Technical HUB

As we work for our customers, we often find ourselves in a position where we know it's not only our problem but most likely, a lot of people will hit this sooner or later. This Technical Hub provides our customers and us with solutions, scripts, and other information useful for Administrators and, to some degree, for non-technical people.

420-recipient_deferred_because_there_is_no_mdb
14 Nov: Microsoft Exchange – 420 4.2.0 Recipient deferred because there is no Mdb

Last few weeks I'm responsible for migrating from Office 365 to Office 365. Part of this migration process is to set up new Exchange 2016 server that will work as relay instead of using IIS server. I've setup hybrid, added accepted domains, prepared connectors, but there's one thing missing. Any time an email is sent via relay to a user that exists on Office 365 and at the same time exists in Active Directory email never gets there.

Bittitan
13 Nov: Bittitan MigrationWiz – Users getting undergoing maintenance message

MigrationWiz from Bittitan is one of the best tools on the market allowing for migration of user mailboxes. Whether it's a google account, exchange account or IMAP, it will help you out. Last few months I'm part of migration project that is using Bittitan at its core. One of the signature features of this tool is the ability to migrate mailboxes from Office 365 tenant to Office 365 tenant. This is not something that every application can do. Another feature (and something I want to address today) is the ability to ask users for their logins and password to migrate their data from one tenant to another tenant. While in general, you shouldn't do that and you should use migration accounts with proper permissions sometimes you have no other choice.

Synchronization Rules
09 Nov: Azure AD Connect – Synchronizing MAIL field with UserPrincipalName in Azure

Azure AD Connect is an application responsible for synchronizing Active Directory with Azure AD allowing for a natural population of users, groups, and devices in Office 365. While for most companies standard setup is very easy and most of the time touch-free, there are companies which require greater customization. During installation of AD Connector, you choose what should be used for Azure AD Username from your AD. UserPrincipalName field is an obvious choice for this and also proposed by default for that purpose. This field is utilized further by your users to log in to your Exchange, SharePoint, Teams and so on.

PSBlackListChecker Discord
03 Nov: PSBlackListChecker – Added Discord support

It's been less than 24 hours since I've released PSBlackListChecker with support, among other improvements, for Microsoft Teams and Slack and I'm now adding Discord to the mix. Discord was a popular request (well not really, just one person asked, but let's pretend everyone loves PSBlackListChecker so much that they are too shy to ask for feature requests!).
