Gmail users are finding these emails are being lost by Windows 10 / GETTY IMAGES

Reported by both Windows Latest and MSPowerUser, Gmail users are discovering that Microsoft’s Windows 10 built-in Mail client is deleting their emails and/or sending them to spam automatically. One user described their experience:

“I have been facing an issue with the Windows 10 Mail app linked to a Google account. I have noticed that when I respond to emails, the email I send disappears and cannot be found in sent items, outbox, bin, spam, or anywhere actually. The disappeared email cannot be found on gmail's web interface either. It appears that it is automatically deleted and erased from the server.”

06/27 Update: according to several posters, Google has confirmed this is a Microsoft problem rather than Gmail which means users will have to wait for a Windows 10 update rather than a Googles server-side tweak. In addition to the workarounds detailed below, an additional temporary fix has been found:

• Gmail.com > Settings > Filters and blocked addresses > Create a new filter
• In 'From' field enter your address
• Click 'Create filter'
• On the next page, select 'Never send it to Spam'
• Click 'Create filter'

This workaround isn't perfect because it creates two sent items in Windows Mail but it does stop Gmail emails being lost or deleted which is the most important, thing until Microsoft comes up with a fix. “The latest version of Windows Mail has broken the settings for Gmail,” confirmed a Windows Insider MVP. Stating that the only workarounds are to either a) remove your Gmail account from the Mail app and weaken the security settings in Gmail by allowing access to less secure apps (guide), or b) remove your account and use Gmail’s manual IMAP settings (guide).

If you are lucky, you may be able to recover some of your lost email from spam afterwards.
So what has caused this potentially damaging problem? Most fingers currently point at the troubled Windows 10 May 2020 Update (surprise, surprise), though by no means all.

As it stands, Microsoft has not acknowledged the problem and it remains an ongoing cause of concern for all Gmail users who access their email via the Windows 10 Mail app. I have contacted Microsoft and Google about this and will update the post when I know more.
