Follow me We recently did a migration from Exchange 2010 to Exchange 2013, after moving the mailboxes to Exchange 2013 we realised that we are Unable to apply Retention Policy on Exchange 2013 for migrated mailboxes. Further investigation revealed that if MRM1.0 (Messaging Records Management) policy was applied on mailboxes while on Exchange 2010 or Exchange 2007 than the old policy will prevent MRM2.0 policy from getting applied once the mailboxes are migrated to Exchange 2013. Read more about MRM here Solution We have a couple of solutions to fix this issue 1) Move the problem mailbox back to Exchange 2010 or 2007 and remove the MRM 1.0 policy from the mailboxes using the following cmdlet Set-Mailbox -Identity -RemoveManagedFolderAndPolicy Once the MRM policy is removed than move the mailbox back to Exchange 2013 and than apply the new MRM 2.0 2) The second solution we have is a little more technical but also very practical. When an MRM policy is applied on a user than user attribute “MsExchMailboxTemplateLink’ is updated with the distinguishedName of the Managed folder mailbox policy. And this attribute remains populated even when the mailbox/user is migrated to Exchange 2013. So the solution is to access the problem user via adsiedit.msc and clear this attribute there. Once it is cleared than we should be able to apply the MRM 2.0 policy without any concern. If we do not want to move the user back to Exchange 2007 then in that case we can follow the below step. If the user is applied to any MRM 1.0 policy in Exchange 2007 then the attribute ‘MsExchMailboxTemplateLink’ is populated with...

Follow me If a user setup an outlook rule to auto forward all the emails to some other user, than the end user cannot find out the original sender of the email. Solution Unfortunately none, this is by design and has been an issue since Exchange 2003 and is present uptil Exchange 2013, though there are a couple of workarounds to the issue 1) While creating the auto forward rule, select the option to Blind Carbon copy (BCC)the message to addresses” and provide the required recipient addresses 2) Or you can always modify the rule to forward the email as an attachment to required people or group Feel free to start a new thread on our forum to seek expert help.

NDR with junk email address It is not uncommon that in Microsoft Exchange environment some times a user to whom uptill yesterday everyone was able to send the email, suddenly all the internal users start to get an NDR (Non Delivery Report) with a junk email address when trying to send email to the person. And If you are unlucky as me then that guy would always be some VVIP of the company 🙂 . we receive complain like some users are not able to send email to a particular user, and they get NDR as below: You might notice the user name is hyper linked and when you resolve it by pressing (Ctrl+Click) , new memo opens with junk email id. Example: Delivery has failed to these recipients or groups: Harish Chadda The email address you entered couldn’t be found. Please check the recipient’s email address and try to resend the message. If the problem continues, please contact your helpdesk.

This issue occurs because the value for the LegacyExchangeDN attribute changed. The auto-complete cache in Microsoft Outlook and in Microsoft Outlook Web App (OWA) uses the value of the LegacyExchangeDN attribute to route email messages internally. If the value changes, the delivery of email messages may fail with...
