There is a message showing:

> You’re out of storage space and will **soon** be unable to send or receive emails until you [free up space][1] or [purchase additional storage][2].


at the top of Gmail's page, as such:

How long is "soon"? Within how many days must we react?

 Is there more information (*"storage limit algorithm"*) regarding this issue?


Can we expect Gmail-drive to continue working while *"out of storage"* for  **31 days** or even twice of that duration?

&bull; Currently Gmail is still able to send and receive emails seemingly perfectly, even with attachments (tested with *random* file [JMeter 2.8][4], 26,172,552 bytes). (Note that the .zip file extension [needs to be renamed][5] before sending.)
</sup>

<sup>
&bull; [`google.com/settings/storage`][6] is showing:

&nbsp;&nbsp;[![enter image description here][7]][7]

&nbsp;&nbsp;And subscription payment has an error: https://i.sstatic.net/8w3D3.png.

<sup>
&bull; Gdrive is working fine too. Downloads are working as per normal, but uploads will show "Quota exceeded" message.
