Maintenance for the week of February 16:
• [COMPLETE] ESO Store and Account System for maintenance – February 19, 9:00AM EST (14:00 UTC) - 6:00PM EST (23:00 UTC)
Today I received some items that had expired in guild store listings. I took the attachments then tried to delete the empty messages, but pressing X then E had no effect. The messages remained in the inbox list.
I had used reloadui and traveled to other zones without resolving the problem. When I logged in another character I was able to delete the empty messages with no problems.
