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”

And now for some off topic humour…

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”

Posted on 14th May 2015 by Rhoderick Milne [MSFT]

When deploying an Office 365 solution, directory synchronisation is a critical component. This is the tool that will synchronise the on-premises directory data to Windows Azure Active Directory (WAAD). As you can imagine if the synchronisation stops then chances are that you will run into some issues….

Note that this post is intended to cover both DirSync and AAD Sync, hence the generic title.

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.
