What to Do When Outlook Won't Sync After an Update
A few quick checks before you open a ticket — and what we'll do if it's still stuck.
Microsoft 365 updates occasionally leave Outlook unable to send or receive. Before calling us, try these three steps:
1. Restart Outlook completely. Close it, wait ten seconds, reopen. Most sync hiccups clear right here.
2. Check your connection status. Look at the bottom bar of Outlook. If it says "Working Offline," go to the Send/Receive tab and click "Work Offline" to toggle it back on.
3. Sign out and back in. Go to File → Office Account → Sign Out, then sign back in with your work email. This refreshes your saved credentials — the most common cause after an update.
Still not syncing? Open a ticket or call (201) 474-2703. A technician will start a remote session, clear the stuck credential cache, and re-authenticate your profile — typically a same-day fix. If several people in your office hit this at once, mention that when you call: we'll fix everyone in one session.
