Why does my "tab" key no longer cycle out of the "TO" area? Outlook Live Web Browser

I am having the same issue.

I have this same issue, noticed just a few days ago.

I have a Python script using PyAutoGui to replace the Macro functionality in the "Modern" Outlook experience. It's usually a bit hit and miss because Alt doesn't always bring up the Menu but usually it works. That was until last week when it would not longer compose the emails correctly. I narrowed it down to this Tab issue. The workaround is to enter the Subject and Body first, then Shift-Tab to the CC field and enter CC addresses, then Shift-Tab to the To field and enter the To addresses. After that Add any attachments.

I tested it with my Script and it works. However, Microsoft should clearly fix this bug!

I'm also having the same problem. Have they given a solution yet?

I am also having this issue. Shift+Tab works. Tab alone does not.

Good morning,

Within the past 2 days, my Outlook Live web browser will no longer tab from the "TO" field to the "CC" field or the "BCC" field when email addresses autopopulate into the "TO" field.

It has tabbed fine for almost 5 years for all contacts, but for the past few days, it will no longer work on any of the names in my contact list.

If I enter their name and then try to tab down to the subject line, it highlights the name in yellow, but it will never tab down to the other fields.

If I put my cursor in the subject line and then tab, the cursor will move from the subject line to the body of the email.

Why is the Outlook Live web browser functioning this way on certain names in my contact list?

I have cleared my cache and cookies.

I have tried using incognito mode.

Nothing has worked.
