Mail merges allow a user to send personalized emails simultaneously to a group of recipients from a shared email account. The personalized information is usually stored in Excel or database, merged into a specially prepared Word document, and sent from Outlook. Outlook works best when we create a separate Outlook profile for mail merging. A mail merge-specific Outlook profile should only contain the shared mailbox used in the mail merged communications.
Now when Outlook opens, it will ask the user to select a profile. Choose the default Outlook profile for normal use; choose the new mail merge profile for mail merging.
