This happens every time I try to save to the cloud: "Can't open file. The account you signed in with." Stable wifi, original account, no multiple logins, re-logged, restarted Mac, Illustrator 2026. I am the file owner.

1. Force-reset Adobe’s cloud identity cache (most common fix)

Even if you’re logged in correctly, Illustrator can be holding on to a corrupted token.

Do this exactly:

1. Quit Illustrator

2. Quit Creative Cloud Desktop

3. In Finder → Go → Go to Folder…

4. Paste:

   ~/Library/Application Support/Adobe/

5. Delete these folders (or rename them if you’re cautious):

   • Creative Cloud

   • OOBE

   • AdobeSync

6. Restart your Mac

7. Open Creative Cloud Desktop

8. Sign in again

9. Open Illustrator → try saving to Cloud

🔹 This fixes ~70% of cases like yours.

2. Check which Adobe account Illustrator thinks you’re using

This error often happens when Adobe silently flips between:

• Personal account

• Enterprise / school / work account

In Illustrator:

• Help → Sign Out

• Quit Illustrator

• Open Creative Cloud Desktop

• Click your profile photo → Account

• Confirm you’re logged into the same account that owns the file

• Open Illustrator again

⚠️ Even if the email is the same, Adobe treats these as different identities.

3. Cloud Documents sync itself may be stuck

Illustrator Cloud Docs rely on a background sync process that can silently fail.

Try this:

1. Open Creative Cloud Desktop

2. Go to Files

3. If you see:

   • “Sync paused”

   • “Syncing…” stuck forever
     → Toggle sync off, wait 30 seconds, toggle on

Then try saving again.

4. Test by duplicating the file locally first

Sometimes the file’s cloud metadata is broken.

1. File → Save a Copy

2. Save it locally (Desktop)

3. Close the original cloud version

4. Open the local copy

5. File → Save to Cloud Documents

If this works, the original cloud file is corrupted (sadly common).

5. Last resort (but reliable): move the file out of Cloud Docs entirely

If you’re blocked and need to work now:

• Save locally

• Work locally

• Upload to cloud later from Creative Cloud Desktop → Files

Not ideal, but it avoids data loss.
