropping connecting, taking increasing time to access folders and mailboxes 

Two servers @ primary site with DAG, majority of users are connecting in through Citrix with mailboxes in online mode. 

Checking the CAS load its appears to only be reporting that a since server has any connections.

Any advise would be appreciated.

Hi experts

i am completely new to exchange 2010 and new to company, i am using exchange 2010 hybrid environment, i have worked earlier on exchange 2016. I dont have much idea about exchange 2010 as the architecture is different. we hardly have 10 mailboxes in exchange 2010 onprem and we basically create mailboxes in exchange onprem and
migrate it to cloud. currently we have 15000 users in cloud.

When i use the below syntax i can see by the naming convention there are 6 CAS servers and 3 DAG servers,
CAS01 to CAS06-->Hub transport and client Access roles are installed , DAG01 to DAG03-Mailbox server role is installed.
Get-ExchangeServer | fl name,edition,admindisplayversion

Using the below syntax i can see i am using Update Rollup 21 for Exchange Server 2010 SP3
[PS] C:\Windows\system32>Get-Command ExSetup | ForEach {$_.FileVersionInfo}

1. Current latest rollup is 30 as per the below article, do i need to first update the rollup on CAS servers or DAG servers
https://docs.microsoft.com/en-us/exchange/new-features/build-numbers-and-release-dates?view=exchserver-2019

2.What is upgrade path to exchange 2016 or exchange 2019.

New-MailboxExportRequest remains "queued" at 0%

$

Greetings, my mailbox exports are going into "queued" status, and remain at 0% complete even after many hours.

This is occurring on every mailbox which we've tried to export (about a dozen so far), and they are scattered across all 16 of our DBs.

It was working fine in December, and we've been trying for months to find out why it stopped working.

The environment is 2x CAS/HT front-ended by an F5 appliance, and a two-member DAG with a FSW.  All servers are at Exchange 2010 SP3 RU5.

This is my command line:

New-MailboxExportRequest -verbose -Mailbox '<<mailboxname>>' -Name '<<exporttaskname>>' -BadItemLimit 999 -AcceptLargeDataLoss -ExcludeDumpster -FilePath '\\<<fqdn>>\Mailbox-Exports\<<filename>>.pst'

Which results in this ---

[PS] C:\>Get-MailboxExportRequest | Get-MailboxExportRequestStatistics Name Status SourceAlias PercentComplete ---- ------ ----------- --------------- <<mailboxname>> Queued <<exporttaskname>> 0

...and the value in the PercentComplete does not increment, even when hours have passed.

MAPI is enabled on the mailbox.  All of the DBs are mounted or healthy.  We've rebooted all of the servers. We've restarted the replication service on all the servers. We've made sure the "MRSConfiguration" settings in MSExchangeMailboxReplication.exe.config are at their defaults.  There's nothing odd in the system or application logs.

Here are the results of a status check ...

Hi,

On My HUB server, I keep on getting Edge Sync Event 1024.

Failed to connect to the Edge Transport server ADAM instance with exception The LDAP server is unavailable..  This could be caused by a failure to resolve the Edge Transport server name XXXXXXXXXX in DNS, a failure trying to connect to port 50636 on XXXXXXXX, network connectivity issues, an invalid certificate, or an expired subscription.  Verify your network and server configuration.

But , Edge sync is running fine, when I ran test-edgesynchronization

Failed to send via smtp from Hesk

Hi everyone, I have a problem when I configure the sending of mail by a PHP application installed on IIS, it should use TLS authentication via SMTP to send mail externally to the network where the Exchange server is present.

Currently, SMTP forwarding works only within the domain of the Exchange 2010 server (On windows server 2008 r2), setting the application on port 25 and without authentication.

The reception of emails also works from the outside, on port 993, with the ssl protocol.

The application is Hesk (an open source ticket system), installed on IIS on a Windows Server 2016 server in the same Exchange domain.

The error I get when configuring TLS and authentication is as follows:

Hi guys,

Our Exchange server just started getting pegged every night from exactly 6:30pm until 7:30am.  When I look at the processes that are pegging it, it looks pretty normal.  The biggest difference is store.exe is higher(44%) and there are multiple w3wp.exe processes that are higher(w3wp - ExchangeServiceAppPool) - 26% and w3wp.exe(ExchangeSyncAppPool) - 20%.  Does anyone have any ideas of things I can check that might be kicking off precisely at 6:30pm?(not because of backups)

Online mode and OST file - Exhange server 2010 and Outlook 2010

$
0

Hello everyone,

This is in Exchange server 2010 and Outlook 2010 environment.

I am troubleshooting an issue with the email/outlook being slow. 

I found out that outlook uses OST file and in Online mode. I know for a fact that when cache mode is enabled in outlook, you can still use it while offline, open previous email messages, create emails, things like that.

What I don't understand is why the OST file gets bigger? it is now almost at the maximum size limit (49.7GB). I know that there is way in the registry to change the maximum size limit but I don't know if it's worth doing, I don't even know if the Online mode has to do with the OST file.  

HEre are my questions.

What is the relation of Online mode to the OST local file? What is stored in the OST file? Does it store offline email messages even it does not use cached mode? 

Also, is there way in EMC that I could run to check if others clients are using online mode?
