Several factors may lead to the issue when the Office 365 users don’t receive any confirmation after you successfully schedule a meeting or an appointment for an on-premises room mailbox in either Outlook client or Outlook Web App in Office 365. To solve it, please check the following settings:

  1. If your on-premises room mailboxes are not hosted on Exchange 2010 or 2013, please move the room mailboxes to Exchange server 2010/2013 mailbox server first.
  2. Check if the room mailboxes are set to automatically accept the booking requests.
  3. Also, once the room mailboxes are hosted on Exchange server 2010/2013 mailbox server, please set the ProcessExternalMeetingMessages parameter to True by running the following cmdlet on the on-premises Exchange server:

Set-CalendarProcessing ”<Room Name>”  –ProcessExternalMeetingMessages $True

——————————————————————

1. All on premise mailboxes are on Exchange 2010

2. All room mailboxes are set to automatically accept the booking requests

3. I checked the ProcessExternalMeetingMessages on all of the rooms and it was set to $false. I set them to true and then tried booking a room twice. I did not receive a response back either time. It was still set as Tentative. I’ll try again later to see if the problem takes some time to propagate through the system.

Exchange Server 2016 is here

On 2015-10-16, in Exchange 2016, Mailserver, by Mattias Jönsson
0

 

 

Recently, we announced availability of Exchange Server 2016 is here and available to download. Exchange 2016 builds on and improves features introduced in Exchange 2013, including Data Loss Prevention, Managed Availability, automatic recovery from storage failures, and the web-based Exchange admin center. What sets this version of Exchange apart from the past, is that it was forged in the cloud. This release brings the Exchange bits that already power millions of Office 365 mailboxes to your on-premises environment.

 

New Capabilities

 

[if !supportLists]·       [endif]Better collaboration: In Outlook 2016 or Outlook on the web, you can now attach a document as a link to SharePoint 2016 (currently in preview) or OneDrive for Business instead of a traditional attachment, providing the benefits of coauthoring and version control.

 

[if !supportLists]·       [endif]Improved Outlook web experience: New features include: Sweep, Pin, Undo, inline reply, a new single-line inbox view, improved HTML rendering, new themes, emojis, and more.

 

[if !supportLists]·       [endif]Search: A lightning-fast search architecture delivers more accurate and complete results. Outlook 2016 is optimized to use the power of the Exchange 2016 back end to help you find things faster, across old mail and new. Search also gets more intelligent with Search suggestions, People suggestions, search refiners, and the ability to search for events in your Calendar.

 

[if !supportLists]·       [endif]Greater extensibility:  An expanded Add-In model for Outlook desktop and Outlook on the web allows developers to build features right into the Outlook experience. Add-ins can now integrate with UI components in new ways.

 

[if !supportLists]·       [endif]eDiscovery: Exchange 2016 has a revamped eDiscovery pipeline that is significantly faster and more scalable. Reliability is improved due to a new search architecture that is asynchronous and distributes the work across multiple servers with better fault tolerance. You also have the ability to search, hold and export content from public folders.

 

[if !supportLists]·       [endif]Simplified architecture: Exchange 2016’s architecture reflects the way we deploy Exchange in Office 365 and is an evolution and refinement of Exchange 2013. A combined mailbox and client access server role makes it easier to plan and scale your on-premises and hybrid deployments. Coexistence with Exchange 2013 is simplified, and namespace planning is easier.

 

[if !supportLists]·       [endif]High availability: Automated repair improvements such as database divergence detection make Exchange easier than ever to run in a highly available way. Stability and performance enhancements from Office 365, many of which were so useful that we shipped them in Exchange 2013 Cumulative Updates, are also baked into the product.

 

That’s just quick list of highlights; we encourage you to get a full view of what’s new by reviewing the Exchange 2016 documentation on TechNet.

[if !supportLists]·       [endif]Planning and deployment

[if !supportLists]·       [endif]Short demo videos for features: Better Collaboration | Outlook on the Go | Architecture and Security/Compliance Improvements | Smarter Inbox

 

Exchange 2016 will follow the same servicing rhythm as Exchange 2013, with Cumulative Updates (CUs) released approximately every three months that contain bug fixes, product refinements, and selected new investments from Office 365. The CUs will include features such as search indexing from passive that we decided needed additional refinement or validation before arriving on-premises. The first CU will arrive in the first quarter of 2016.

 

For those of you eager to get hands on with Exchange 2016, you can start right away by getting the bits from the Microsoft download center to evaluate the fully-functional product for 180 days.

This one liner will list all users who have both SMTP email addresses (which appear in the Windows Email Address filed on their AD account), and a SIP address, but they don’t match. This is helpful in identifying users who may be contractors with their  own email address at their respective company, but have SIP addresses on your system. It’s also helpful in locating users who have typos in one of the two, or who are inadvertently assigned an incorrect SIP domain.

Get-CsAdUser | Where-Object {($_.WindowsEmailAddress -and $_.SipAddress) -and ($_.WindowsEmailAddress -ne ($_.SipAddress -replace "sip:",""))} | Select-Object DisplayName,WindowsEmailAddress,SIPAddress

This yields results such as

DisplayName       WindowsEmailAddress                    SIPAddress                
-----------       -------------------                    ----------                
Laurie Lederhouse llederhouse@fourthcoffee.com           sip:llederhouse@contoso.com
Eileen Alfini     eileena@fabrikam.com                   sip:ealfini@contoso.com   
Mike McGrath      mmcgrath@wingtiptoys.com               sip:mmcgrath@contoso.com  
Gavin Parmar      gparmar@contoso.com                    sip:goarmar@contoso.com

In this example, we see that the first three have different SMTP domains than SIP domains. In the last user, we see that the username part of the addresses is different, but the domains are the same. If you want to strip out the “sip:” from the SIPaddress column, we can add a little formatting and come up with

Get-CsAdUser | Where-Object {($_.WindowsEmailAddress -and $_.SipAddress) -and ($_.WindowsEmailAddress -ne ($_.SipAddress -replace "sip:",""))} | Select-Object displayname,windowsemailaddress,@{Expression={$_.sipaddress -replace "sip:"};label="SipAddress"}

This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool.

Problem:
Site folder server deleted
The site-wide public folder database for administrative group ‘Exchange Administrative Group (FYDIBOHF23SPDLT)’ has been deleted. Current public folder store: ‘CN=Public Folder\0ADEL:7b0fc218-05b2-4eae-9660-bbdd01f7e395,CN=Deleted Objects,CN=Configuration,DC=uw,DC=lu,DC=se’.

Solution:
http://technet.microsoft.com/en-us/library/aa996485(EXCHG.80).aspx

The siteFolderServer attribute represents the Distinguished Name (DN) of the Public Folder store that is responsible for hosting the site folders (normally the first server in the site or administrative group).

By default, the Site Folder Server is the first server that is installed in the administrative group. The public folder store on this server is the default location of the free/busy folders and offline address book folders for the administrative group. If you remove or decommission this server without replicating these folders to another server and designating that server as the offline address book server, Microsoft Office Outlook® 2003 users will see problems with the offline address book and with free/busy data.

Aa996485.Caution(en-us,EXCHG.80).gif Caution:
If you incorrectly modify the attributes of Active Directory objects when you use Active Directory Service Interfaces (ADSI) Edit, the LDP (ldp.exe) tool, or another Lightweight Directory Access Protocol (LDAP) version 3 client, you may cause serious problems. These problems may require that you reinstall Microsoft Windows Server™ 2003, Exchange Server 2003, or both. Modify Active Directory object attributes at your own risk.

To correct this error

  1. Open an Active Directory editor, such as ADSI Edit.
  2. Locate the public folder information store that you want to designate as the Site Folder Server. For Exchange Server 2000 through Exchange Server 2007, expand the following nodes in the Configuration container:
    CN=Configuration,DC=<DomainName>,DC=com, CN=Services, CN=Microsoft Exchange, CN=<OrganizationName>, CN=Administrative Groups, CN=<AdministrativeGroupName> CN=Servers, CN=<ServerName>, CN=InformationStore, CN=<StorageGroupName>
    For Exchange Server 2010, expand the following nodes in the Configuration container:
    CN=Configuration,DC=<DomainName>,DC=com, CN=Services, CN=Microsoft Exchange, CN=<OrganizationName>, CN=Administrative Groups, CN=Exchange Administrative Group (FYDIBOHF23SPDLT), CN=Databases
  3. In the right pane, right-click CN=<PublicFolderStoreName>, and then click Properties.
  4. In the Attributes field, scroll down and select the distinguishedName attribute.
  5. Click Edit, and then copy the entire attribute to the Clipboard.
  6. Expand the Configuration container, and then expand CN=Configuration,CN=<DomainName>,CN=com, CN=Services, CN=Microsoft Exchange, CN=<OrganizationName>, CN=Administrative Groups
  7. Right-click the administrative group you want to modify, and then click Properties.
  8. In the Attributes field, scroll down and select the siteFolderServer attribute.
  9. Click Edit, and then paste the value for the distinguishedName attribute into the Value field.
  10. Double-check the contents of the Value field to ensure the paste was performed correctly, and then click OK to save the change.
  11. Click OK to close the Administrative Group properties.
  12. Exit the Active Directory editor and restart the Microsoft Exchange Server Information Store service on all Exchange Server computers in the site for the change to take effect.

For more information about re-creating system folders and resetting the Site
Folder Server, see the following Microsoft Knowledge Base articles:

Microsoft announced this week that starting in summer 2011, IT engineers and consultants all over the world will have an opportunity to earn MCM status on Microsoft Exchange Server 2010 by passing the required exams at one of many international testing centers. This makes the on-site training at Redmond optional. See the following link for details:

http://www.microsoft.com/learning/en/us/certification/master-exchange-path.aspx

If you you want to learn even more about the MCM, you can read all about it here here. If you’re thinking about applying for the MCM program take a look at Neil Johnson’s MCM survivors guide and Brent Ozar’s blog series on the SQL MCM. Neil goes into great detail about the Exchange MCM, and Brent’s coverage of the SQL MCM is an interesting read (even for us Exchange guys). You’ll also want to keep an eye on The Master Blog for news and updates. Good luck!

Microsoft has recently created a great video highlighting the training experience you can expect when attending the Exchange MCM program. Watch the clip below to hear from MCM instructors and attendees as they discuss the program:
