Outlook App Mac Slow To Sync

The main requirement for using Office 365 is an internet connection. You need an internet connection with high bandwidth and low latency. When using Office 365 online applications in a web browser and working with files in the cloud, a slow internet connection with high latency causes lags and delays. These Office 365 issues are inconvenient when you want to open a document or write changes to it, and can considerably slow down operations.

Automatic links are used to link objects (tables, diagrams, images, etc.) in other source documents with the current document. Content changes in a source document are reflected in your current document where the active link is inserted. Automatic links can be a reason why Microsoft Word is slow.

Add-ins are small programs that can expand Word functionality. Enabled add-in components are loaded during Word startup, increasing the time to open Word and being a reason for Microsoft Word running slow.

Removing OneDrive from automatic startup after the Windows boot can help you avoid Microsoft OneDrive slowing down a computer right after the OS starts until you research and fix the issue. This approach allows you to get normal performance on a computer with the ability to run OneDrive manually. After resolving OneDrive performance issues, you can add OneDrive to Windows startup.

OneDrive is the cloud storage to copy and synchronize files. However, the OneDrive Sync client is not a backup solution. If you use OneDrive to backup files, and Microsoft OneDrive is slowing down your computer, consider using a dedicated data protection solution that is optimized for transferring large amounts of data and includes advanced features for data protection.

The general recommendation is that you perform OneDrive backup to avoid data loss. You can lose OneDrive data if someone accidentally deletes the data or if a computer is infected with ransomware and corrupted data is synchronized between a local disk and OneDrive cloud storage.

Emails (slow & archive folders usually empty!) and contacts (useless ... tried everything inc bulk copy across to hotmail acc) Windows Outlook do not sync correctly with my icloud account ... have installed icloud app but only seems to help with photos otherwise probably better offer syncing without ... has anyone discovered a full proof way to use a icloud account successfully on a Microsoft laptop / Win 10 / Outlook ?

I'm pretty familiar with the way Outlook and Gmail work and have had problems with it in the past as many people do (as evidenced by all the problem posts found on Google). I've tried unsubscribing to all the folders but the Inbox. I've set the sync interval to 1 minute or 5 minutes or 30 minutes.

His old laptop did something similar with outgoing email taking a while to initiate sending or for new email to get fetched and they thought a new computer would fix it. The weird thing is that another computer being used in the office has another 2 gmail accounts plus this problematic account and it seems to be able to send and fetch WHILE the sync is in progress. While it's a little slow, it's much more responsive than the main user of the problematic email account. This other computer has Outlook 2016 and not the newer 2019 v1906 that's on the new computer, but the old laptop of problematic user also had Outlook 2016 and had problems.

I've gone through selective folder synching and only synching/subscribing to the Inbox. I've set Gmail to only allow synching of 1000 items in each folder. I've turned off Starred, Snoozed and Important folders for IMAP. I've set it not to update unread count and several other possible tweaks. Internet speed it good - cable modem at about 100Mbps down and 17Mbps up.

I know Outlook and IMAP Gmail isn't the best matched pair. That's why I tell clients to either use the gmail web interface or switch to something else. These aren't options at this point so I'm hoping there is a magic bullet that will make things run more smoothly. In general, with Outlook and Microsoft Exchange via Office 365, once a sync is done, syncs are very low overhead. I don't know why Gmail has so much of a time overhead to sync.

One thought I just had is that maybe if more than one Outlook is synching with the account, that can cause it to be slow. I'm not sure if the second computer was running Outlook when I tested, but perhaps the first Outlook that connects has better speed and the second and subsequent Outlooks connects to the same account get slow.

After playing around with all the settings in Outlook, there is a setting/checkbox in Define Send/Receive Groups --> Edit --> Receive mail items. There are two radio buttons. One is for Download complete items including attachments for subscribed folders and the other is for Use the custom behavior defined below. I chose the second setting and then selected ONLY the Inbox. This way ALL of the subscribed folders don't get synched when the sync happens. Back on the main Outlook screen, if a folder is clicked, it shows Synching folder xyz at the bottom of the screen and then updates that folder in real time to see any recent additions or deletions in the folder.

The default setting when adding a new IMAP email account is for the Download complete items including attachments for subscribed folders to be ON. For smaller mailboxes or ones without too many folders, maybe this is OK, but as the mailbox grows, it adds considerable time to the sync.

i've recently went through the same woes mapping a gmail, with a ton of subscribed folders filled with mail, to outlook and it took several hours for everything to sync and no mail would send or receive during that time (I actually did it twice for the same user and it took the same amount of time both times i.e. ridiculously long).

i always use this time to complain about using mail clients for webmail to my users. it just doesn't make sense. go to the source for the information instead of waiting for gmail to receive it and everything sync blah blah

Another thought would be to have the client create a free Microsoft email ( then connect only that account to the Outlook client. Now forward GMail to the new Microsoft email address and everything shows up in one account viewable in Outlook client.

@justgoogleit Yes, the settings I described are "how it is intended to work" though having to wait 60 seconds and even 2 to 4 or more minutes for a sync to happen is just too long. So having the default set to sync ALL folders when only the Inbox needs to sync seems to be a poor default. And the strange thing is that with devices like smartphones, they can connect to Gmail accounts and show all the data in all the folders (though it may not all be synced to the phone since it would fill up the storage) without lengthy delays. So it appears that the default for smartphones is to just sync the Inbox and to sync on the fly, other folders when they are selected. Your comment about it taking several hours when first doing a sync I agree with. I also know that and I expect that. But once the initial sync is done, then the syncs should be quick, but they weren't due to the continual synching of all the folders. I can live with the first sync being "slow" as I know it has to sync 11GB or 3GB or whatever is in the mailbox. I fully expect that. And I tell my clients that if they need to send mail and fetch new mail, to close Outlook, wait a few seconds for it to close in the background and then launch it again. Then Outlook will first send mail in the Outbox, check for new mail and then get back to the sync process. Once everything has synched, then this is not necessary. As far as using webmail, I would have to disagree. There are MANY reasons for using a local email program: having mailto: links work without having to do special setup, being able to have all the mail on the computer and scroll through it really fast without having to wait for page loads from a webpage, being able to use adding like label printing programs if that's needed, bing able to mail merge contacts, having Mail, Contacts, Calendars and Notes in one nice uniform program, etc. While I agree that webmail is going to the source and I always check the webmail interface when making sure credentials are correct, etc., I usually use a local program like Mac Mail or Outlook since they are more powerful than a web interface and also don't have the extra screen real estate take up by the browser buttons, etc. And if you advocate webmail, what do you do on a smartphone? Do you use webmail or do you use the built-in mail program go Google Mail, etc? I could not stand to use webmail on a smartphone due to the size of the screen and the constant refresh of data and the need for a continuous data connection.
