Outlook for Mac issue with contacts when saved
very strange issue with outlook for mac, if I add to contacts, the FILES, Messages and Linkedin tabs disappear. I contact microsoft support and they said this is a outlook for mac limitation but will look into it with internal team. Can anyone confirm they have the same issue ?JamesX1Jan 30, 2026Copper Contributor11Views0likes0Comments- ironfighterJan 30, 2026Occasional Reader3Views0likes0Comments
Classic Outlook Keeps "Not Responding" and freezing
Hi there, I tried to scour for something similar, but I couldn't find anything and/or it didn't work - so here I am - hopefully someone can help. Okay the facts - I use Classic Outlook (CO moving forward) and I run 5 email address in it - 3 are a domain for my company that I run and 2 are POP emails brought in from AOL. I run Windows 11. This is happening to 3 or my 5 work stations, all three are the ones on Windows 11. This started slow a few weeks ago, thought it was just low memory so went through and cleaned up old emails. I am not seeing these issues when using the 2 pop emails - just my company domain ones. Can open CO, taking some extended time but it is getting there. As soon as I try to send an email, reply to an email, change a signature within a new email - it either takes 5-10 minutes to load if we do not click again and just let it sit and think. The second I try and click something or try and scroll while waiting - it goes into 'Not Responding'. Some times it will load after 1 minute and sometimes it just get stuck. I have updated my CO, I tried the advanced 'online repair' through my system, I have tried disabling all my add-ons, I tried deleting my email account from CO and re-loading/logging in, I have checked my graphics card (something on google said to check it for updates), I have ran command prompts to check for internal Windows errors and I have come up short on everything.BrittanyNJan 29, 2026Copper Contributor1KViews1like17CommentsMicrosoft suspended my Outlook.com acccount for spam..a question.
I just started at being officer for a non-profit. I sent out email to our members that number about 300 people with a Forms survey asking about future meeting ideas. When I sent the email, it came back as being unable to deliver to all email addresses in the email (most of which were in the BCC column). I tried sending the email again and ended up with getting my account suspended. I finally was able to get a code to my phone and got my account active again. My question is would it be safe to send out emails to all our members in the future. From what I read, Microsoft Outlook allows up to 500 people. Our organization has much less that that. If I used this account again, would I risk it being suspended or permanently disabled again? I only link I had was for a Microsoft Forms survey.B_Van_SpanjeJan 29, 2026Brass Contributor34Views0likes2CommentsOutlook Desktop ignores or inactivates From address in programmatically generated files
I’m programmatically generating emails using Python within a Flask application. These emails are intended to be sent from a shared mailbox via the desktop Outlook application. In the code, the From: field is explicitly set to the shared email address (e.g. email address removed for privacy reasons). The application generates and downloads an .eml file, which is then opened in Outlook for review and manual sending. However, when the .eml file is opened in Outlook, one of two undesired behaviors occurs: The From field automatically switches to my individual default user email, ignoring the shared email specified in the code The From field visually displays the shared email, but Outlook treats it as not actually selected / not connected, and the email cannot be sent. In this case, manually selecting a different From address and then re-selecting the shared email allows the message to send successfully. In other words, even when the shared email appears in the From field, Outlook does not seem to treat it as an active or authenticated selection unless it is manually toggled. Has anyone encountered this behavior and have suggestions on how to rectify? Thank you!bellelunaJan 29, 2026Occasional Reader6Views0likes0CommentsFlagged Emails in New Outlook: Set Reminders and Due Date
I understand that transitioning from Classic Outlook to New Outlook can be intimidating and frustrating, especially regarding the feature changes. I'm here to help you navigate through the differences and make the switch as smooth as possible. You can access your flagged emails via the MyDay icon located in the top menu. Here are the steps to set reminders, due dates, and more. 1) Select the My Day icon 2) Click on the To-Do Tab (Note: Usually, this tab defaults to 'Tasks' for the primary mail account.) 3) If you manage multiple accounts, choose the correct mail account. 4) Select Flagged Emails: All flagged items for the select account will appear here 5) Right-click on any flagged item, and you will see many settings, including Set Reminder and Set Due date. I understand that completing the requirement involves many steps. It can be challenging, but I expect more improvements in the future. I hope this helps. /Teresa #traccreations4e 01/18/202419KViews1like7CommentsNon-Office 365 accounts repeatedly request sign-in each time Outlook (new) is opened or restarted
My Setup : Operating System: Windows 11 (fully updated, including latest Dell laptop BIOS/firmware) Office Version: Microsoft 365 Apps (licensed under Office 365 Standard for one of the email accounts) Outlook Version Used: Primarily the New Outlook for Windows Email Accounts Involved: One Office 365 Exchange account: email address removed for privacy reasons (credentials persist without issues) Multiple Gmail/IMAP/SMTP accounts (e.g., email address removed for privacy reasons, email address removed for privacy reasons, email address removed for privacy reasons, email address removed for privacy reasons) (all require reauth every time Outlook is opened) Symptoms Non-Office 365 accounts repeatedly request sign-in each time Outlook is opened or restarted. No error messages—just continuous web auth prompts for Gmail, SMTP, and IMAP accounts. The single licensed Office 365 account retains its credentials without issues. Troubleshooting Steps Already Tried Uninstalled/Reinstalled Office 365 Completely removed Microsoft 365 (via Apps & Features or Control Panel). Reinstalled Office 365—accounts still persisted upon first launch of Outlook, leading to repeated sign-in prompts again. Cleared Windows Credential Manager Removed all stored credentials related to Outlook, MicrosoftOffice16_Data:OAUTH2, Gmail/IMAP references, etc. Verified credentials were gone before relaunching Outlook. Removed Registry Keys & Data Under HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity, deleted leftover Identities referencing old accounts. Under HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Settings, removed the Accounts key containing JSON references to old addresses. Removed/cleaned up values in the Data subkey referencing _AccountSignaturesMigrated, _UserOptionsMigrationState, etc. Deleted Local AppData & Roaming Outlook Folders %LOCALAPPDATA%\\Microsoft\\Outlook %APPDATA%\\Microsoft\\Outlook Checked/removed possible OST/PST data in %USERPROFILE%\\Documents\\Outlook Files Removed Email & Accounts in Windows Settings Under Windows 11 Settings → Accounts → Email & accounts, confirmed the problematic addresses were removed. Checked for Security Software Conflicts No third-party antivirus, firewall, or VPN is interfering. Tried “New Outlook” Command-Line Wipe Attempted outlook.exe --clearLocalState (or olk.exe --clearLocalState) to remove local cache. Re-launched Outlook, re-added accounts—still facing reauth loops. Ensured Windows & Dell Firmware/Bios Up to Date Double-checked the system is fully updated (Windows Updates, Dell updates). Result Issue Not Resolved: Gmail/IMAP accounts continue prompting for sign-in each time Outlook starts. Only the Office 365 Exchange account retains its credentials as expected. After exhaustive attempts, reverted to Classic Outlook because it does not prompt for repeated sign-ins. Please let me know if this is a known bug that Microsoft is actively addressing. Are there any other steps I can take beyond local registry/credential cleanup to permanently resolve the repeated OAuth prompts?AndreaRJan 29, 2026Copper Contributor1.2KViews0likes2CommentsNot receiving emails from a specific email address suddenly
All of a sudden on 1/23/26 I stopped receiving emails from one specific email address. I checked my spam folder, made sure there were not rules associated with this particular email address, made sure the address was not blocked, and even added the email address as a safe sender but as of today I am still not getting the emails. Another person who is put on these emails when they are sent to me as well is having no issues and is still receiving them no problem. Not sure why this is happening all of a sudden or if there are any other settings I can check? I read that outlook was down last week and people were having issues not receiving emails but I believe this has since been resolved.JLH1Jan 29, 2026Copper Contributor23Views0likes1CommentProblems with Quick Steps in Outlook New
Sure! Here is the translation: "I am having issues with Quick Steps in the new version of Outlook. I have recreated them, but they appear blocked or as if they cannot be executed. However, sometimes they become available in a somewhat random manner. Can someone help me?"SolvedDanitroJan 28, 2026Copper Contributor2.3KViews0likes8Comments"Format picture" has disappeared from Outlook Mac
I use the Outlook app on 3 different MacBooks. Two have recently auto-updated Outlook to version 16.102.2, and I've lost the ability to format a picture in the body of an email. I use lots of screenshots in emails, and always put a border around them to clearly differentiate them from the body text. Right-click the image and select Format Picture from the menu. I can still do it in the third MacBook which is running Outlook version 16.84.2. I don't know if the latest update is meant to be an improvement, but I'm not happy about it! I'll turn off automate updates for the third MacBook. Not sure if I can revert the other two to version 16.84.2 - does anybody know if this is possible. Also wonder if users of the Windows app have experienced the same loss of the Format Picture feature?LynnProspectJan 27, 2026Iron Contributor1KViews6likes12Comments
