Limit permission on calendar

Hello,

I create  ressources (equipments) mailboxes on my server. And I want to restrict the reservation of this equipment. I mean one or two groups (AD security groups)  should had the permission to book this equipment.

I use this commande: 

ADD-MailboxFolderPermission -Identity My-equipment:\calendar -User 'security_group' -AccessRights 'owner'

Set-MailboxFolderPermission -Identity My-equipment:\calendar -User 'Default' -AccessRights 'None' or 'Reviwer'

When I verify the permission:  Get-MailboxFolderPermission -Identity My-equipment:\calendar

FolderName           User                 AccessRights
----------           ----                 ------------
Calendar             Par défaut           {None}
Calendar             Anonyme              {None}
Calendar             AD_User          {Reviewer}
Calendar             My_security_groupe     {Owner}

BUT, Everyone can book this equipment !! Is there any mistake ? How can I give the booking rights juste for one Ad Security group ??

Thanks

Updating Outlook 2010 Account Information box?

Until now, we've hosted one of our Health Center's email within our email domain, so their addresses appeared as: auser.healthclinic@tachc.org. Now, we're hosting them in our Exchange 2010 environment, but at their own domain, so their addresses will now appear as: andy.user@healthclinic.org (for example). 

They have hundreds of non-technical users and want to know if there's a way to update users' Outook so that the Account Information on the File Tab reflects their new email address. Also, on the Home Tab at the top of their Outlook folders. As I mentioned, they have hundreds of computers and don't have the man power to go and manually reset every one. Any help is apprciated!

Passive node in DAG killing global catalog

Hello,

we have environment with 2 servers in DAG (2013 latest updates).

2 Mailbox servers in DAG

2 CAS servers in NLB

Passive dag members are killing Global Catalogs with too much queries.

if i simply remove passive servers from network CPU drops from 100% to normal 0-10%, and active server is working normally. 

so i wonder, what may be the reason for passive server to be more agressive on LDAP servers?

Antivirus disabled, NSPI caching also configured, tried with any possible solution for now, and still can't kill that monster.
I even implemented new exchange, and its always the same- passive ones are just sending too much LDAP queries. 

Thanks,

Ivica

Can't Change User Passwords in Exchange 2013 Powershell or EAC

This is rather frustrating. I have been going back and forth with this for a while. We can't change the passwords for users.

I go in to the EAC, Permissions, Admin Roles, Organization Management, then try to add in the role for Reset Passwords. Go to save and I get the following.

You don't have access to create, change, or remove the "Reset Password-Organization Management" management role assignment. You must be assigned a delegating role assignment to the management role or its parent in the hierarchy without a scope restriction.

That's fine, so I do a bunch of research and everyone says the same things. Almost everyone cheers that this did the trick.

  • Launch Exchange Management shell.
  • Type Add-pssnapin microsoft* and hit enter.
  • Type Install-CannedRbacRoles and hit enter.
  • Type Install-CannedRbacRoleAssignments and hit enter.

Almost everyone cheers that this did the trick. Unfortunately as soon as I enter the Install-CannedRbacRoles in to the Exchange Shell I get the following.

Install-CannedRbacRole : The term 'Install-CannedRbacRole' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ Install-CannedRbacRole
+ ~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Install-CannedRbacRole:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException


There are a whopping 2 Google entries I found searching "The term 'Install-CannedRbacRole' is not recognized as the name of a cmdlet" No one has answered the question of where to go if the Install-CannedRbacRole is unable to be used. Everything is being entered in to the Exchange Shell from Admin accounts ran as Administrator. Any ideas what is going on here?

Using third party certificate on multiple servers

I work for a group of companies - one parent company and 4 separate companies that it owns.

They all have separate systems - different domains, etc. and are on physically separate sites. They are all fairly small companies and each has a single on-site Exchange server serving just that site/company.

All sites use Outlook Anywhere so require a third party certificate.

My question is can I use a single third party (SAN) certificate for all 4 Exchange servers or do I need separate certificates for each? 

Many thanks in advance for help with this :-)

Hi there,

We are facing performances issues when we receive multiple massive emails.

We have 65 000 student mailboxes and we often receive massive information email that have to be delivered to all the student's mailboxes. The underlying storage gets overloaded when we receive multiple of these emails at once.

I'm looking for informations about "Throttle concurrent connections based on messaging database health" described here : https://technet.microsoft.com/en-US/library/bb232205(v=exchg.150).aspx

I'm not quite sure about how this is supposed to work, and I found little informations about it.

What I'm looking for is throttle the transport/delivery of these emails based on storage latency. 

Any hints ?

Thanks

CU11 update broke my exchange server

Hello,

Was having trouble accessing our ecp and owa. One of the quick fixes was to make sure exchange was updated. I started the CU11 update and at 15 of 19 it crashed and an error keeps popping up at the same step even after a restart of the update. at this point EMC stopped working and certain  Exchange services would not start at all.

I've tried removing the update and even restoring but since it failed the update it was unsuccessful. Atleast 8 services are not starting, IMAP4, Transport, transport log search, Health manager, management service, Unified messaging call router, Diagnostics & Imap4 Backend. Manually starting them would come up with error 1053.

I'm thinkin I should just reinstall and recover the server but. I can't even uninstall from control panel since it would crash as soon as I click uninstall and since I have no access to EMC at all to disable all the mailboxes. it's just corrupted Any help would be greatly appreciated before I'm just forced to start all over again

Legacy 2010 hybrid config for retired servers causing new 2013 hybrid config to fail

January 28, 2016, 7:38 am
$

I piloted a migration to O365 a few years ago when my environment was mainly Exchange 2007.  I had to standup a couple 2010 CAS's to proxy the traffic.  We scrapped the pilot after testing, and of course there was no way to remove the config beyond ADSIEDIT.  

Fast forward to today with my environment all Exchange 2013, and I'm trying to standup a new hybrid configuration.  The Hybrid Configuration Wizard detects the old config and offers to upgrade it.  If I don't check "upgrade", I can't continue.  When it tries to upgrade the configuration, it tries to connect one of the old Exchange 2010 CAS servers that have been retired for over a year.  As far as I can tell, the MSExchCoexistenceServers and MSExchCoexistenceTransportServers attributes in the Hybrid Configuration portion of the schema are the only references to these servers left in Active Directory.  Exchange was gracefully removed, the servers were removed from AD, and they were powered off.  I tried adding a DNS A record to point that name to a new server.  I also tried changing the schema attributes to point to a new server.  Neither worked.

What are my options here?  I figure if worse comes to worse I can cross my fingers and run remove-hybridconfiguration (notes say to only do this with MS Support) or just blow away that part of the schema.  Neither are really too appealing to me. Thanks!

Dear friends,

I have a scenario. I have 2 data centers each hosting a CAS and a Mailbox server.

Data center 1:

CAS01 (Acting as witness)

MAIL01 (Primary)

Data center 2:

CAS02

MAIL02

Due to a previous experience (when data center 1 fails all dbs got dismounted until the data center become online) i have configured alternate witness server as CAS02 in the DAG. As of my knowledge,when data center 1 fails the primary mail server and the witness will fail and all the dbs got dismounted.

How can we restore this, i know that the command is 

Restore-DatabaseAvailabilityGroup -Identity DAG1 .........
Can you guys plse let me know the exact command to do a fail over/switching to the alternate witness server?

Thanks.

Arun

In-place archiving questions

February 1, 2016, 1:48 am
$

Hi all,

I'm currently testing Exchange 2013's capability of archiving user mailboxes however I've got a couple of scenario's I'm trying to resolve and using the built in archiving system may do what I need it to but I've ran into a few issues:

1. Large mailboxes.

2. In-place archives and overall OST file sizes.

1. We've got a few users & generic mailboxes with enormously large mailboxes, approx 25 - 35GB usage on the live mailbox. A few users have access to these large mailboxes either in a PA/Director capacity (e.g the PA's need to view the Directors large mailbox and put items in their calendars) and also from a departmental basis other users need to access a shared mailbox, again which is very large (approx 30gb).

I've created a policy on a test mailbox to move anything older than 1yr to the archive to help improve performance to reduce the "live" mailbox size but this leads me onto point 2:

OST sizes. I understand that the maximum limit for an OST file is 50gb (we run Office 2016 here) however in my testing it looks like enabling a user for in-place archiving won't help our PA's or users with access to shared mailboxes as when I enabled archiving on a shared mailbox in my tests, the in-place archive automatically gets mounted so I'm not really reducing the overall OST file size.

So my question is, is there a way NOT to mount the departments in-place archive? If we can do that, that will reduce the OST file size and resolve the 50GB limit for my user. If they need to view the in-place archive I can point them to use OWA and switch into it.

Dear all,

we are currently running Exchange Server 2010.

I often have a request from users to delete the email that they have accidentally sent out and failed to recall from specific mailboxes. may I know whether any command that I could run? Maybe it is best that we can delete based on subject name or maybe based on sender name within specific period of time.

Please advise.

Thanks.

Migration from 2007 to 2013.  Performed all the steps required per technet.microsoft.com/en-us/library/jj898581(v=exchg.150).aspx.  Exchange 2007 has been completely removed from the organization.  Still getting many of these errors although public folders are working perfectly (i.e. mail is flowing to the public folders without bounces or any issues at all).  Any thoughts on how to get these event log errors to stop?

Thanks,

Paul
