Number of Exchange Accounts Limit in Outlook

with No Comments

By default the number of Exchange Accounts Limit in Outlook 2010 and Outlook 2013 is set at 10 Exchange accounts for a single Outlook mail profile.

In most cases this is sufficient although we have had a few customers ask us to increase the number of Exchange Accounts limit in Outlook in the past.  This could be for many reasons, for example some Directors of companies may want to see all the departmental mailboxes (sales@, info@) as well as their staff mailboxes in order to keep track of what is being sent in and out from their company.

Anyway the Exchange Accounts Limit in Outlook can easily be fixed by making the following change in the Windows Registry, please see below;

 

How to Increase the number of Exchange Accounts limit in Outlook

To increase the limit to up to 9999 Exchange accounts, the following Registry value needs to be created.

Here is step by step instructions on how to open the Windows registry and to make the relevant changes;

  • Click the Start button which is located on the bottom left of your screen.
  • In the Start Menu, type regedit and press Enter.
  • If prompted by User Account Control, click Yes to open the Registry Editor.
  • The Windows Registry Editor window should open and it will look similar to the example shown below.

  • Enter MaxNumExchange, and then press the Enter key.
  • In the Details pane, press and hold (or right-click) MaxNumExchange, and then select Modify.

As with all Registry changes a reboot will be required to take effect.
