Multiple Exchange accounts merge data in Microsoft Entourage
We do not recommend setting up multiple Exchange accounts within the same identity in Microsoft Entourage v.X or 2004. If you do, you will end up merging data such as the calendars and address books between the two accounts. (However, mail data such as inboxes and other folders should remain separate.) Entourage is unable to keep the calendar and address book data separate between two Exchange accounts. A future revision of Entourage may allow this.
If you need to use multiple Exchange accounts in the meantime, we suggest:
- In the same Mac OS X user account and Entourage identity: set up your main Exchange account normally, and then use Delegate access in Microsoft Entourage 2004 for any additional accounts. You will be able to use the data in the additional accounts and act as if you were logged into each account, but the data will not be merged on the Exchange server.
- In the same Mac OS X user account: use two different identities within Erage, and then use the "Switch Identity" command in the "Entourage" menu to switch between them.
- In separate Mac OS X user accounts: if you can create two or more Mac OS X user accounts, you can set up Entourage separately in each one. This may be most helpful if you are using Mac OS X 10.3 or later, so that you can use "Mac OS X Fast User Switching".
Recovery from merged data
ITS is unable to assist with recovering the pre-merge state of two Exchange accounts. The only way to unmerge the accounts is to:
- Remove the second account from the single Entourage identity
- Manually delete the calendar events and address book contacts that should not be in each individual Exchange account.
If you do not remove the additional Exchange accounts from the accounts list in Entourage, the data will just be re-merged. You must separate the accounts -- before removing the merged data -- into other identities, set up delegate access, or use individual Mac OS X user accounts.
