<b>The numbering in Column A</b> (so far manually) <b>should be automated</b>. <br />
<br />
The macro or formula is to count the number of occurrences of the e-mail adresses in Column A as depicted in the screenshot above. <br />
<br />
- Single e-mail addresses get the number <b>1</b><br />
- Multiple occurrences of e-mail addresses get <b>1 to n</b> numbering depending on the number of occurrences of the respective e-mail address. <br />
<br />
I have attached a sample file for your convenience. <br />

Help is very much appreciated. Thank you very much in advance. <br />

Sequentially number occurrences of e-mail addresses using a formula or VBA

Microsoft Office is an integrated suite of applications that includes Outlook, Word, Excel, Access, PowerPoint, Visio and InfoPath, along with a number of tools to assist in making the individual components work together. Coding within and between the projects is done in Visual Basic for Applications, known as VBA.

Microsoft Office

Microsoft Excel topics include formulas, formatting, VBA macros and user-defined functions, and everything else related to the spreadsheet user interface, including error messages.

Microsoft Excel

Microsoft applications include a variety of software programs, including development and digital authoring programs (Expression and Media Center), educational programs, Internet software, including Essentials, Skype and the Live family, anti-virus, productivity applications and suites like Office, Excel, Word, Outlook, Access and PowerPoint, video games and server applications such as Exchange, SharePoint, IIS and Virtual Server.

Microsoft Applications

Visual Basic for Applications (VBA) enables building user-defined functions (UDFs), automating processes and accessing Windows API and other low-level functionality through dynamic-link libraries (DLLs). VBA is closely related to Visual Basic and uses the Visual Basic Runtime Library, but it can normally only run code within a host application rather than as a standalone program. It can, however, be used to control one application from another via OLE Automation. VBA is built into most Microsoft Office applications.
