Editing Outlook email groups

Question

Editing Outlook email groups

Richard Sessions 0

I have an email group of fellow golfers that I need to update. It originally had 50 members and so I found that I could not add further members. I have now removed 3 members but it still won't allow me to add any more. What's wrong ?

1 -- Are you following the instructions in the "Add people to a contact list" section of this doc?

2 -- Do you get an error message when trying to add a new Contact to the List? If so, what was the error?

3 -- Are you using Outlook in a web browser ( https://outlook.cloud.microsoft/ ) or the New Outlook for Windows App?

Can you verify if this is the one that appears under Groups in Outlook?

Hi!

Welcome to the Microsoft Q&A forum.

There isn't a hard limit of exactly 50 members for a contact list, so removing 3 members should have allowed you to add 3 more.

Can you check your contact list and verify the removed members are actually gone. Save the list after removing the members. Remember to close the list and reopen it before adding a new ones.

You can try it and let me know if it works.

It's a Group, not a contact list. I have no problems with Contact Lists with over 50 names. It's a group that I can't add to.

Is this the error you see when trying to add a new member to your Group? If so, it can be caused by a number of events, including trying to add a new member who's email address is already assigned to another member of the Group.
