I see the exact same issue, specially when trying to edit the font style when composing an email. I see the spinning circle with the text format field blank.
This appears to be an issue with the Outlook app itself on iOS.
Outlook iOS chosen default font stopped working and font within email can’t be chosen either

In Outlook for iOS, the chosen “default” font no longer applies to new emails or in reply to other emails.
But within an email:
Similarly, within an email message it is not possible to specify any font; when opening the font choosing window the following appears:
I have deleted and reinstalled the Outlook app. I am experiencing this across three iOS devices.

I have the exact same issue as well described above, which makes me unable to use Outlook mobile for now as our company writes in Calibri 11 and will not change now.
As I am IT admin in my company, I can affirm that we have not changed a single policy. Besides, this is a problem that appeared exactly since the latest app update on iOS. As such, it should be flagged to tech team ASAP so that the next update fixes this.
Thank you very much in advance.
Best,
Andy

2025-12-04T20:07:43.67+00:00 Hi @Ryan-N ,
Thank you for your suggestion. However, I find it difficult to understand why the process always requires going through support, as this often results in significant delays with repeated log exchanges, level transfers, and escalations. From my perspective, it would be far more efficient if Microsoft provided a dedicated portal to report bugs directly, taking responsibility for verifying and resolving them without placing the burden on customers to navigate such a time‑consuming process.

2025-12-04T21:15:53.86+00:00 Hi @Federico Piazza,
Thank you for sharing your concern.
When you create a ticket through the Admin Center, the support team will perform an in-depth check of the system settings to ensure that your tenant’s configurations are completely normal (this process will not compromise your personal information). However, any changes to these settings may affect all users within the tenant.
Therefore, creating a ticket via the Admin Center is the safest way to maintain the system’s proper operation. For this reason, ticket creation can only be performed by the tenant administrator and requires a thorough information-gathering process as described above.
If you have any other questions, please feel free to share them with me. I’m always ready to assist you.

Microsoft has just released a new Outlook version for iOS, 5.2548.0.
It seems that the font issue is now resolved with this update.

2025-12-03T16:45:21.8533333+00:00 Hi @DEDoubleU,
Welcome to the Microsoft Q&A forum.
Thank you for sharing detailed information about the issue with changing fonts in the Outlook app for iOS. I understand this feature is important and appreciate the effort you put into providing such thorough details.
Based on my test environment, changing fonts in Outlook for iOS is still functioning normally:
The issue may stem from the following cause:
- A configuration within your organization’s internal system or a tenant policy may have inadvertently been applied, preventing font changes in Outlook for iOS.
In this case, I recommend contacting Microsoft Support for a deeper investigation into the system and verifying whether any policy has been unintentionally applied to accounts within the tenant (this will not compromise your personal or organizational data).
Once you create a support ticket, a live agent from Microsoft will reach out to you directly and assist with remote troubleshooting to resolve the issue.
To create a ticket, please follow these steps (requires an account with admin rights in the tenant):
- Go to: https://admin.microsoft.com
- Click Help and Support
- Enter the subject: Unable to change font in Outlook for iOS
- Click Contact Us
- Choose your preferred contact method
After the system receives your ticket and assigns it to Microsoft’s Outlook technical support team, a live agent will proactively contact you using the method you selected and guide you step by step until the issue is fully resolved.
Note: We appreciate your understanding regarding the scope of support provided through this forum. As moderators, our role is to offer general guidance and assist with common troubleshooting steps. We do not have access to internal systems or administrative tools required to resolve account or backend issues, but we will continue to support you within our responsibilities.
I hope this information is helpful. Please follow the steps above and let me know if they resolve the issue. If not, I am ready to continue working with you to find a solution.
Thank you for your patience and understanding throughout this process. If you have any further questions or need additional assistance, please do not hesitate to reach out.
I look forward to your response.
