Microsoft MFA : Enabled or Enforced

Multi Factor Authentication (MFA)

Microsoft recommends using multi factor authentication for global tenant administrators. If you don’t do this, 60 days after the last reminder from Microsoft, the tenant is deactivated.

Warning: it’s not enough to activate 2-factor authentication … you also have to use it.

Enabled or Enforced

The problem is that activation is not enough. In fact, after activating the user, he must also log in with the MFA: at this point the user’s status changes from Enabled to Enforced.

You don’t have to have Global Admin with MFA in Enabled status but only in Enforced status.

Restrictions and limitations in OneDrive Web Download

onedrive

We had a problem downloading folders using Onedrive web. Under some conditions the download of a folder stops or the result does not contain all the files of the source folder.
When we contacted Microsoft, we learned that there is a limit on downloading folders using Onedrive web:

  • The folder cannot contain more than 50,000 files
  • The single file cannot exceed 15GB in size.

Microsoft recommends using Onedrive client.

outlook desktop client : unable to manage groups

For some days now, anyone who has an Exchange online mailbox and uses Outlook for e-mail has not been able to manage groups.
After doing all the recommended tests on the internet, we opened a support ticket to Microsoft who replied: “This is a global system crash which you could monitor from the admin interface”

We report the detail of the Microsoft report.

April 19, 2023 7:58 PM

Title: Some users may be unable to view or access group calendars and email messages in the Outlook desktop client User impact: Users may be unable to view or access Microsoft 365 group calendars and email messages in the Outlook desktop client.

More info: Affected users are part of a Microsoft 365 group and are on versions 16.0.16222.10000 or higher, including the latest February release channel. Some affected users may also notice that impact self-resolves after some time, although impact may also reoccur at a later time. These users may also be unable to perform one or more of the following actions in the Outlook desktop client:

  • Add or access the group mailbox
  • Add or access the group calendar
  • Add, remove, or edit group members
  • Changes to mail items, such as marking as read, archiving, or moving email to other folders.

Until a fix is deployed for this issue, impacted users with access to Outlook on the web can use that connection method to access the impacted group features.

Alternatively, impacted users can revert to Outlook desktop client build 16130.20332. The steps are outlined in the following article: https://support.microsoft.com/en-us/topic/how-to-revert-to-an-earlier-version-of-office-2bd5c457-a917-d57e-35a1-f709e3dda841

Current status: We’ve validated the fix and are preparing deployment to the impacted environments. We anticipate the deployment will start by our next communications update, at which we’ll be able to provide an estimated deployment timeline if available. While we’re preparing the deployment of the new build, we recommend impacted users revert to Outlook desktop client build 16130.20332, as mentioned above for immediate remediation.

Scope of impact: Impact is limited to users on versions 16.0.16222.10000 or higher, and are attempting to access or perform various Microsoft 365 group related actions in the Outlook desktop client.

Start time: Sunday, March 19, 2023, 1:00 AM (12:00 AM UTC)

Root cause: A recent service update is incorrectly triggering an indexer to delete specific values within the Outlook desktop client for some users, resulting in impact.

April 25, 2023 8:16 PM

Estimated time to resolve: We anticipate that the deployment of the fix will completely saturate the affected environments and fully remediate impact on Tuesday, May 2, 2023.

Next update by: Tuesday, May 2, 2023, 9:00 PM (7:00 PM UTC)

 

Aprile 26. Microsoft’s workaround

Revert to the Outlook Desktop build prior to the issue occurring, build 16130.20332.  You can use ODT steps, How to revert to an earlier version of Office or by following the steps below.

To revert to the prior build, do the following:

  1. Open a Command Prompt (Run as Administrator).
  2. Type/paste the following commands and press Enter after each: 
    cd %programfiles%\Common Files\Microsoft Shared\ClickToRun
    officec2rclient.exe /update user updatetoversion=16.0.16130.20332
  3. In the backstage, disable Updates (File, Office Account, Update Options, Disable Updates).
  4. Set a reminder on your calendar for May 9, 2023, to remember to re-enable updates. The fix should be out sooner, but May 9 is Patch Tuesday, and the fix will be in this update.

Outlook search doesn’t work (from December 2021)

In these first days of 2022 you may have problems in the search function of your Outlook. For example, you might want to search for emails from a certain contact and only get emails received before 2022.

The problem is caused by a Windows update affecting the Windows search function. The update is KB5008212. Then check for Windows updates to see if you have this update installed.

How to solve?

To date (12th January 2022) Microsoft has not yet released an update that fixes the problem.

If you’re in serious trouble and don’t want to wait, Microsoft has released a workaround that disables the “Windows Desktop Search” which is the source of the problem for Outlook. It is an operation to be performed on the registry. At this link you will find the official Microsoft statement and the instructions for the workaround: Outlook Search not showing recent emails after Windows update KB5008212

Outlook – font used in replying emails

When replying to an email with Outlook it may happen that you write the text using a different font than the one you normally use. For example it could be different in type and size (smaller!). The problem is that Outlook uses the font used by the sender in response.

To force the email to always use the same font you have to go to File – Options. In the configuration mask that appears, select the “Mail” block on the left, click on the “Decorative elements and fonts” button and set the desired fonts.
