Exchange After-Migration Update

Exchange After-Migration Update

We wanted to offer a major update on the migration, specifically covering the major issues we have addressed for some clients during the cleanup phase.

Distribution groups, forwarding

We have received reports from several organizations regarding issues covering distribution groups, group members, forwarding account directions (forward vs. store & forward). If any objects failed to import due to configuration/contents/policy/etc it is in the retry queue and will be published shortly.

Add / Delete Mailbox

We have addressed a bug in the add/remove process that was prohibiting certain organizations to add/remove accounts. Originally, as noted on anythingdown.com NOC, we blocked this function entirely because users were looking at an empty list and creating mailboxes (that would cause a collision when the new mailbox was migrated from the source). This problem is fixed, if you encounter an issue please open a ticket with a screenshot and as much info as you can provide.

Add / Delete Organization/Domain

At this moment it is not possible to add/remove organizations, or those that were in the system recently. In order to finalize the migration, the routing policies are locked down (meaning if you deleted a domain, ExchangeDefender will still treat them as local). We look forward to wrapping this up shortly.

Password / Login issues

This is by far the biggest ticket group category, we are still processing double digit requests for credentials, credential resets, and credential tests. Similar to the next group:

Outlook issues

We are still spending a lot of time going through the basic Outlook configuration steps. For an overwhelming majority, this transition has been transparent. Those that did not and had to take a manual configuration route, the process has been described at anythingdown.com 1) Make sure you have an autodiscover record 2) Make sure it propagates, then run the autodiscoverregistryhacks.zip 3) If you don’t control your DNS, make adjustments to your local systems hosts file 4) Setup Outlook with autodiscover, the UPN must be used as your login address if you’ve changed it from your primary SMTP address.

Missing & Syncing Emails

Every mailbox that has been reconnected has either had all it’s mail delivered directly, delivered in a Catchall account – user@domain.com. Some users are confusing items they see in their Inbox in LiveArchive but not in their Outlook/OWA (but after extensive searching we keep on finding missing messages in folders, Deleted Items, etc). If something is missing and absolutely critical in LiveArchive just click on the message and click Forward to your email address and the message will be forwarded to your Outlook/OWA.

Store & Forward

Several users were also unfortunately caught up in a custom policy that did not get migrated to the new Exchange. These are more legacy configs we did for some users in AUDC, things like renaming the OU or primary domains. For some of those accounts, the store and forward rule because a forwarding only rule, skipping the Inbox and going straight to the person that it’s being copied to. We have fixed this issue and it should not be happening again.

Autodiscover

We have gotten several complaints about autodiscover. Microsoft has removed manual configurations in 2013 and no modern version of Microsoft Exchange supports a manual server setup. However, this is something that could be easily rectified even with minimal technical skills by modifying the local hosts file if you don’t have the credentials to do it properly by modifying the DNS. Absolutely everything in the new infrastructure relies on the autodiscover record!

iPhone / Android Setup

For the most part, we are just confirming that all mobile devices should work fine with owa.xd.email as the server name, ditto for EWS integrated applications, we have not received more than an inquiry for the server name. For Android, things get sketchier when you consider all the different vendors, apps, and configurations. Again, so long as autodiscover is present and configured properly and your device is using a modern client, it should just work. When it doesn’t, recreating it takes a few minutes.

NDR

Non delivery receipts and errors are always of high interest to our NOC team as we continue to go through cleanup and audit all the tickets and users.

These are the issues we are currently working on, in 3 shifts, and sorting them all out as fast as possible. I know that for many of our clients this transition has been messy, but you are on such a better and more secure platform that won’t require you go through this process again. While modern platforms are more secure, their recovery from a disaster or issue (as some of you unfortunately went through) is extensive and at times unpredictably slow – so you have this much of a commitment for us, we will make sure LiveArchive is able to step in on a whole new level when things like this happen.
