Exchange 2010 – Change the language of folder names in Outlook

Posted by robd on July 19, 2016
exchange 2010, powershell / No Comments

So We had a shared mailbox that was originally opened in Finland and as such the inbox was named postilaatikkoon and sent items was named Lähetetyt.

So I thought I’d jump into OWA and change the language there, well it turns out that has nothing to do with Folder names.

So after some research I found I could use:

Outlook.exe /resetFolderNames

But the mailbox is shared so doesn’t have a enabled user to logon with so I found this Exchange PowerShell command:

set-MailboxRegionalConfiguration -id "Mailbox Name" -LocalizeDefaultFolderName:$true -Language en-GB

Job done.

Skype presence information not visible in Outlook

Posted by robd on April 09, 2016
exchange 2010, Outlook 2010 / 8 Comments


When you install Microsoft Skype on a Windows-based computer that has Microsoft Lync installed, you experience one or more of the following issues:

Microsoft Outlook does not display presence information.
The Microsoft SharePoint client does not display presence information.
Other Microsoft Office applications that support presence features do not display presence information

This behavior may occur if the value of the DefaultIMApp registry entry in the following registry key is incorrect:
HKEY_CURRENT_USER\Software\IM Providers

Note The DefaultIMApp registry entry specifies which IM application provides IM and presence information in Office applications. When you install the Lync 2010 client together with Microsoft Office, the value of the DefaultIMApp registry entry is updated to “Communicator.”  Or, if you install the Lync 2013 client together with Microsoft Office, the value of the DefaultIMApp registry entry is updated to “Lync.”
To work around this issue, follow the steps that are appropriate for the version of Windows that you are running.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

Windows XP, Windows Vista, or Windows 7

Exit the Skype client and all Office applications.
Click Start, click Run, type regedit.exe, and then click OK.
Locate the following registry entry:
HKEY_CURRENT_USER\Software\IM Providers\DefaultIMApp registry value
Right-click DefaultIMApp, and then click Modify.
Type Skype in the Value data box, and then click OK.
Exit Registry Editor, and then restart  the Skype client and the Office applications.

Windows 8

On the Start screen, click the Search tile.
Type regedit in the Search window and then double-click regedit.exe.
Locate the following registry entry:
HKEY_CURRENT_USER\Software\IM Providers\DefaultIMApp registry value
Right-click DefaultIMApp, and then click Modify.
Type Skype in the Value data box, and then click OK.
Exit Registry Editor, and then restart  the Skype client and the Office applications

Hope this helps

MAPI Connections to Exchange 2010

Posted by robd on August 19, 2013
exchange 2010, Office 2010, powershell / 5 Comments

So had a bunch of errors on my Exchange 2010 server today, namely:

Event ID 9646 MSExchangeIS

Mapi session "cd83bc42-1bff-459e-9db2-558cc68478b9" exceeded the maximum of 500 objects of type "objtFolder".

The error doesn’t give much away but basically what its saying is:

A user with GUID “ccd83bc42-1bff-459e-9db2-558cc68478b9” has more than 500 open folders in a single session, because exchange only allows 500 open folder connections (for a cached mailed) at a time its going to screw with the user and in our case not automatically update the users folders in Outlook 2010.  Please note this is different from open MAPI connections to the mailbox.

Note this has been edited with help from Mark Daley who stated:

the objtfolder is an ‘Open Item Limit’ ie the limit of the number of folders that are being opened in a single session, not the number of connections being made to the mailbox which is a session limit See (http://technet.microsoft.com/en-us/library/ff477612(v=exchg.141).aspx). This limit is the total for the session so if a user has 250 folders in their own mailbox and say 300 in a shared mailbox then the limit will be breached. The other thing that should be explained in that this is only likely to occur when the mailboxes are cached (shared and non-shared) as it is the consequence of caching that is causing the limit to be breached because each folder is opened / counted during the mailbox sync process. Therefore turning off caching mode for either the primary mailbox or just the shared mailbox is another fix for this issue.


You may be wondering how a user could have more than 500 connections, well in our case the user had two mailboxes attached to their own mailbox and all the folders (inbox, outbox etc) together added up to more than 500 folders.

You can scan a mailbox with Power Shell to determine the number of folders:

Get-MailboxFolderStatistics USER1@BohemianGrove.co.uk | Sort-Object ItemsInFolder -Descending | ft Name, FolderPath > C:\temp\countFolders.csv

So lets say you see the errors on your Exchange 2010 server but don’t know who’s having the issue, you find Users MAPI GUID’s by running the following Power Shell command:

get-mailbox -Resultsize Unlimited | ft Name,ExchangeGuid -AutoSize > c:\temp\msExchMailboxGuid.txt

Once you know who the user is what can you do, well there’s four options in my mind:

1) Tell the user to re-organise the folder structure,

2) Remove some of the extra Mailboxes from a users mail profile if possible (you could add a extra profiles to Outlook, making Outlook prompt on start up),

3) Do not cache the mailbox in Outlook or simply do not cache the additional mailbox in Outlook.

4) Change Exchange 2010 to allow more than 500 folder to be open at a single time for cached mailboxes!


To proceed with 4) you’d need to do the below but be warned if large quantities of users connected with plus of 500 folders your server performance will suffer drastically:

Log onto all your mailbox servers and create the following registry key:

  1. Click Start, click Run, type regedit, and then click OK.
  2. Expand the following registry subkey:
  3. Right-click ParametersSystem, point to New, and then click Key.
  4. Type MaxObjsPerMapiSession, and then press ENTER to name the new sub key.
  5. Right-click MaxObjsPerMapiSession, click New, and then click DWORD Value.
  6. Enter the object type as specified in the event description, and then press ENTER.
  7. Right-click the object type that you entered, and then click Modify.
  8. In the Value data box, type the number of objects to which you want to limit this entry, and then click OK.

Auto Assign Colour to Outlook Calendar

Posted by robd on May 09, 2013
Calendar, Office 2010, Outlook 2010 / No Comments

Did you know you can automatically assign calendar entries colours (notice how colours is spelt the correct British way) and categories.

I.e. say you have set a meeting called “Project Bob” and that meeting and any future meeting with words “Project” and “Bob” in to be set a specific colour in your calendar, well here’s how:

Open your Outlook Calendar

Outlook 1

Click the View Menu item

Outlook 2

Click the “View Settings” button under Current View

Outlook 3

Click the “Conditional Formatting” button

Outlook 4

Click the “Add” button to create a new rule for auto-colouring appointments

Outlook 5

Enter the name of the rule in the “Name:” text box e.g. Project Bob

Select a colour in the “Colour:” drop down list box (I like green)

Click the “Condition…” button to identify the conditions under which this colour should be applied

Outlook 6

Select the “Appointments and Meetings” tab and enter a keyword into the “Search for the word(s):” text box to look for a word in the Subject field

Click OK to all screens,

You should see the changes straight away.

Scan PST Office 2010

Posted by robd on May 08, 2013
Outlook 2010 / No Comments

Just a quick post on how to scan PST (or OST’s) files if they become corrupt or wont open:

The tool I’ll use is ScanPST.exe which is installed when you install Office 2010.

ScanPST.exe is located below with Office 2010:

C:\Program Files (x86)\Microsoft Office\Office14\SCANPST.EXE

Open the tool and click Browse and find the PST you want to scan:


Then click Start, if the PST is large this can take a while:


If the PST can be fixed ScanPST will prompt you to backup it up before it attempts to fix it:


Click Repair.


That’s it done.  Try and open the PST or OST again from Outlook.

If the above didn’t work and I wouldnt be surprised if it doesn’t you could try Stella Phoenix PST report tool which is better and generally works!!

The Mysteries of VMware Zimbra

Posted by robd on May 04, 2013
Office 2010, VMware Zimbra / No Comments

I had a replace a PC for a user today who’s email was hosted externally.

So after I replaced the PC I came to setup Outlook, checked the old PC and saw the following setup:


What on earth is

iC Exchange I think to myself!! Check the config:


What are these settings, I’ve never seen the like before!!!

So what do I do?!?  Well the Server must be accessible from the internet so after a bit of playing the server was accessible from http://mail.EXCHAGESERVER.co.uk and using some provided credentials I could logon!!

Once I logged on I realised I wasn’t looking at Exchange I was look at VMware Zimbra!!  I’ve never heard of this and watching the promotional video they said Exchange was legacy so I immediately decided they were stupid!!

Well reading about I found I needed a Outlook connector which I could download from any server running VMware Zimbra!!

So went to:  http://mail.EXCHAGESERVER.co.uk/Downloads/

Downloaded the client, installed and used some provided credentials!! BAM done.
