"Mail is not set up" or mail to my workspace is refused
An admin has not turned Mail on. Ask them to follow "Turn on Mail for your workspace (admins): short name, sender name, signature and rules". Until then, mail sent to your workspace's addresses is refused.

See "Mail needs a higher rank: why you see it and what an admin can do".
I cannot send to someone
You have run out of emails to new people for today. See "Mail sending limits: how many people you can email each day". People inside your workspace and people who already know you do not count.
Only inside the workspace is on. An admin has limited Mail to members and shared inboxes.
More than 20 recipients, too long, or a subject over 200 characters.
An attachment was blocked. Programs and scripts cannot be attached.
My email says "Not delivered" (newer Mail)
The other server rejected it: the address may not exist, or the mailbox is full. The reason is shown. Check the address and try again.
I am not receiving email
Check the Trash and Archive, and blocked senders and filters in Settings (a filter may have archived or trashed it).
An inbox gets at most 500 emails a day.
You may be below the lowest rank. Email still arrives, you just cannot see it until you are allowed.
The sender may have mistyped your address, which is
[email protected].
An attachment is missing
Incoming files over the space left in the inbox (100 MB) are left out and the email says so.
Dangerous files are removed, and the email says "The attachment x was removed".
A colleague emailed me but I cannot find it
Search the whole inbox (not just what is loaded). Use from: with their name or address.
I want to send an email later or cancel one
Use the arrow beside Send for Send later. Within 6 seconds of sending, use Undo. A scheduled email can be cancelled by opening it as a draft.
My signature looks wrong
An admin sets the signature. Placeholders (such as {rank} or {department}) come from your profile. If a detail is empty the line is left out. Ask an admin to check your profile.
Still stuck
Contact support from Help and Support, giving the address you used, roughly when, and what you saw.
