I am using outlook on the web. Browser is Firefox ESR. I have no spaces between words in both incoming and outgoing e-mails and even subject lines.
Sending, receiving, and organizing email in Outlook.com
Sorry to hear that you are having trouble with this situation. Could you please test Outlook on the web using Microsoft Edge to check whether the issue is browser-related or related to a setting in your account?
Also, please let me know if this started suddenly or after making any changes to your email account or browser settings.
Did not make any changes to Browser. But problem cleared up when I closed browser completely (not just closed Outlook) and reopened the browser.
I do not have Edge, there is no version of Edge for this version of Windows.
Thank you for the update. Since the issue cleared after completely closing and reopening Firefox, this was most likely a temporary browser session, cache, or rendering issue rather than an Outlook account issue.
If it happens again, please try fully closing all Firefox windows and reopening the browser. If the problem returns, clear the Firefox cache/site data for Outlook.com, then test Outlook on the web again. Also, if you use any ad blocker, pop-up blocker, or other browser extensions, please temporarily disable them to check whether one of them is affecting Outlook’s page rendering.
