Groupmailbox with many delegates

Hello all,

I have an issue with a mailbox that has 206 delegates. On the archive (using permissionbrowser) I see many, but not all. This results in not all delegates having access to the archive of that groupmailbox.

I believe I have seen this before (ie a limit on the amount of delegates) but I cannot find related information. If anyone knows if there is a limit, please let me know.

I was thinking to create a group that has these 206 people in it, and then assigning the group the necessary delegation rights on the mailbox. As far as I know there are no caveats (as long as it is not a group in a group in a group), but I am not sure.

Delegating the group should work as far as I know. Can any of you confirm this?

Thanks,

Gertjan
