Some Gmail for iOS users just received an important notice from Google urging them to check their trash and spam folders for wrongly-categorized emails.

According to the Gmail team, some users were affected by a bug that saw trash and report spam actions taken on some messages actually affect other messages. That means that some users may have hit delete on Email A, but actually had Email B or C moved to the trash without their knowledge.

The bug apparently affected messages received the week of January 15th to the 22nd.

Here’s the notice that some users received (h/t The Verge):

You may have been impacted by a recent issue in Gmail that inadvertently caused some actions (e.g. delete, report spam) taken while viewing a message to be applied to a different message. The issue occurred between January 15 and January 22 and is now fixed.

We encourage you to check your Trash and spam folders before February 14, 2014 for any items you did not intend to delete of mark as spam and move them back to your inbox. We apologize for any inconvenience.

It’s good the the issue has been resolved, but accidentally-trashed emails could have been the cause of some major headaches over the past couple of weeks.

As you may recall, Gmail and Google+ were hit with a major outage earlier this week. The outage lasted for about 30 minutes and Google is blaming it a bug that caused an internal system to generate and incorrect configuration.
