how to add the a category before sending an e-mail

Hi @Ferdinand Strohmeier, 

I hope you’re doing well. Thank you for posting your question in the Microsoft Q&A forum. 

From my research, Outlook for Android doesn’t support adding/applying a Category from the email compose screen before sending. Categories in Outlook for Android are primarily applied to emails that already exist in your mailbox (such as Inbox or Sent Items) via message actions in the reading pane / message list (including options like long-press multi-select and swipe actions).  

In the meantime, as a workaround you can send the email as usual then go to Sent > open the message > use the More (⋯) menu / message actions > Categorize 

This aligns with how Categories are currently applied on Android (through actions on existing messages).  

Additionally, if you’re forwarding an existing email. You can categorize the original email first (in Inbox), then forward it.

I agree with you that being able to assign a Category during composition would be very useful especially for workflows that rely on consistent labeling, triage, and tracking across devices. I can see how this could meaningfully improve efficiency and the overall mobile experience. 

As a forum moderator, I hope you understand that I don’t have the ability to modify or escalate product issues directly. However, I strongly recommend submitting your feedback through: 

• In the Outlook mobile app: Settings > Help & Feedback > Send Feedback  
• Or the Outlook · Community portal 

This is the most effective way to ensure your voice reaches the product team and can be considered for future improvements.
