Exchange

Solved : Cannot display the folder.

I found out that opening very large mailboxes (several GB’s) using Outlook 2013 (32 bit) I ran into a not enough free memory problem :

After some troubleshooting I found out that there are 2 solutions. The first one is completely disable caching of the mailbox. But that was not a working solution for me, because sometimes I want to open my email without a working internet connection. This is the solution that worked for me :

Leave use cached exchange mode on, and clear (disable) the download shared folders and download public favorites.

I’ve never seen the error since!

Advanced administration Office 365

3

More and more companies start using Office 365 (including me:-)). The interface is simple and administration is fairly easily to use. But sometimes you wish you could do that little bit more, those things you could do when running Exchange 2013. I’ve got a surprise for you… you can!

Ok, let’s assume you are running Office 365 with one or more licenses. You probably now how to log on. Let’s go to https://portal.microsoft.com and use your credentials to logon :

image

After entering the credentials you see something like this :

image

Go to Outlook and you see you inbox. Ok, pay attention. You now see that your url has change to outlook.office365.com/owa/and something more. Let’s change everything after .com/ to /ecp. So you have the following url https://outlook.office365.com/ecp

SNAGHTML2bd5af9

And (when you are an administrator of your Office 365 account) you now see the following screen :

image

Wow! That looks familiar! You now have (almost) full control over your Office 365 account. (Which uses Exchange 2013 under the hood).

Now it’s possible to :

  • administrator advanced options
  • access to malware and quarantaine filters
  • track and trace emails
  • create and administrator public folders
  • configure archiving etc

More information soon in part 2

Review MigrationWiz

0

Because I’m doing more and more Office 365 migrations I was looking for a solution to automate this proces. I was looking for a tool that could automatically migrate mailboxen, contacts, public folders etc. Ofcourse using PST-files is one way to do it, but when you are migrating lots of data (Gb and/or users) this could take some time. I’ve heard the name BitTitan several times their product MigrationWiz seems to good to be true. I decided to ask them for a trial license to test the product.

MigrationWiz doesn’t require any special software, this because it’s all webbased. Just go to the website and login. After logging in you see the following :

image

First you have to create a connector. A connector is the link between your old en your new environment. Setting up a connector is an easy thing to do :

image

In the above picture you can any source configuration you are using, you can choose the same options in the target. So you can use MigrationWiz for the fallback scenario also.

You can also specify what to migrate :

image

Ofcourse you can migrate emails, but also calenders, contacts but also the rules(!) I particularly like that option because I created many rules to move incoming mails to their folders and their is no other easy way to export/import those.

After creating your first connector you can find it in the manage connector section :

image

In this view you can easily edit the connector, view statistics and see the mailboxes you are about to migrate.

After creating the connector you can add the mailboxes you wish to create. Their are several ways to do that. First you can manually add them :

image

You don’t have to have each user’s password. You can select one migration account which has access to all the exchange accounts.

Another way is to do a bulk import :

image

As you can see in the above screen, everything is fairly easily and their is little room for mistakes. It would be nice although if you could select the mailboxes from a list that MigrationWiz provides but that option isn’t (yet?) available.

After adding the mailbox(es) you can start the migration with the option buttons :

image

The first button is to start the migration, the second gives you the details, you can change the settings of delete the mailbox from MigrationWiz (not Exchange!)

After starting the migration you can see the progress in detail :

At this point you just have to wait for the mailboxes to complete. :-)

Other thing I think are worth mentioning :

Migration Skydrive / Google Drive data :

image

Migration Public Folders :

image

It’s also possible to export all your exchange data to PST for back-up or legal reasons :

Conclusion

I’m very enthousiastic about MigrationWiz and I think I will testdrive their other products also. Migration maildata is easy and works as it supposed to. Some minor improvements would be nice like the option to select the mailboxes instead of importing them with one of the bulk options. I also noticed that the impact on the source exchange system is noticeable, but you can tweak the options. So look out for importing all your exchange data during daytime without looking into the tweak options.

Messages stuck in Exchange 2010 queue (resolved)

0

Today a collegae of mine ran into a problem with Exchange 2010. Messages both internally/externally were not delivered. We noticed that the Exchange server was using 100% CPU resources.  After some investigation we noticed that the submission queue was building up.

We decided to suspend the queue, exporting the messages. Then deleting the queue and recreating it. Finally we imported the exported messages. We used the following steps :

First open the Exchange Management Shell

Show all Exchange queues

get-queue

Suspend all messages in this queue

get-queue exchangeserver#submission | get-message | suspend-message

Export all suspended messages

$array = @(Get-Message -Queue "ExchangeServer\submission" -ResultSize unlimited) 
$array | ForEach-Object {$i++;Export-Message $_.Identity | AssembleMessage -Path ("c:\Mailqueue\"+ $i +".eml")}

Stop the MsexchangeTransport service

Stop-Service MsExchangeTransport

Now rename the queue directory, the default directory is

Startthe MsexchangeTransport service

Start-Service MsExchangeTransport

Solved : All Exchange 2010 services disabled after update

0

Today I ran into a problem after updating Exchange 2010. After a reboot (which took ages!) I noticed that all the services were disabled. After some troubleshooting I found out that the problem had something to do with an installed update. My resolution (and was planned) was to install the latest servicepack (SP3). There is one drawback, the services are disabled and Exchange SP3 setup is unable to stop/start them.

I used this powershell command to set the service to manual :

Get-Service MSEx* | Set-Service -Startuptype manual

During the install I had to execute this command 2 times, the SP3 setup worked fine and after that the services were automatically started.

Exchange 2010/2013 : Unable to find schema master

0

Some time ago I ran into an error while installing Exchange. It seems this problem also occurs when upgrading/installing an Exchange Server service pack. This is how to fix this problem :

First go to the (root) domain controller and register the schema extension :

regsvr32 schmmgmt.dll

Now load the plugin by starting mmc and adding the extension

Now right-click the Active Directory Schema en select Change Active Directory Domain Controller. (Choose the domain controller you wish to transfer the schema role to)

schema001

Hit ok when you receive the read-only warning.

Now select Change Schema Master and hit Change.

Exchange 2003/2010 cross forest routing problem solved

0

For a customer I ran into a strange problem. While doing a cross forest mailbox migration I noticed that mails were queuing up and were not delivered. It took some troubleshooting untill I found the solution. First I noticed that newly created users received email for several domains without any problems. Migrated users didn’t receive any external email.

I opened the user’s properties with ADSIEDIT and I noticed the old email addresses on the targetaddress field. I decided to delete the values and re-register those email addresses using the Exchange console. The user concerned received external email immediately .

adsi001

Because it’s a cross forest migration we are using ADMT for the user migration. It’s possible to exclude this value and doing so will prohibit to these old values being migrated to the new domain.

Exchange 2010 move database error WMI exception occurred..

0

Today I tried to move a database to a different drive and I ran into the following problem :

PF_error

After some investigation I noticed a large amount of log files. After enabling circular logging and dismount and mounting the database everything went fine! Disable circular logging afterwards and make sure your backup solution is running working and flushes the logfiles correctly.
