I am attempting to update my Exchange 2013 server that is currently on CU7 to CU22.  When I attempt to install CU22, it prompts me for the CU7 installer file which I no longer have.  It used to be available as a download here: https://support.microsoft.com/en-us/help/2986485/cumulative-update-7-for-exchange-server-2013

But has since been removed.  I cannot proceed with this upgrade without this file, which I have been told is only available from Microsoft.  

Thank you,

Jonathan

I have tried to redownload the CU22, Its extract with no problem.

The server had not been patched for a long time, so I When durring the process of updating windows to Current update, and then update to .net 472 before trying til install first the CU21 - which failed with the same error as, the CU22 :-(

My guess it's its something local on the server causing the issue, since its both CU 21 and CU22 which fails with ApaAgentPerfCounters.h. 

I have don a procmon off the installation, and the MSI have access to the \ApaAgentPerfCounters.h file.What todo ??

When I install an Exchange CU, my user account gets added with Full Control access to CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=example,DC=com.

This causes a problem for me with the automapping feature.  When I add full control access of a mailbox, the mailbox does get auto-mapped in Outlook for me.  But when I remove full control access, the mailbox remains in Outlook and a deny permission gets set on the mailbox.  I end up having a mailbox in my Outlook that I cannot open.

So, to resolve, I have to do two things.

1. Open ADSI, navigate to CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=example,DC=com, open the security properties, and remove my account.

2. Run the following PowerShell commands:

Get-OrganizationConfig | Remove-ADPermission -user "USER.NAME" -ExtendedRights Send-As -deny
Get-OrganizationConfig | Remove-ADPermission -user "USER.NAME" -ExtendedRights Receive-As -deny

Is there any way to stop the CU installer from adding my account with Full Control permission to the Microsoft Exchange service configuration OU in the AD?

Issue

When we activate Databases from ( Exchange 2013 SP1 Mailbox server to Exchange 2013CU21 Mailbox Server ) in Production  , User's outlook ( outlook 2010 and 2016) connectivity are showing disconnected . Client are using Mapi over http ( not rpc over https) internally.
Tested by creating new profile but getting same issue and not able to connect to exchange server as well .Once we activated back Databases from Exchange 2013CU21 to Exchange 2013SP1 in Production , all were connected back to normal.

We have confirmed all Exchange service  are running and setting are same with other Exchange 2013 mailbox Server SP1  after upgraded to CU21 on Mailboxes Servers.

Hi, 

I installed exchange 2013. The installation went bad I had to uninstall it manually from ADSI edit, then deleted the VM. I installed exchange 2013 once again. I log into ecp, I find under recipients the old mailboxes created with the old exchange server. when I try to delete them or move them, the following error shows: 

The object domain/Users/someuser has been corrupted, and it's in an inconsistent state. The following validation errors happened:
Database is mandatory on UserMailbox.

digging around on the net, I followed this link: http://support.microsoft.com/kb/2702446?wa=wsignin1.0

but I noticed that my homeMDB is not set. 

also following this link: http://technet.microsoft.com/en-us/library/dd535374(EXCHG.80).aspx

I noticed that I dont have anything under this location in adsi edit, while it states that there are some child objects

config...\config...domain\services\microsoft exchange\org-name\administrative groups\ex...admin..groups id\servers\mailbox\informationstore

Should I have ran setup /prepschema and setup /prepad, i didn't because in MS documentation it stated that if the account is a member of enterprise admin and schema admins the schema and AD and Domain preparation would be done by the wizard.

If its partially prepared, can I run them commands again without causing problems?

I can create new users just fine, all I want is to delete these recipients and create a new working ones. also I want to know is my exchange setup right, because I don't want to face major problems when we go live.

its been 3 weeks hitting my head against the wall, help please.

We have about 500 users coming from a notes env.  to our env of exchange 2010.   They want to bring their emaisl with them.   We may be provided by NSF files by their mail admin and then we use a third party tool to convert to pst.  Question .. what is the best approach, what will happen to recurring appointments, tasks,  encrypted items? Their admin will/may config mail forwarding at his end pointed  to their mbxs on exchange server at our end. Not sure what strategy he/we adapt.  How would you do or done this kinda migration? Whats were the lessons learnt and what shud we consider.  Much appreciated- tnx! there will be none or have no relationship or trust of any kind between these 2 orgs.

have an SBS 2011 that i can't get exchange sp3 to apply.

This server may not be in the best of shape, but we are working that out as we find out more about it.

anyway issue currently is that when applying exchange sp3 it fails with the error below

have stopped windows SBS management service also have run it with the /m:RecoverServer. switch

still fails with the same error. most of my googling so far hasn't yielded any results.

can anyone advise on what to do next

thanks in advance

Hi

Exchange Server 2013 Database not showing in ECP and I cannot see whether they are mounted or not.Kindly help.

Regards Gift

Looking for some advice on how or if I should do this. I currently have an Exchange 2013 server functioning normally on a 2008R2 VM. I am wanting to get the jump on phasing out all my 2008R2 servers to 2012R2 or 2016.

I have experience installing Exchange 2013 on 2012R2 in my home environment and it runs very smoothly (In one of my IT Classes I was told that EXCH2013 was actually designed to run on 2012) Does anyone have experience running EXCH2013 on 2016 Server? Does it run well on that newer OS?

If I decide to install a new EXCH2013 server in my work environment, (on 2012R2 or 2016) Will I have to create a new database and migrate all the email boxes over (like when we upgraded from EXCH2010 to 2013) , or can I simply mount the old database in the new server?

I believe if I do this, the server will have to be treated like a completely new fresh installation and the server must actually have a different name as well.

Thank you

HI

I need to create a hybrid environment for my exchange org, have read a bunch of "howto's" and they go about this a lot off different ways so I need to some more info:

My setup is as for now:

I run Exchange 2013 (cu21) onprem

I have a O365 tennant and Azure AD Connect functioning for passwords (I noticed there was an Exchange option there also)

The goal is to go "Full hybrid" and stay like that.

But I am thinking of upgrading to exchange onprem to 2019, so the question is how would you go about this?

• Upgrade Exchange onprem first?
• Go hybrid first?

Also can I make Exchange online the primary mx while using exchange onprem  like smarthost for all outgoing mail?

And I was thinking og using this article as guidelines for this work.

Will I have to change Azure AD connect's options?

Regards Gudjon

HI, we have a very random (once in a month if that issue) random users onsite / remote using OUtlook 2016 desktop client (Windows 7 or Windows 10) upon logging into Windows, they launch Outlook, and right away they get the credential pop up window.  We have cleared the credential manager, even setup a brand new PC for some users, and intermittently at random, only at initial logging into Outlook do they get this credential manager to enter creds for Outlook.  Once they click "cancel" and at the bottom corner of OUtlook, they just double click "Enter Password" and Outlook connects automatically...no more issues.

It is hit and miss, the issue cannot be replicated.

The issue started 2 years ago when we were on Exchange 2010, and then migrated to Exchange 2013, the issue still exists randomly, it has recently affected some senior management so the issue is pressing now to get resolved.

I ran Health Check all is showing Green 

ran Exchange RCA, 1 thing comes out, 

attempting to resolve the hostname autodiscover_domain_ca in DNS

We have Exchange 2007 and trying to get hybrid exchange with Office365 online. We have setup Exchange 2013 but when trying to access EAC from the server it is giving below error,

Outlook  500  Unexpected Error :(   An error occurred and your request couldn't be completed. Please try again.

Can anyone help to provide what could be the reason? what needs to be configure before accessing EAC from on-premise server?

I am trying to access by https://<FQDN Server Name>/ecp/?ExchClientVer=15

Please help!

I have an Exchange 2013 installation started with SP1 that I have kept updated installing the Cumulative Updates when they were released.

I have observed that after each CU installation the C: free space (Exchange is installed on C:) was less then before. So I searched in the Exchange install directory and I have found a lot of sub-directories named with an Exchange build number, expecially under the ClientAccess install dir and the OWA subdir.

For instance, under C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa I have many folders named "15.0.995.28", "15.0.995.32", "15.0.1044.21", "15.0.1044.27", "15.0.1076.2", "15.0.1076.10".

The C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa\prem directory has the same subfolders and is consuming a lot of disk space.

As I could understand, the CU setup should remove the older files but it seems that it does not and keeps older version in these directories. I have tried installing a fresh Exchange 2013 CU8 on a new server and these directories are not present.

The question is: is that correct?

And: can I safely delete the older versions folders?

Thanks

I'm in the process of migrating from E2013 to E2016. I've tried to start my mailbox moves, but any user I migrate just stays in a "syncing" state. I've left batches running for days and it never changes. The users are only test accounts, so there really is almost no data. I am also only doing 1 user at a time until it is successful.

On the E2016 event log, it shows the migration cmdlet was started successfully. No other events after that. On the E2013, no messages there either.

Running the Get-MoveRequest -BatchName "Pilot" | Get-MoveRequestStatistics cmdlet yields nothing. It just returns to a prompt with no output.

I've had to kill the batches forcefully as deleting them also just hangs in a state of deleting.

I've tried restarting a Mailbox Replication as others have suggested and that doesn't do anything either.

Any ideas?
