Are you considering your business email strategy and whether to stay with the Microsoft Exchange email Server on-premises or move the email server to Exchange Online in Microsoft Office 365? You are not alone. Statistics show that on-premises email server adoption by publicly listed companies is still just under 20%, but is gaining significant traction. Microsoft offers Exchange Online plans 1 and 2 for Office 365 Exchange Online.
Email Server to Exchange Online – We offer you a plan to migrate your on-premises Exchange server to Exchange Online, Office 365. Server consultancy has gained In-depth knowledge and experience by migrating thousands of mailboxes from on-premises Exchange servers to Office 365 Exchange Online, including Mailboxes, Groups, Public folders, and contacts. We carefully perform all the tasks, from discovering your existing Exchange server to planning the migration and performing all the post-migration tasks once the email server migration to Exchange Online is completed.
Microsoft migration batch, available in the Office 365 portal, is a powerful tool that is free with your Office 365 subscription. It supports three types of online migration methods for Exchange.
Cutover Email server to Exchange Online Migration
A cutover migration uses Microsoft Exchange Server 2003 or later, and is suitable if you have fewer than 2000 mailboxes. This migration method means you can move your entire email server to Exchange Online over a few days, and Server Consultancy can manage all accounts in Office 365. Although you can migrate 2000 mailboxes, Server Consultancy suggests only moving 150 to minimise downtime. A seamless cutover migration does not impact users except for delays in new email routing until the MX record is changed.
Staged Email server to Exchange Online Migration
You can choose this type of migration if Microsoft Exchange version 2003 or 2007 has more than 2000 mailboxes. For a staged migration to work, you must synchronise accounts between your on-premises Active Directory domain and Office 365. The email server used to migrate to Exchange Online uses the Azure Active Directory sync. AD Connect synchronises your on-premises Windows Active Directory to Azure AD, allowing you to password synchronise across AD & work as a single sign-on.
Hybrid Email server to Exchange Online Migration
Use this migration type to maintain on-premises and online mailboxes for your business. This method allows companies to migrate employees and emails to Exchange Online in Microsoft Office 365. Server Consultancy recommends that firms use this method if they have Microsoft Exchange 2010 or 2013 and more than 150 – 2000 mailboxes and want to gradually move them in small batches.

Suppose you are a business with an on-premises Exchange Server or a Microsoft small business server environment. In that case, Server Consultancy can help you migrate your on-premises Exchange data, including emails, groups, calendars and contacts for user mailboxes, to Office 365.
Other research shows that over 80% of businesses have adopted the cloud for at least one of their business applications. However, letting go of their legacy or hosted email system remains challenging for some companies.
With Microsoft Exchange Online holding the market share for business email, we looked at the differences between on-premises Microsoft Exchange Server and Office 365.
What are the POP Office 365 Exchange server settings?
POP (Post Office Protocol) is one way to access your Office 365 emails, although it’s not recommended for most modern business setups due to its limited sync capabilities.
If you need to use POP, here are the basic settings:
Server name: outlook.office365.com
Port: 995
Encryption method: SSL/TLS
POP does not sync folders, sent items, or calendar data, making it far less efficient than Exchange. If you still rely on outdated protocols, it may be time to switch to Exchange Online. Server Consultancy, London’s best IT support company, can help you migrate smoothly and securely with zero data loss.
What is the IMAP server for Office 365 Exchange?
Unlike POP, IMAP (Internet Message Access Protocol) lets you access email from multiple devices and keeps everything synced. It’s a better choice for users who are not ready for the whole Exchange experience.
Here are the typical settings:
IMAP server: outlook.office365.com
Port: 993
Encryption method: SSL/TLS
While IMAP is a step up from POP, moving to Exchange Online provides better integration with Outlook, shared calendars, contacts, and compliance features. If you plan to move from any legacy system, Server Consultancy can provide expert support through your Email Server to Exchange Online transition.
What are the Microsoft Exchange SMTP server and port?
SMTP (Simple Mail Transfer Protocol) sends emails from your client or application. To set it up for Office 365:
SMTP server: smtp.office365.com
Port: 587
Encryption: STARTTLS (or TLS if required by your client)
Authentication: Required (use your Office 365 login credentials)
Configuring your email for secure sending is just one part of a successful setup. If you’re integrating with third-party services or migrating from an on-prem email platform, Server Consultancy—the best IT support company in London—can handle everything from SMTP setup to complete migration to Exchange Online.
How do I move emails to Exchange Online?
Moving from an old email system to Exchange Online can feel like a big step, but it doesn’t have to be complicated with the right plan.
Start by reviewing your current setup—whether it’s an on-prem Exchange server, POP, IMAP, or a third-party provider like Gmail.
Choose the migration method that suits your business best:
-Cutover Migration – great for smaller teams wanting a one-time switch
-Staged Migration – ideal for phased transitions from older Exchange servers
-Hybrid Migration – perfect for keeping some mailboxes on-prem and others in the cloud
-IMAP or PST import – helpful when moving from non-Exchange platforms
Prepare your Microsoft 365 environment by:
-Setting up user accounts and assigning licenses
-Configuring domains and DNS records
-Ensuring email flow is correctly routed
Always back up your existing mailboxes before the move, just in case.
-Work migration using tools like Microsoft’s Exchange Admin Centre or PowerShell scripts.
-Test everything—emails, folders, calendars, contacts, and mobile access—before switching.
Update DNS records and decommission old systems if needed.
With a process like this, the details matter. That’s why many London businesses trust Server Consultancy—the best IT support company in London—to manage their Email Server to Exchange Online migrations. We ensure everything runs smoothly, securely, and without disrupting your team.
How do you find the Exchange server name in Outlook 365?
Outlook with Microsoft 365 doesn’t show a traditional “server name” like older setups. That’s because Exchange Online uses auto-discovery to connect your account without needing manual settings. But if you do need to confirm the connection:
Go to File > Account Settings > Account Settings
Select your email and click Change
You’ll see outlook.office365.com listed as the server in most cases
If you’re managing multiple users or migrating from older systems and need clarity on server roles or routing, Server Consultancy can help you audit and optimise your setup. With our Email Server to Exchange Online expertise, everything works exactly as it should—no guesswork, no stress.
