User has does not have permission to be mentioned

Question

We have a TFS user who appears to have the same permissions as a colleague in their team. However this user can't be @mentioned despite having the ability to open and close and otherwise edit the bug that they can't be mentioned in.

The following error is emailed to me following attempting to @mention this user.

@Joe Bloggs cannot be mentioned in the Bug 41729. The user does not have sufficient permissions.

We can't see any differences between a user that can be tagged and one that can't.

Answer 1

We were getting this same error.

• Went into the project settings -> security.
• Clicked "remove" on that user
• at which point the "remove" changed into an "undo".
• Clicked the "undo".

Now we are no longer seeing this error. Seems like something internally just needed to be recombobulated :-)
