Synchronization issue in New Outlook for Mac – ״Failed to refresh subscriptions.״
Hello, I am using Microsoft 365 (Exchange Online) on Mac, running macOS 26.1 (Tahoe). My Outlook client is: Outlook for Mac Version 16.103.3 (25113013), with a Microsoft 365 Subscription license. Since yesterday morning, in the New Outlook interface, my inbox has suddenly appeared empty, and I constantly receive the following error message: “Failed to refresh subscriptions.” It’s important to note: In Legacy Outlook, everything works perfectly. The web version and the Outlook app on my mobile phone also work well. The issue persists regardless of the network I am on (home, office, cellular, etc.). Troubleshooting steps I already tried: • Updating Outlook to the latest version • Removing and re‑adding the account • Clearing cache and preferences • Formatting my Mac and reinstalling everything from scratch Unfortunately, none of these steps has resolved the issue. Is this a known bug, and is there a recommended workaround or an upcoming fix? Appreciate assistance on that issue.
MAC - Importing Legacy POP On My Computer data
The end is nigh for Legacy thus I did the switch as a test knowing I could still revert. Background: I have long time POP account. In the UBF8T346G9.Office, Outlook, Outlook 15 Profiles, Main Profile: Data folder: 159 GB. Largest folders: Message Attachments: 90 GB Message Sources: 65 GB Messages: 5 GB Before I switching I tried: Export Data to OLM – don't have enough room Delete attachments from multiple emails – can only do one email at a time. Rules can't help After switch it began importing On My Computer data which was hopeful, but it held at 141498 items, and would take days I read. I reverted back to Legacy and will go another way about it when I have a few off days. My question: Apart from deleting years of emails, what's a better way to get the most data out of Legacy, and/or speeding up the import? Get another drive and Export Data to OLM, then manually import? Delete attachment folders directly from Message Attachments folder? Find something like Clean my Mac? ?? Perfect world I get all my in out mail with whatever attachments remain and Calendar data, but I'll take what I can get at this point. Appreciated!
Outlook IMAP in PHP
I'm trying to retrieve inbox mail using IMAP, but I'm encountering the following error. I've attached the code and error details below. Please advise. $imapServer = "{outlook.office365.com:993/imap/ssl/novalidate-cert}INBOX"; $username = '*************'; $password = '*************'; // Use an App Password for security $imapStream = imap_open($imapServer, $username, $password, OP_READONLY, 0, ['DISABLE_AUTHENTICATOR' => 'GSSAPI']); I'm getting this error: A PHP Error was encountered Severity: Warning Message: imap_open(): Couldn't open stream {outlook.office365.com:993/imap/ssl/novalidate-cert}INBOX Filename: controllers/Cron_Controller.php Line Number: 39 Backtrace: File: C:\xampp73\htdocs\WPS2.0_2025_03_04_1847\application\controllers\Cron_Controller.php Line: 39 Function: imap_open File: C:\xampp73\htdocs\WPS2.0_2025_03_04_1847\index.php Line: 348 Function: require_once A PHP Error was encountered Severity: Notice Message: Unknown: LOGIN failed.

View Group membership in outlook app for any user
Earlier version of Outlook Desktop application use to provide Group / DL membership information of any user, within the user property window opened from the Address Book or from any email. But the latest version of Outlook Windows app as well as the Outlook Webapp for Microsoft 365 no longer provide this Group / DL membership info within the User property. Does this require some configuration change at the Admin level (https://learn.microsoft.com/en-us/microsoft-365/enterprise/manage-microsoft-365-groups-with-powershell?view=o365-worldwide#hide-microsoft-365-groups-from-the-global-address-list) ? OR Is there an alternate option available within the new Outlook Windows app to view the Group / DL membership of any user?
