Office 365 Mailbox Migration – Target Mailbox Doesn‎’t Have An SMTP Proxy Matching

Posted on 20th August 2015 by Rhoderick Milne [MSFT]

When migrating mailboxes from on-premises Exchange to Office 365, we can run into the error where the migration fails with an error stating that the target mailbox doesn’t have an SMTP proxy matching the Microsoft Online Routing Domain.

This can happen due to a number of causes. For example the mailbox is managed by an Email Address Policy (EAP) that was not updated with the online routing domain.… Read the rest “Office 365 Mailbox Migration – Target Mailbox Doesn‎’t Have An SMTP Proxy Matching”

Add-DatabaseAvailabilityGroupServer – You Must Provide A Value For This Property

Posted on 29th July 2015 by Rhoderick Milne [MSFT]

When creating a new Database Availability Group, there was a bit of rude shock when the installation failed. This customer had deployed multiple Exchange 2010 DAGs over the lifespan of the product, yet their latest build ran into an issue. They were able to create the DAG, but when adding the first mailbox server to the DAG, the operation failed.

This was not due to an underlying issue where the W… Read the rest “Add-DatabaseAvailabilityGroupServer – You Must Provide A Value For This Property”

Exchange 2013 CU9 MessageCopyForSentAsEnabled Missing

Posted on 22nd June 2015 by Rhoderick Milne [MSFT]

After upgrading an Exchange 2013 CU8 lab to CU9, the Set-Mailbox cmdlet did not present the expected options to configure sent items for shared mailboxes.

The MessageCopyForSentAsEnabled and MessageCopyForSendOnBehalfEnabled parameters as discussed on the EHLO blog were missing.

This was a little puzzling as this was an expected feature of Exchange 2013 CU9. None of the issue… Read the rest “Exchange 2013 CU9 MessageCopyForSentAsEnabled Missing”

Outlook Prompts For Domain Certificate Unexpectedly

Posted on 10th June 2015 by Rhoderick Milne [MSFT]

Ran into an issue where this Outlook 2010 SP2 client, build 14.0.7113.5000, was throwing up unexpected certificate errors for the domain. This is the Tailspintoys.ca domain.

User-1@tailspintoys.ca was complaining about the below certificate error:

Looking at the error message, the fact that it is the domain (tailspintoys.ca), and not a FQDN is a hint. More on that later…

Unable to Reply to Old Emails Due to legacyExchangeDN

Posted on 3rd June 2015 by Rhoderick Milne [MSFT]

This is one of those ye olde issues that keep coming back up in Exchange. Have you every removed a mailbox, re-created it with the exact same SMTP address and then some people complain that they cannot send to the mailbox?

This can happen in a few circumstances. For example if the Exchange administrator has an “oops” and accidently deletes the account. If they do not use the AD DS recycle bin f… Read the rest “Unable to Reply to Old Emails Due to legacyExchangeDN”

Allow Users To Manage Distribution Groups Without Creating New Ones–Exchange 2013 Redux

Posted on 27th May 2015 by Rhoderick Milne [MSFT]

In a previous Exchange 2010 post we discussed a scenario where users were delegated the capability to create Mail Enabled Contacts in Active Directory using a custom Role Based Access Control (RBAC) role. As part of the solution, we enabled the MyDistributionGroups Role. While this may meet the needs of most organisations, it does introduce one issue where users who are assigned such a Role Assig… Read the rest “Allow Users To Manage Distribution Groups Without Creating New Ones–Exchange 2013 Redux”

Troubleshooting Exchange 2010 Search

Posted on 7th May 2015 by Rhoderick Milne [MSFT]

Since Exchange servers are now storing an ever increasing amount of data, it is imperative that people can quickly search and retrieve the content from their mailbox. This may have been possible without search capabilities in the past with a 20 MB mailbox quota (remember those days ?!?), but as quotas move to double gigabyte figures effective search is a hard requirement.

Exchange Search is a diffe… Read the rest “Troubleshooting Exchange 2010 Search”
