Remove Team Calendar from Outlook

Outlook 2010 introduced a new feature:  Team Callendar.  Team Calendar is created automatically  based  on fields ‘Manager’ , ‘Direct Reports’ from AD.



Automatic configuration of this feature is very convenient. The problem appears when you do not want to see these calendars in Outlook. So we’ll have a little work.


Disable Team Calendar for single user

For single user simply disable this feature directly in Outlook. Expand ‘Calendar Groups‘ and deselect ‘Show Team Calendar‘, ‘Show Manager’s Team Calendar‘.





If we want to avoid user’s ability to manage these functions and permamently disable feature we can use Registry Editor.

So fire up regedit and create folowing  DWORD key:

This problem is not common but quite annoying and usually hard to understood by users.

In most cases problem occurs If you remove mailbox and re-create it with the same AD account , for an example after firing and  re-hiring of the employee after some time.

It also occurs after migrations.

When user sends an email to a recipient, to which earlier messages was delivered without any problem. Sudennly gets an Non Delivery Report with this content:

Delivery has failed to these recipients or distribution lists:: 

Test User

The recipient's e-mail address was not found in the recipient's e-mail system. Microsoft Exchange will not try to redeliver this message for you. Please check the e-mail address and try resending this message, or provide the following diagnostic text to your system administrator..

Diagnostic information for administrators: 

Generating server:

#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

And now the question is: Why?

Exchange recipients limit

In fact, this information is easily available on technet, but sometimes it is useful to organize and put them in one place.

Exchange 2010 and Exchange 2007  recipients limit

There is an important change compared to Exchange 2003 – Distribution group are treated as one recipient.

We can restrict recipients limit at the following levels:

  • Organization
  • Transport server
  • Receive Connector
  • Mailbox


Recipient limit  at the organization level, we can check this PowerShell command:

Get-TransportConfig | fl MaxRecipientEnvelopeLimit

or in EMC

Resume-MailboxDatabaseCopy for all databases on server

Sometimes (for example, after a small disk array failure ;)) you need to resume failed and suspended database copy. We can do that with this  command: resume-mailboxdatabasecopy .

But what if there is a lot of databases ?

In this case we can use this command to resume replication for all databases on specific server:

get-mailboxdatabasecopystatus -server “server_name” | resume-mailboxdatabasecopy

Also for suspending replication we can use this command:

get-mailboxdatabasecopystatus -server “server_name” | suspend-mailboxdatabasecopy

Exchange 2010 unable to sent Out of Office, Mail Tips problem

The problem of the peculiar cycle of failure.
Exchange 2010 no longer generate an automatic response (AutoReplay Outlook Out of Office). In Outlook 2010 does not also appear in the mail tips for absence.
There was no problem with setting OOF via Outlook and OWA.
Proved to be helpful to restart the Exchange Mailbox Assistants Services on the server.
The problem is basically trivial, but maybe someone will save time. The more that in Google for similar problems przypadu meets reconfiguration proposals and EWSa Autodiscover.
So before we start all over again to configure all the paths WebServices supported by the Exchange, we first try to restart the Exchange Mailbox Assistants service, perhaps so that we save a lot of time.

The solution can also be an additional dismount the database and mount it again.

In the case of DAG environment, just for a moment change the active database to another located on another server.
