Issue with fonts on Outlook for Mac version 16.110 (26061317)

Question

Issue with fonts on Outlook for Mac version 16.110 (26061317)

James Burney 150

Device affected: MacBook Air, Apple M3

Following the update to the latest version of Outlook for Mac (16.110) some of our users are experiencing inconsistencies with fonts when drafting a new email, or replying to an email.

The user can type in the default font specified under Outlook > Settings > Composing > default fonts, until they change to any other font whilst composing the message.

When the selected font is changed, Outlook will display the new font name which the user selected, but it will be using Arial font.

After a different font has been selected, the typed font will always remain in Arial, even if another font is selected.

Reinstalling fonts manually to the Font Book, and resetting fonts via Font Book advanced settings did not make a difference to the behavior.

So far the only way I've been able to resolve the issue is by rolling back to a previous version of Outlook for Mac (109.2).

This update has been highly problematic, I hope MS can fix these issues ASAP.

This problem persists in Version 16.110.1 (26062112). I believe that it relates to the way that Outlook is now building the HTML that underpins the message.

I can see within the HTML of a (broken) message sent from this version on the Mac, that we have the following...

<div style="direction: ltr; font-family: Aptos, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">This should be courier</div>

Notice how the inline  has a font-family defined, but that the attempt to put quotes around the selected font name has produced an absolute mess.

The equivalent in an email sent from a Windows machine looks like...

This should be courier<o:p></o:p>

Interestingly, if I view the source on the Windows machine, I see...

This should be courier<o:p></o:p>

So there is a double problem with Outlook on Mac converting single quotes to doubles in received messages, and then mashing inline double quotes into ", in addition to whatever the heck it's doing when composing messages. If someone wants to pass that on to anyone that can actually fix this mess, then please do so.

@Hin-V are you wanting one new thread per person? Is that likely to attract the quickest response?

@Hin-V If everyone experiencing this issue did that, this would be a forum about this single bug only. You'd then be asking us to all contain it into one super thread.

So to reiterate my comment that was pruned, the issue is still present on 16.110.2, on both macOS 15 and 26, across all my users. This comment is for the sake of anyone landing here via internet search.

Hi @Andy LAW and @Ben Ford
I suggested opening separate threads not to fragment reports of the same symptom, but to ensure that each case is investigated as accurately as possible. Reports in a discussion may involve different Outlook versions and different environments. While the visible behavior may appear similar, the underlying cause can be different. Having a dedicated thread for each affected version or environment helps our team collect the appropriate diagnostic information and provide targeted updates without mixing data from multiple scenarios.

That said, all users are welcome to participate in the discussion, share their experiences, and describe the issues they are seeing. I will do my best to gather and consolidate feedback from everyone. However, if the information starts to diverge, for example, involving different versions, environments, symptoms, or troubleshooting results, I may separate the discussion into individual threads to avoid confusion and ensure each case receives focused investigation.

I understand this may seem somewhat complex, but it helps our team address each user's situation more effectively and avoid situations where guidance that applies to one environment is mistakenly assumed to apply to another.

If users on newer versions are encountering the same issue, please use Outlook > Help > Report a Problem to send feedback directly to the product team along with diagnostic information to assist the investigation.

Additionally, as Filip mentioned, the issue appears to be fixed in Outlook Version 16.112 (26063025) on the Beta Channel, which is an encouraging signal that an upcoming version release may contain the fix as well.

Appreciate your patience and understanding.

Font selection is now working as reported. I found I had to reapply the required font selection to my signature.

Format Painter tool is still not working, which I had raised as an issue with Support.

I have checked it myself and found the issue no longer present in Version 16.111 (26071325) per the above comment. Therefore if anyone is still experiencing this issue, the best resolution is to simply update to the latest version released July 14.

We're experiencing the same problem since Version 16.110 (26061317) was auto installed. Reported it via the Feedback including video of the issue and diagnostics. No fix yet. Anyone have an update on this problem?

Hi @Greg C

I truly understand how this issue is impacting your current workflow. At this time, Microsoft has not released any updates or a new version to address the issue. I will continue monitoring the situation and keep you informed as soon as new information becomes available.

Thank you for your patience and understanding.

Hello @Hin-V

This issue continues on 16.110.2 (26062818)

We have observed it across MacOS 15 and 26 builds, fairly universally with the people we work with. It is unclear what fixes where included in the last 3 builds based on the release notes, but I can confidently say resolution to this issue was not among them.

Recent chat with a support agent has them claiming this is fixed in "the upcoming Outlook update (currently in Beta)" build and we can expect a fix in some amount of weeks they could not specify.

Fingers crossed

Problem persists for me too with 26070318. I've created a separate thread at https://learn.microsoft.com/en-us/answers/questions/5940961/issue-with-fonts-on-outlook-for-mac-persists-in-16 to satisfy previous requests from @Hin-V and to emphasise that this is not yet fixed

Has it fixed the Format Painter as well.

Using the Format painter fails to apply the copied format to the selected text.

Have already reported this and got this reply:

We have reported this as a bug to our product team for further investigation. As there is no ETA on this, please keep Outlook updated to get the fix once it is available. As there is no action required from support, we shall close this ticket for now.
