outlook "trying to connect" status troubleshooting

TL;DR

Trying to connect in Outlook means the client cannot reach the mailbox server: network or autodiscover failure, a corrupt profile, or a stuck OST. Check connectivity first, then rebuild the profile before doing anything drastic.

The query

outlook "trying to connect" status troubleshooting

Use this when

• Outlook status stuck on trying to connect
• one user affected while others are fine
• after a password change Outlook never reconnects

Not for

• Outlook connected but mail not syncing (different symptom)
• OWA working fine is a clue, not the fix
• server-side Exchange outages (check service health)

Steps

1. Confirm the machine has internet and can reach the mail service; test OWA in the browser. Expected output: you know whether the network or Outlook is at fault
2. Restart Outlook and, if needed, the machine. Expected output: a clean client state
3. Check for a proxy or VPN interfering with autodiscover. Expected output: no middlebox blocking the connection
4. Create a new Outlook profile and add the account fresh. Expected output: a clean profile
5. If the new profile connects, remove the old one; if not, repair the Office install. Expected output: the faulty layer identified
6. As a last resort, rebuild the OST by deleting it and letting Outlook resync. Expected output: a fresh local cache
