Using Multiple Exchange Accounts In Outlook

How many Exchange accounts do you manage? Is there a way to deal with all of them at the same time? If so, you’ll need Microsoft Outlook. You can connect several Exchange accounts to Outlook. As a result, you may access all of your account’s email functions at the same time, eliminating the need to switch between them. You’ll also get quick access to any of your commonly used accounts’ folders or files.

By default, Outlook allows a maximum of 10 Exchange accounts to be set up in one mail profile. This is more than enough for most users, but if you need to add more accounts, it can be done by modifying the account settings in Outlook to Registry tweak. You can find more information on Outlook Transfer website about this and other features.

To create and configure additional Exchange accounts in Outlook it is necessary to create a Registry value:

  1. Open the Registry Editor by pressing the Windows key + R then typing “regedit” 
  2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Outlook\Profiles
  3. Select “New” and create a DWORD value called “maxnumexchange”
  4. Add the following value type: REG_DWORD

You can now launch Outlook and create additional Exchange accounts up to the maximum set in the Registry. Be sure to save your changes before closing the Registry Editor and launching Outlook.

Synchronize Your Exchange Accounts

If you work for two companies (A and B), you probably have two Exchange Server accounts as well. Your email messages, contacts, calendars, tasks, and notes are different in these two accounts. Having to check your calendar for available time slots can be repetitive and time-consuming. If you’re someone who has multiple jobs or clientele, then you know how tough it can be to keep track of everything.

This article will cover four approaches to Exchange Server synchronization.

One-Way Migration From A To B

If you need to move items from one server to another, the best method is a one-way migration. This means that all of your email messages, contacts, calendars, tasks, and notes will be transferred from account A to account B. You can use an Outlook Add-in or third-party software to automate this process.

Two-Way Synchronization

If you want to keep your accounts in sync, the best option is two-way synchronization. This means that all of your mail items (messages, contacts, etc.) will be updated on both servers at once. You can use an Outlook Add-in or third-party software to automate this process.

Synchronization On Mobile Devices Via Exchange ActiveSync

Another option is to synchronize multiple accounts on a mobile device via Exchange ActiveSync. This allows you to keep your important emails, contacts, calendars, tasks, and notes in sync across all of your devices.

With the right tools, you can easily keep your accounts organized, up-to-date, and synchronized across all of your devices.
