Frustrating! The new update has logged me out - and I cant get back in, Mac!
The new update has taken me back to outlook legacy, logged me out of all my emails! and I cant get back in. I try to switch back to the new interface and get a notification to say i am offline, to which I try to log back in, but I get another message to say my relevant emails hold no subscription. it takes me to the subscription page where I keep getting an error message that says something has gone wrong! The actual email I am trying to log into is IMAP - so I assume I need to log in with a genuine outlook email address first, which I have tried but get the notification to say I hold no subscriptions. I have installed and re-downloaded but still no luck! Please help!
Outlook emails are not syncing on macOS
I have been experiencing several synchronization issues with Outlook for Mac when using my IMAP email account. My environment: macOS 26.6.2 Outlook for Mac 16.112.3 Microsoft 365 subscription First, emails that I delete from my Inbox sometimes reappear several minutes later. In addition, I have confirmed with my IT support team that incoming emails are successfully delivered to my IMAP mailbox. However, Outlook often fails to synchronize and display those messages. Even when I manually initiate a sync, the missing emails do not appear. I do not understand why the synchronization is so unreliable. I have already reviewed several online articles and troubleshooting suggestions, but none have resolved the issue. 1.Update Microsoft 365 or Office on macOS: https://support.microsoft.com/en-us/office/lifecycle/officeinstall/update-m365-office-macos-ios 2.Clear the cache in Outlook for Mac https://support.microsoft.com/en-us/outlook/clear-the-cache-in-outlook-for-mac 3.Repair Outlook Data Files (.pst and .ost) https://support.microsoft.com/en-us/outlook/repair-outlook-data-files-pst-and-ost 4.Outlook for Mac – Email Synchronization Troubleshooting https://learn.microsoft.com/en-us/answers/questions/6003894/outlook-for-mac-legacy-outlook-not-syncing-one-ema Has anyone experienced similar behavior with Outlook for Mac and IMAP accounts? Any assistance or recommendations would be greatly appreciated. Thank you very much for your help.
No New Folder Creation?
I'm in Mac Outlook 16.112, using Legacy view. I'm trying to add a new sub folder and that option is disabled on every right click menu I can find, and doesn't appear in any ribbon menu. What is going on? I have quite a few subfolders, all created using the right-click option. Why is that suddenly unavailable? This is incredibly frustrating. -Monica Sandler Director of Customer Success EstateWorks SystemsThousands of Sent Items moved to Deleted Items, no rules, no retention
Hello everyone, I'm investigating a very unusual Exchange Online mailbox issue and would appreciate any insights from anyone who has seen something similar. Environment Exchange Online (Microsoft 365) Mailbox: User mailbox Outlook for Mac Outlook for iOS Outlook Web (OWA) Incident Summary On August 13, 2026, approximately 4,997 messages were moved from: The activity occurred over roughly a 3-hour period. Mailbox audit logs show thousands of: Operation: MoveToDeletedItems events. Hourly breakdown: 01:00 - 2,046 events 02:00 - 1,540 events 03:00 - 1,408 events Audit Findings All sampled audit events show: LogonType = 0 (Owner) UserId = affected mailbox owner Result = Succeeded I sampled 5,000 records and all of them were: LogonType = 0 No events were recorded as: LogonType = 1 (Admin) LogonType = 2 (Delegate) Source and Destination Folders Examples from mailbox audit records: Folder : \Sent Items Destination : \Deleted Items Operation : MoveToDeletedItems Message Trace Findings Extended Message Trace was performed on one of the affected emails. The trace confirmed: CopiedToSentItems=True DeleteAfterSubmit=False which indicates: The email was successfully sent. The email was copied to Sent Items. Exchange did not delete the message during transport. So the message existed in Sent Items and was later moved to Deleted Items by a mailbox operation. Rules Investigation Checked: Get-InboxRule -Mailbox <mailbox> -IncludeHidden Findings: No Inbox Rules targeting Sent Items. No hidden Inbox Rules targeting Sent Items. Only two legitimate rules that delete messages from specific Jira/Confluence senders. Delegation Investigation Mailbox permissions reviewed. Known permissions exist, but mailbox audit logs show: 5000/5000 sampled events = LogonType 0 Therefore: No evidence of delegate activity. No evidence of administrative activity. Retention / Compliance Investigation Checked: Get-Mailbox Get-RetentionPolicy Get-RetentionPolicyTag Get-RetentionCompliancePolicy Get-RetentionComplianceRule Findings: No Sent Items retention tag. No retention policy targeting Sent Items. No Purview retention/compliance policy appears to explain this behavior. Activity pattern does not resemble normal retention processing. Add-ins Investigation Mailbox add-ins: Polls Share to Teams Send to OneNote Action Items Bing Maps My Templates Unsubscribe No third-party mailbox-management or archiving add-ins found.

Unable to drag cursor to select text in a draft.
For as long as I can remember, I have been unable to drag my cursor to select any text in a draft message. I can however drag the cursor to select text in a received message, as long as I'm not in the midst of drafting a response. I can use a combination of SHIFT+ arrow keys to select text. I also have no issue dragging the cursor to select text in Outlook on the Web. I have to assume this is intentional being that this bug has existed for so long. Is there any explanation as to why Microsoft feels Outlook for Mac users should not be permitted to drag their cursor to select text? I've just updated Outlook for Mac via the App Store to version 16.83 (24031120).
Signature displayed wrong in New Outlook on Mac
When creating a new e-mail, my signature is displayed in Times New Roman (?) instead of the default font. In the Signature editor, the display is correct. In Sent, the mail is displayed correctly as well. Signature editor: New email: Outlook version: 16.110 Mac M4 Mac OS 26.5.1
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!Attachments to calendar events
I have outlook version 16.106.1 and for some reason the attach file icon is not active. Can I get some advice on how I can activate this so I can add attachments to events I schedule in my calendar. I don't seem to be able to even copy over emails to scheduled events. Any advice appreciated.New Outlook: Calendar view cannot open modal dialogs (e.g. new event/settings) – Mail view works
I've been troubleshooting the above new issue (to me) with Copilot to produce the below summary. Hope this is helpful and you can advise and/or resolve ASAP! Thanks. --- We are experiencing a consistent issue in New Outlook for Windows, with similar reports from Outlook for Mac, where Calendar view fails to display modal dialogs. This affects: Creating new calendar events Editing or duplicating events Opening Settings When triggered from Calendar view, no dialog appears and the UI becomes unresponsive for that action. Note: Once calendar view 'breaks' Outlook, even switching back to mail view doesn't always work (incl. inability to close via usual X top right). Key behaviour ✅ Issue occurs only in Calendar view ✅ Same functionality works correctly from Mail view: New → Event opens and works Settings opens normally ✅ Outlook Web (PWA) and Teams Calendar work without issue ✅ Switching from Calendar → Mail immediately restores functionality Impact Users cannot effectively manage calendars using the desktop app (only view) Disrupts scheduling workflows Requires switching views or using other apps to complete basic actions Scope Multiple users affected Reproduced across: Windows (New Outlook) Mac (similar behaviour reported) Not device-specific Not account-specific Troubleshooting already attempted App repair/reset Full reinstall Restarting WebView2 processes Clearing local app data No resolution (only temporary, same as killing task and restarting app). Observed pattern This appears to be isolated to the Calendar view UI layer, specifically: Modal/dialog rendering fails only when invoked from the Calendar canvas The same dialogs work when invoked from Mail context Suspected cause Likely a regression in the Calendar canvas/modal framework in New Outlook (Monarch) affecting dialog rendering. This is consistent with previously observed Calendar-specific rendering issues in New Outlook (UI-layer defects limited to Calendar view rather than Exchange Online service). Request Confirm whether this is a known or emerging issue Provide workaround or mitigation guidance Advise if this is linked to a recent feature rollout / flighting Share ETA for fix if available Workaround (confirmed) Use Mail view → New → Event Use Outlook Web (PWA) or Teams Calendar Additional notes (optional) Issue appears tied to Calendar view state rather than service/backend Switching views consistently resets behaviour (albeit not consistently/long term) Suggest investigating Calendar modal rendering lifecycle
