Google is investigating a service outage affecting Gmail users worldwide that causes issues when syncing emails with Microsoft servers via the Internet Message Access Protocol (IMAP).
On affected devices, Gmail users say they’re not receiving emails and that they’re also having issues syncing their Hotmail accounts.
Impacted customers report seeing “There was a problem while syncing this folder. Please try again later.” errors.
“I have not been able to sync my Hotmail account in the Gmail app for the last few days, my outlook account is syncing fine it is only the Gmail app that this isn’t working! I have tried everything to resolve this issue but nothing is working,” another user said.
Additional reports also point at the Gmail mobile app being the one affected by these ongoing sync issues, with desktop apps working as expected.
