Using older versions of Outlook for Mac for personal email and calendar
If more storage was just added, the mailbox and cloud storage status can take time to update across the account. Reported cases in the provided context indicate the new storage can appear within about 2 hours, while send/receive blocks can take 24 hours and in some cases up to 48 hours to clear.
While waiting, check these items:
- Verify storage status in Outlook.com:
- Open Outlook.com Settings and search for Storage.
- Check both mailbox usage and what is consuming space.
- Check Microsoft cloud storage, not just mailbox storage:
- If Microsoft cloud storage is full, Outlook.com cannot send or receive email even if the mailbox itself is not full.
- Cloud storage includes OneDrive files, OneDrive Recycle Bin, Outlook.com attachments and inline images, Teams attachments, and more.
- Free up space if still over quota:
- Delete large emails and attachments.
- Empty Deleted Items because it still counts toward mailbox quota until manually emptied.
- Empty the OneDrive Recycle Bin.
- In Outlook.com, messages sent while storage was full are bounced back to the sender and must be resent after the account is back under quota.
- Check for common send issues:
- Look in Drafts or Outbox for stuck messages.
- If an attachment is larger than 25 MB, remove it and send a smaller attachment or upload it to OneDrive and send a link instead.
- If using Outlook on Mac with the Outlook.com account:
- Try the same account in Outlook.com on the web first. If web mail also cannot send or receive, the issue is with account storage status rather than the Mac.
If the storage upgrade still has not taken effect after 24 to 48 hours, use Outlook.com support from the Help menu in Outlook.com and select Still need help? if the self-help steps do not resolve it.
