Setting up Outlook on a new PC is one of those tasks that looks simple on the surface but has a handful of steps that regularly catch people out. Getting your email account connected is usually straightforward, but bringing across your old emails, recreating your signature, and getting all your add-ins and rules back in place takes a little more effort. This guide walks you through every step in the right order so you do not miss anything and end up with Outlook working exactly as it did on your old machine.
\n\n\n\nWhat You Need Before You Start
\n\n\n\nBefore you open Outlook for the first time on your new PC, it is worth gathering a few things so you are not hunting around mid-setup.
- \n
- Your Microsoft 365 licence or email credentials. If your organisation uses Microsoft 365 or an Exchange server, you will need your email address and password. For IMAP or POP accounts (such as a web hosting mailbox), you will also need the incoming and outgoing server addresses, ports, and whether SSL is required — your hosting provider or IT team can supply these. \n\n\n
- A PST backup or access to your old PC. If you want to bring across emails that are stored locally — anything that was in a local folder rather than on the server — you will need a PST file exported from your old machine. If the old PC is still available and on the same network, you may be able to copy the PST directly. \n\n\n
- A note of your installed add-ins. Add-ins such as CRM connectors, grammar tools, or email tracking plugins are tied to the local installation and will not transfer automatically. If possible, open Outlook on your old PC before decommissioning it, go to File, then Options, then Add-ins, and make a note of everything listed there along with any licence keys you will need to reactivate them. \n\n\n
- Your email signature text. Signatures are stored locally on each machine. Copying the text and any images from your old PC now will save you recreating it from scratch later. \n
Step 1 — Install Microsoft 365
\n\n\n\nIf Microsoft 365 is not already installed on your new PC, you will need to download and install it before you can open Outlook. Visit office.com and sign in with your Microsoft account or your work Microsoft 365 credentials. From your account dashboard, select Install apps and then Microsoft 365 apps. The installer will download and walk you through the process. The full suite including Outlook typically installs within ten to fifteen minutes depending on your connection speed.
\n\n\n\nIf your PC is managed by an IT department, Microsoft 365 may already be installed or may be available through a company software portal. Check with your IT team before downloading it yourself to avoid licence conflicts. Some organisations also use a standalone version of Outlook bundled with an older Office suite — if that is the case, your IT team will handle the installation.
\n\n\n\nStep 2 — Add Your Email Account
\n\n\n\nWhen you open Outlook for the first time, it will immediately prompt you to add an email account. Enter your email address and click Connect. For Microsoft 365 and Exchange accounts, Outlook uses a process called autodiscover to locate the correct server settings automatically. In most cases you simply enter your email address, click through the prompts, and Outlook handles the rest. If your organisation uses multi-factor authentication, you will be redirected to a sign-in window where you authenticate in the usual way.
\n\n\n\nFor IMAP or POP accounts — such as a mailbox hosted with a web provider — autodiscover may not work, and you will need to enter the server settings manually. When Outlook cannot configure the account automatically it will offer a manual setup option. The settings you will typically need are:
- \n
- Incoming mail server (IMAP): usually mail.yourdomain.com on port 993 with SSL \n\n\n
- Outgoing mail server (SMTP): usually mail.yourdomain.com on port 465 or 587 with SSL or STARTTLS \n\n\n
- Username: your full email address \n\n\n
- Password: your email account password \n
If you are unsure of the exact settings, your hosting provider’s support documentation or your IT team will be able to confirm them.
\n\n\n\nStep 3 — Wait for the Mailbox to Sync
\n\n\n\nOnce your account is connected, Outlook will begin downloading your emails from the server. For Microsoft 365 and Exchange accounts, Outlook by default syncs the last twelve months of email, though you can adjust this in account settings if you need more or less history. For a large mailbox with years of emails, this initial sync can take a considerable amount of time — anywhere from thirty minutes to several hours depending on the size of the mailbox and the speed of your internet connection.
\n\n\n\nYou can monitor progress by looking at the status bar at the very bottom of the Outlook window. It will show messages such as “Updating Inbox” or “Downloading messages” along with a progress indicator. Leave Outlook open during this process and avoid restarting your PC unnecessarily, as interrupting the sync can cause it to restart from the beginning. You can use Outlook while it syncs — newer emails will appear almost immediately — but some older items may not be available until the sync completes.
\n\n\n\nStep 4 — Bring Across Your Old Emails (PST Migration)
\n\n\n\nIf you have emails stored in local folders on your old PC — or if you have a PST file from a previous backup — you will need to import this into Outlook on the new machine. PST files are not synced to the server, so they will not appear automatically when you add your account. This is one of the most common reasons people think emails are missing after moving to a new PC.
\n\n\n\nTo import a PST file, copy it from your old PC to the new one first — a USB drive or network share works well for this. Then in Outlook go to File, then Open and Export, then Import/Export. For a full step-by-step walkthrough of the process including how to handle large files and what to do if the import stalls, see our guide on how to import a PST file into Outlook.
\n\n\n\nStep 5 — Recreate Your Email Signature
\n\n\n\nEmail signatures in Outlook are stored locally on each machine and are not synced through Microsoft 365 or Exchange. This means that when you set up Outlook on a new PC, your signature will not be there — you will need to recreate it. If you copied your signature text and any images from your old PC before setting up the new one, this is straightforward. If not, you may need to pull the text from a sent email or ask a colleague who received one of your emails to forward it back to you.
\n\n\n\nFor full instructions on setting up a professional signature including how to add images, links, and formatting, see our guide on how to create an email signature in Outlook.
\n\n\n\nStep 6 — Reinstall Your Add-ins
\n\n\n\nAdd-ins extend Outlook with extra functionality — CRM connectors such as HubSpot or Salesforce, grammar checkers like Grammarly, email tracking tools, meeting schedulers, and more. These are installed per-machine and do not follow your account when you move to a new PC. You will need to reinstall each one individually.
\n\n\n\nIf you made a note of your add-ins from the old machine before it was decommissioned, work through that list and reinstall each one. Add-ins are typically available either from the Microsoft AppSource store (accessible inside Outlook by going to the Home tab and clicking Get Add-ins) or as separate downloads from the vendor’s website. COM add-ins — the type that appear under COM Add-ins in File, Options, Add-ins — will usually need to be downloaded and installed as standalone applications rather than through the AppSource store. Make sure you have any licence keys or login credentials for paid add-ins ready before you start.
\n\n\n\nStep 7 — Check Your Rules and AutoComplete
\n\n\n\nOutlook rules — which automatically move, flag, or forward incoming messages — behave differently depending on your account type. If you are using a Microsoft 365 or Exchange account, server-side rules are stored on the Exchange server and will sync to your new PC automatically once your account is connected. Client-side rules, however, are stored locally and will not transfer. Open the Rules and Alerts window (Home tab, Rules, Manage Rules and Alerts) and check what has come across. Any rules that are listed as client-only will need to be recreated manually.
\n\n\n\nFor IMAP and POP accounts, all rules are client-side and stored locally, which means none of them will transfer to the new PC. You will need to set them up again from scratch.
\n\n\n\nThe AutoComplete cache — which provides email address suggestions as you type in the To field — is also stored locally. On your new PC it will start empty and gradually rebuild as you send emails. There is no easy way to transfer it directly, though third-party tools do exist if this is important to you. Most people find it rebuilds to a useful state within a few weeks of regular use.
\n\n\n\nCommon Problems After Setting Up Outlook on a New PC
\n\n\n\nEven when setup goes smoothly, a few issues crop up regularly in the days after moving to a new machine.
\n\n\n\n- \n
- Emails not syncing. If new emails are not appearing or your sent items are not updating, the most common causes are a disrupted connection to the mail server or a profile that needs to be repaired. See our full troubleshooting walkthrough on Outlook not syncing emails for step-by-step fixes. \n\n\n
- Profile errors on startup. If Outlook shows an error about the profile being corrupt or unable to open, try creating a new Outlook profile via Control Panel, Mail, Show Profiles and adding your account fresh into the new profile. \n\n\n
- Autodiscover failing. If Outlook cannot find the server settings automatically, check that your DNS is correctly configured and that your network is not blocking the autodiscover endpoint. Your IT team or mail host can verify this. You can also try entering the server settings manually as described in Step 2 above. \n\n\n
- Calendar not showing. If your calendar appointments are missing, check in the Calendar view that the correct calendar is checked on the left-hand panel. For Microsoft 365 accounts, the calendar syncs from the server in the same way as email, so it should appear once the initial sync completes. \n
Frequently Asked Questions
\n\n\n\nDoes Outlook transfer settings to a new PC automatically?
\n\n\n\nNot completely. Your emails, calendar, and contacts stored on Microsoft 365 or Exchange will sync to the new PC automatically once your account is connected. However, locally stored items such as your email signature, AutoComplete cache, client-side rules, and add-ins do not transfer and will need to be set up again manually on the new machine.
\n\n\n\nWill my folders still be there on the new PC?
\n\n\n\nFolders that exist within your mailbox on the server — including any folders you have created to organise your emails — will sync to the new PC along with your account. Local folders stored in a PST file on your old machine will not appear until you import that PST file as described in Step 4 above.
\n\n\n\nWhat if autodiscover fails when I try to add my account?
\n\n\n\nIf Outlook cannot automatically detect your server settings, you can configure the account manually. When the autodiscover attempt fails, Outlook will offer a link to set up the account manually. Click that link and enter the incoming and outgoing server details provided by your IT team or email hosting provider. Most web-hosted IMAP accounts use port 993 for incoming mail and port 587 or 465 for outgoing mail, both with SSL encryption.
\n\n\n\nDo I need to buy Outlook again for a new PC?
\n\n\n\nIf you have a Microsoft 365 subscription, your licence covers installation on multiple devices — typically up to five PCs and five mobile devices — so you can install Outlook on the new PC without any additional cost. Sign in at office.com with the same Microsoft account to download and activate it. If you purchased a one-time licence for a standalone version of Office, check the terms of that licence, as some one-time purchases are tied to a single device and may require a new purchase for the replacement PC.
