[Update]: This blog post was last updated on August 5, 2024 to reflect the latest changes in how app passwords are handled in Microsoft 365.
Some non-browser applications and services for Microsoft 365 use app passwords as an authentication method when multi-factor authentication (MFA) is enabled. The problem is that after enabling MFA for the organization, some or even all users may not be able to create and use app passwords. This article shows what you can do if you find out that app passwords are not working in your Microsoft 365 tenant. Continue reading...

[Update]: This blog post was last updated on June 28, 2024 to reflect the latest changes in Microsoft 365 Copilot licensing requirements.
AI, or Artificial Intelligence in full, is a hot topic these days – no matter if we speak about personal or professional context. The popular Microsoft 365 offering from Microsoft has been AI-enabled at the end of 2023 through the introduction of Copilot, a solution to boost end-users’ productivity.

[Update]: This blog post was last updated on April 22, 2024. Search-Mailbox seems to be gone for good and the new method’s limit is upgraded from 10 to 100 items.
As announced in this Microsoft article, the date for retirement of legacy eDiscovery tools was moved from April 1, 2020 to July 1, 2020. That is when Search-Mailbox cmdlet lost its official support. While the Search-Mailbox did work for some time after this date, now you can use it only on on-premises Exchange. What about Exchange Online and Microsoft 365? Well, there’s a new sheriff in town and its name is New-ComplianceSearch. The cmdlet is a bit more troublesome to use, so I’ll do my best to show you how to come to terms with it. Continue reading...
[Update]:The article was updated on April 15, 2024 to reflect UI changes and the latest developments in Microsoft Viva apps.
Microsoft has been promoting Viva for nearly 4 years now as ‘an employee experience platform that brings together communications, knowledge, learning, resources, and insights in the flow of work.’ Maybe it’s just me, but this description doesn’t really explain what Microsoft Viva is, and what to expect from it. That’s why I’ve dived into this subject to give you a straightforward description of Viva, admin to admin. Continue reading...
[Update]: The article was updated on March 26, 2024 to reflect the latest developments in Microsoft 365 message encryption, e.g. licensing requirements.
Email encryption provides additional layer of information security by making sure only intended recipients can read messages. If you are looking for a user-friendly email encryption solution for your Microsoft 365 organization, there is a native tool for that – Office 365 Message Encryption (OME). Now, although the OME name is still in use, the official, up-to-date name is Microsoft Purview Message Encryption. It’s not quite the same, since OME was deprecated on July 1, 2023. But, like with most name changes, OME is and probably will be used for a long, long time to come, so I’ll use it interchangeably. Anyway, from the user’s perspective, OME is the easiest encryption method to use: it can be configured so that it does not require any additional actions on their part. From the recipient’s perspective, this form of email encryption works seamlessly with Microsoft 365 accounts and offers an intuitive experience for all other email clients and email service providers. Read on to learn how to create a Microsoft 365 sensitivity label and use it in a transport rule to encrypt emails and files.

Read on to learn why you should not ignore it and how to deal with it as a Microsoft 365 administrator. Continue reading...
[Update]: There was a change in the rollout timeline. We’ve also shown how to pause email throttling and blocking if your Microsoft 365 tenant is affected.
Microsoft throttles and even blocks emails sent from Exchange Server to Exchange Online. The transport-based enforcement system reports emails sent from vulnerable Exchange Servers and gradually delays and blocks mail flow to force admins to update their on-prem environments. This is to ensure superior security of Microsoft 365 organizations. See if the feature affects you and what you can do to keep your mail flow running. Continue reading...
