QuickMail talks to your accounts for three kinds of information — mail, contacts, and calendar — and it treats each one differently. Everything else QuickMail knows about is stored on this computer and never leaves it.
The direction matters, so it is worth being blunt about it: a two-way item is safe to change in QuickMail, and the change reaches your account and every other program you read mail with. A download only item is a copy — changing it in QuickMail either is not offered, or would be undone the next time QuickMail refreshed. This computer only means exactly that: reinstall Windows or move to a second machine and you start over.
| What | Direction | What that means for you |
|---|---|---|
| Messages | Two-way | Read and unread, moving between folders, deleting, and sending all go to the server. Another program sees the same state. POP3 accounts are the exception — the protocol has nowhere to record any of it, so everything but sending stays on this computer. See POP3 accounts. |
| The built-in flag | Two-way | Set or cleared in QuickMail, it shows up everywhere else, and a message flagged elsewhere arrives here already flagged. |
| Named flags you create | This computer only | The name and color exist in QuickMail alone. Other programs, and QuickMail on another computer, will not see them. |
| Contacts | Download only | QuickMail reads your Microsoft, Google, and iCloud contacts and never writes back. Synced contacts cannot be edited or deleted in the address book — make the change at the account and re-sync. |
| Calendar events | Mostly two-way | Single (non-repeating) events on a connected calendar can be created, edited, and deleted from QuickMail. Repeating events, meeting invitations, and the events your provider manages for you are download only. |
| Meeting responses | Two-way | Accept, Tentative, and Decline are emailed to the organizer and update your calendar. |
| Mail rules | This computer only | Rules run inside QuickMail as mail arrives. They are not server rules — your provider does not know about them, and they do nothing while QuickMail is closed. |
| Everything else in QuickMail | This computer only | Settings, themes, keyboard customizations, signatures, message templates, saved views, message-list field choices, contact groups, and the contacts you typed in yourself. |
That is nearly always a download-only item. QuickMail refreshed from the account, the account still had the old version, and the old version won. The fix is the same in every case: make the change where the item actually lives — your account’s own contacts or calendar on the web — and then refresh QuickMail (Sync Now in the address book, F5 in the calendar).
Your mail, your contacts, and your connected calendars come back on
their own once you add your accounts again, because they live on the
server. The This computer only row above does not:
rules, flags you named, templates, signatures, saved views, and your
settings are stored in QuickMail’s data folder
(%APPDATA%\QuickMail) and need to be copied across if you
want them.
A POP3 account is the exception
to the first sentence. If it is set to remove mail from the
server once collected, the server has nothing left to give back and
mail.db in that data folder is your mail — copy it across,
or back it up, like any other document.
