Exchange and Antiviruses

2013-05-30T09:57:00Z

Many times it has been seen in support that Antiviruses cause all kind of issues. I thought we should also discuss one of them I recently came upon and see how we could resolve it. Let's take Exchange 2003 for Example and the Sophos Antivirus. This can be the case also with Exchange 2010 or 2013. We have a User for example that doesn't receive Emails from a specific Sender, only when other people are in the TO: field also. If the Email is being sent only to our affected User, this works...(read more)

How do Retention Policies work under specific scenarios?

2013-05-20T08:43:00Z

Let’s take the following example: We have an Exchange 2010 User who is traveling a lot (Sales person for example). On his Mailbox we have a Retention Policy for 60 days on his Inbox and 2 years on his other Folders. User takes his Outlook offline (traveling). Some of his Emails expire tomorrow for example. He takes the Emails that expired with 60 days in his Inbox and moves them to a Folder that has a Retention Period of 2 years. After coming back to work, he takes his Outlook...(read more)

Full Mailbox Access Rights + Send On Behalf = Send As ?

2012-04-06T14:40:00Z

The following is valid for Exchange 2007 and Exchange 2010. Consider the following Scenario: We have two Users: User A ( UserA@mp3.lol ) and User B ( UserB@mp3.lol ). You grant User B Full Access Permission for User A’s Mailbox: Additionally you grant User B also Send on Behalf Rights for User A’s Mailbox: Now User B should be able to Send On Behalf of User A, right? Right! Or at least 50% right… User B configures an Outlook Profile for User A, using...(read more)

The "not so simple" Simple Display Name

2012-03-26T07:50:00Z

Consider the following scenario: This applies both to Exchange 2007 and Exchange 2010. We have two Users : User1 ( User1@mp3.lol ): Display Name : User 1 Simple DisplayName : User One User2 ( User2@mp3.lol ): Display Name : User 2 Simple Display Name : N/A ( not configured ) We have one Remote-Domain: Default.

We receive NDR 550 5.6.0." smtpsendrdstnottransmittable" when sending e-mail to mail-enabled Public Folder on Exchange 2003

2012-01-18T13:16:00Z

You just installed Exchange 2007 or 2010 in coexistence with Exchange 2003 in order to proceed to migration. When performing tests you realise that you are unable to send any e-mail to the Public folders that are not yet replicated on the new server(s), or worse, you try to replicate the public folders to the new server and you observe that the queue gets full and nothing gets to the post 2003 servers. For both case you receive an NDR 550 5.6.0." smtpsendrdstnottransmittable" in message tracking...(read more)

NDR storm between members of a distribution list in Exchange 2010/2007.

2011-04-28T09:46:00Z

I recently came across a very interesting issue that is affecting Exchange 2007 all versions but also Exchange 2010 all versions as well. We have the following scenario: a distribution list that has external contacts, we have set the option on the distribution list “Send delivery reports to message originator”, external contact has an issue with his email address and let’s assume an NDR is generated. An external user Dan sends an email to this distribution list and the NDR generated...(read more)

Another Method of Obtaining ExTRA Traces http://blogs.technet.com/b/scotch/archive/2010/04/05/another-method-of-obtaining-extra-traces.aspx We know that the ExTRA tool sometimes fails to log anything in the .etl file.

Some PowerShell commands will not show all the information

2010-12-06T08:55:46Z
