World Of Warcraft: Migration error due to game mail

Aeus from Blizzard Europe wants to let you know:

If you are currently trying to migrate a character and receive an error message because you are awaiting in-game mail, this is most likely due to the fact that you successfully completed one or several quests which result in an NPC sending you an item upon completion.

An example are some Argent Dawn quests, which result in a trigger for an item to be sent to you one week after you complete the quest.

The Argent Dawn quests are:

Note from the Front

Document from the Front

Letter from the Front

Missive from the Front

Page from the Front

Envelope from the Front

An example of two other, standard quests resulting in in-game mail:

Alas, Andorhal

Fruit of the Sea

If you are experiencing this issue please contact a Game Master via an in-game ticket and the Game Masters will attempt to assist you. Make sure to contact them as quickly as possible as they may need time to resolve it.

Alternatively, you have the option to use guild migration assistance. For more information please check this post

And remember: if you are planning to migrate in the near future please make sure not to complete quests that will result in an in-game mail being sent to you.
