Advice and answers from the Astro Team

The very first time you sync your inbox in Astro will sometimes take a bit longer than a normal sync.

How long it takes depends on the size of the inbox you're syncing, and can be as fast as a few minutes for a small inbox, or up to 2-6 hours for a very large inbox. 

Only the first sync takes this long, and afterwards your email sync and stay up to date in seconds.

Experiencing issue syncing?

  • Check our status page for updates about Astro downtime and performance issues.
  • Try resetting and reauthenticating your account, which will resync your emails: macOS: Go to the Astro menu (top left in tool bar) > Preferences > Accounts, and select the Reset Account button (see screenshot below).
    iOS:
    Go to settings, tap the email address with syncing issues under accounts, and select "Reauthenticate Account" under Debug towards the bottom of the screen
