Email & Outlook Problems
Outlook not opening, not sending, or asking for your password on repeat — common causes and what's worth checking first.
Outlook problems tend to fall into a handful of categories — the program itself won't open or crashes, email isn't sending or arriving properly, or an account keeps asking to be signed back in. Each has a different likely cause, and it's rarely worth trying random fixes before narrowing down which category you're actually dealing with. The guides below cover the most common Outlook and email problems, including when a corrupted profile is the underlying cause of several seemingly unrelated symptoms.
