Hi Scott,
Generally, when composing emails using the Outlook desktop client, we can enter the Tab key to make the cursor move forward. However, the feature is not feasible when using OWA(Outlook Web App). In OWA, we need to click the Increase indent button to achieve the goal.
As a result, may I know if you use OWA when you execute "Tab Space"? If so, it could be an expected behavior. However, if I misunderstood the scenario, please share the following information to troubleshoot the problem:
- Which type of Outlook client do you use, Outlook for Windows client, Outlook for Mac client or any other application?
- Let us know the detailed version of the affected Outlook.
- Screenshots about the symptom you encounter.
Looking forward to your updates.
Best Regards,
Ruel
